INTRODUCTION AND FEATURES

AMETEK Brookfield is proud to continue its leadership role in developing new technology for the moisture analysis industry. The Computrac® Vapor Pro® XL Autosampler is a revolutionary high-performance programmable moisture analyzer that measures low moisture levels and has the following features:

• A lower detection limit of 10 ppm, depending on the sample size.
• Operates through a user-friendly, color LCD touchscreen. The LCD automatically dims when the instrument is not used for 30 minutes, to conserve energy.
• A patented system that measures low moisture samples without reagents and correlates to the Karl Fischer coulometric titration method (with an oven attachment) in precision and accuracy. Consumables are minimized, and fragile and expensive glassware is not required.
• Up to 250 Test Programs (including the factory Test Programs) are available. Each Test Program contains test parameters such as sample size, heater temperature, and test ending criteria. Parameters are adjusted to optimize speed and accuracy.
• Test temperatures are set in one-degree increments from 25 °C to 300 °C.
• Results are available in:
• Parts per million water (ppm H2O),
• Micrograms water (µg H2O), or
• Percentage water (% H2O).
• AMETEK Brookfield’s pioneering prediction algorithm can reduce test times for some materials.
• The last 1000 Test Results are saved along with 100 Test Graphs:
• Tests Results can be viewed, printed, and downloaded using Internet Explorer®/Edge browser (with the optional Web Server) or sent to a PC over a USB or serial port.
• The mean, standard deviation, and relative standard deviation can be calculated for test results.
• Moisture graphs can be viewed and printed.
• In addition to AMETEK Brookfield’s standard 25 mL reusable sample vial, the oven accommodates crimp-top sample vial sizes from 2R to 30R. If necessary, the oven insert can be removed for larger diameter vials, which should only be done when the instrument is cold.
• An oven fan rapidly cools the oven to reduce wait time between Test Programs with lower temperatures.
• Periodic system and temperature calibrations maintain accuracy. NIST-traceable 1.0 µl pipettes (capillary tubes) permit quick and easy system verification. System calibration is checked in less than fifteen minutes. Recalibration is a menu-driven procedure to assure accurate and reliable results day after day.
• Built-in self-diagnostic routines continuously monitor system conditions to detect and report any abnormalities in the hardware, software, moisture sensor, or flow system.
• Designed for either lab or production floor use. Eliminating the expensive and fragile Karl Fischer glassware makes the instrument suitable for production floor use.
• An Audit Log tracks test program changes, calibrations, test result deletions, system errors, and power-on events.
• Download a complete calibration report.
• View the LCD screen.
• Download and upload Test Programs.
• Download Test Results and Test Graph data.
• Download the Audit Log.
• A User Login function that can restrict access to calibration functions and instrument, and test configuration options to only authorized users. When User Login is active, a user is required to log in before testing, and the user name is recorded with each test result.
• On 21 CFR, Part 11 compliant instruments, the Delete Test Results and Delete Audit Log Events functions are disabled throughout the system.

PRINCIPLES OF OPERATION

The Computrac® Vapor Pro® XL Moisture Analyzer uses patented, state-of-the-art technology to provide quick, accurate, and precise results. The instrument uses a cylindrical sample oven, a dry carrier gas flow system, and a moisture sensor. The instrument heats the sample, typically in a reusable 25 mL septum vial, driving off volatiles. The carrier gas transports the volatiles from the sample vial to the sensor block containing a polymer capacitor Relative Humidity (RH) sensor. The RH sensor output, sensor block temperature, and carrier flow readings are combined by a microprocessor to generate an accurate moisture measurement. Test parameters are adjustable to optimize speed and accuracy.

Applications

• Plastics
• Pharmaceuticals
• Batteries
• Oils
• Quality control

For those familiar with moisture analysis instruments, the Vapor Pro® XL should be simple to operate. However, please read all of the sections in this manual before attempting the first analysis.

A few materials are incompatible or interfere with the sensor. These are ammonium hydroxide, ethanol, methanol, and acetone. Samples containing these and similar chemicals should never be used. Additionally, never use these substances as cleaning agents in or on the Vapor Pro® XL.
Contact Customer Service if you have any questions about the instructions.

INSTALLATION

Place the Computrac® Vapor Pro® XL on a solid, level surface that is large enough to accommodate the instrument and any accessories or materials that may be required for your work (balance, printer, sample vials, samples, etc.).

• Perform the steps in this INSTALLATION section.
• Allow the instrument to warm up for 20 minutes.
• Perform a system calibration before testing (See “11.3. CALIBRATION SYSTEM CALIBRATION” on page 37).
• Set up a test program (See “9. TEST PROGRAMS” on page 26).

7.1. Instrument Location
The instrument is designed to provide reliable results under normal ambient conditions in the laboratory and on the production floor. Compliance with the following guidelines will help ensure optimum accuracy and minimum test times:

• Locate the instrument on a firm and level surface that is free from vibration.
• Locate the instrument close to an isolated power outlet that will provide a dedicated electrical power.
• Locate the instrument away from a fan, heating/air-conditioning vent, or drafts from a window/door.
• Maintain an operational clearance of 20 cm (8 inches) around the instrument and 1 m (3 feet) above the instrument.
• Keep all cables less than 2 meters (6 feet) in length, if possible.
•  Avoid placing the instrument close to a heater or otherwise exposing it to heat or direct sunlight.
• Avoid exposing the instrument to extreme temperature fluctuations.
• Keep the instrument protected from dust, liquids, and caustic vapors as much as possible.
• Do not expose the instrument to saturated humidity environments. Moisture in the air can condense on a cold instrument’s surfaces whenever it is brought into a substantially warmer place. If you move the instrument to a warmer area, make sure to condition it at room temperature by disconnecting it from AC power for one (1) hour and until moisture condensation no longer occurs.

7.2. AC Power Connection
Power Requirements: 100-120 VAC, 50/60 Hz @ 8 Amps 220-240 VAC, 50/60 Hz @ 4 Amps
Fused on/off switch is part of electromagnetic interference (EMI) power entry module
The instrument can be used with a 100-120 VAC or a 220-240 VAC input power source. Check the setting on thefuse holder located at the rear of the instrument. Make sure it is set to the correct voltage for the local power linevoltage. Ensure that the power entry module (where the power cord connects to the instrument) is set to the correct voltage for the local power line voltage.

To change the voltage from 110-120V to 220-240V or from 220-240V to 110-120V:

• Ensure the power switchlocated next to the fuse holder, is in the off (O) position.
• Remove the power cord, if connected.
• Pry the fuse holder from the power entry module.
• Ensure only 8 amp fuses are installed for 100-120 VAC operation, or only 4 amp fuses are installed for 220-240 VAC operation. Note the installation positions of the fuses before switching fuses.
• Rotate the fuse holder 180º and reinstall it in the power entry module, ensuring that the Voltage Marker (shown above) indicates the proper voltage for the local power line voltage.

Connect power to the instrument:

• Ensure that the power switch located on the power entry module in the instrument’s back, is set to Off (O).
• Remove the power cord from the packing material and insert the rectangular end firmly into the power entry module.
• See “7.4. Accessory Connections” on page 15 and its subsections for accessory connections.

7.3. Dry Air Or Nitrogen Connection

Using 1/8″ ID clear tubing [P/N 345-0050], attach dry nitrogen or dry carrier gas source to the Flow Inlet Port fitting on the back of the instrument, indicated by an arrow pointing towards the fitting.

• Dry carrier gas source may be a cylinder, facility air or nitrogen supply, or a dry air generator.

• The pressure from a compressed gas cylinder is very high and is normally reduced by a two-stage regulator. The pressure from the compressed air or nitrogen system in most facilities will be moderate and usually requires only a single-stage regulator. The dry air generator, manufactured by AMETEK Brookfield [P/N Y990-0143], produces the pressure required by the instrument and therefore, no additional regulator is needed. The dry air generator is the ideal choice for portable operation.

• Examples of regulators capable of regulating pressure to below 30 psi are as follows:

• For cylinder applications: Multi-stage Gas Regulator for Compressed Air Cylinder, VWR #55850-474, or equivalent.

• For supplied gas sources: Matheson Gas Products Model 3473 Single Stage Line Regulator or equivalent.

• Connecting tubing must be P/N 345-0050 clear impermeable tubing, unless otherwise indicated, to prevent introducing moisture into the carrier gas system. Tubing size is 1/8” ID x 1/4” OD.

• A desiccant bed is recommended to remove any moisture that may be present in the carrier gas supply. A desiccant kit is available as P/N Y990-0116. As illustrated on the next page, the desiccant is placed just before the instrument’s inlet connection. The
  desiccant turns from blue to pink as it absorbs moisture. When the entire column of desiccant is pink, it will no longer absorb moisture, and the desiccant must be replaced or regenerated to restore the drying capacity.

• Instructions on the Drierite® website show how to regenerate the Drierite® for continued use. For further information, contact W.A. Hammond Drierite Co, Ltd at 937-376-2927 or at www.drierite.com.

The following diagrams are not to scale but illustrate the preferred connection arrangements.
Using a Compressed Gas Cylinder
The cylinder with a two-stage regulator is connected to the desiccator with clear tubing [P/N 345-0050]. The desiccator is connected to the instrument with the same type of tubing.
The pressure to the instrument is between 17 and 22 psi (118-152 kPa). Using Facility Air or Gas Supply
The facilities air or gas supply is usually connected to a wall or bench mounted regulator. The regulator is connected to the desiccator with clear tubing [P/N 3450050]. The desiccator is connected to the instrument with the same type of tubing.
The pressure to the instrument is between 17 and 22 psi (118152kPa).

Using a Dry Air Generator
The dry air generator is connected to the desiccator with yellow tubing [P/N 2500 3003]. The desiccator is connected to the instrument with clear tubing [P/N 345-0050]. Pressure from the Dry Air Generator is not adjustable but should be above 14.5 psi (100 kPa).

For all but the dry air generator, adjust the pressure to the instrument so that it is set between 17 and 22 psi (118-152 kPa) with 20 psi (138 kPa) being the preferred pressure.
Once the instrument is installed and the dry gas is connected, check the flow and adjust if necessary, according to “18.6. Flow Check and Adjustment” on page 65

7.4. Accessory Connections

7.4.6. Connecting a Bar Code Reader
An optional bar code reader [P/N GV-1412] is available from AMETEK Brookfield that allows rapid data entry. Alphanumeric data can be entered into the instrument using the instrument touchscreen, a USB keyboard, and/or the bar code reader. When the field for the item to be input is highlighted on the instrument, simply scan the barcode to populate the item.
For example, if the test samples are labeled with bar codes, the bar code reader is useful to scan the LOT NUMBER and ID at the start of a test. See “12.4. SETUP→MISC OPTIONS” on page 46 for more information on LOT NUMBER and ID input.

• Unpack the bar code reader.
• Plug the bar code reading into the USB host port (marked USB) on the back panel.
• When the bar code reader is connected, the keyboard icon appears at the top of the Main Screen.

Note: The bar code reader also acts like a USB keyboard, and only one keyboard device can be connected to the instrument at a time. To use the keyboard, the bar code reader must first be disconnected from the instrument or USB hub, and vice versa.

OPERATING INSTRUCTIONS

• During power-up, the screen momentarily displays the firmware revision and the serial number of the instrument.
• Touching the screen while this information is displayed initiates touchscreen calibration. The included resistive stylus [P/N 355-0167, no ink pens] is used to calibrate the touchscreen by following the on-screen instructions. This calibration is done at the factory and not typically required in the field.
• Next, the Main Screen shown below appears. (It may be necessary to press the OK button to clear any messages).
• The LCD automatically dims when the instrument is not used for 30 minutes, to conserve energy. Pressing the touchscreen returns the LCD to full brightness.

The Main Screen displays the length and result of the last test, Test Program used, current oven temperature, oven temperature setpoint, and current system status. These results indicate WARMUP, and show a countdown timer if the instrument is drying down or READY TO TEST when the drydown is complete. The NEXT TEST field indicates what Test Program is currently selected and will be used if the TEST button is pressed.

The functions of the bottom row touchscreen buttons are:

• [MENU] – Touch to access the Main Menu.
• [PROGRAM] – Touch to select an already defined test program to be used for testing. Use MAIN MENU→ TEST PROGRAMS to add or edit test programs.
• [TEST] – Touch to begin a test using the currently selected Test Program.
• [GRAPH] – Touch to view the Test Graph from the last test that was run.

Note: Throughout this manual, [BOLD] text with square brackets indicates buttons or commands on this bottom row of touchscreen buttons. Other touchscreen buttons not located in the bottom row are shown in BOLD without square brackets.

Other user interface items:

• Home Button – The silver button beneath the LCD returns to the Main Screen, unless a Test is running, in which case it returns to the Test Screen.
• < RETURN or <RETURN TO PRIOR MENU – Non-editing screens are exited by pressing the upper left portion of the screen.
• Editing or text input screens are exited using the Enter button ( ) or the Escape button ( ), as explained below.

TEST PROGRAMS

The TEST PROGRAMS menu is used to create, select, edit, and print Test Programs and save them to or load them from a USB drive. The Computrac® Vapor Pro® XL can store 250 Test Programs. Each Test Program is optimized for a specific sample material (see §15 DETERMINE OPTIMUM TEST PARAMETERS on page 56). If desired, AMETEK Brookfield can help determine test program parameters for your samples. Contact the salesperson for details.

There are two different sets of buttons available from the Test Programs listing:

• The I/O KEYS: [SAVE], [LOAD], [PRINT], and [EDIT] (as shown in the image below-left).
  • The I/O KEYS are used to save Test Programs to a USB drive, load Test Programs from a USB drive, print selected Test Programs, or edit Test Programs.
  • Refer to §9.6 Saving And Loading Test Programs for guidance on using a USB drive to save Test Programs from an instrument or load Test Programs into an instrument.
• The MOVE KEYS: [CUT], [COPY], [INSERT ↑], and [INSERT ↓] (as shown in the image below-right).
  • The MOVE KEYS are used to create new Test Programs and for maintenance of the Test Programs listing.
• If the desired buttons are not displayed, press MOVE KEYS or I/O KEYS as appropriate to display the corresponding buttons.

To create a new Test Program:

• Begin at the Main Screen and select [MENU] to access the Main Menu.
• Select TEST PROGRAMS.
• Ensure that the Move Keys are displayed. If they are not, press MOVE KEYS to display them.
• Use the arrow keys to scroll to the last Test Program in the list and touch to select it. A black highlight bar indicates the selection.
• Touch [INSERT ↓] to insert a new Test Program below the last Test Program.
• Press I/O KEYS to switch to the I/O keys.
• Ensure the new Test Program is still selected and press [EDIT] to edit the Test Program, as described in the next sections.

9.1. SAMPLE NAME
At the TEST PROGRAM menu, touch SAMPLE NAME to start editing the sample name. To begin editing, select the gray text box. In edit mode, the current text is overwritten if the first key pressed is alphanumeric. Otherwise, use the cursor or the delete keys to position for editing.

9.2. TEST START OPTIONS

• VIAL PURGE time is the length of high flow time required to rid the vial of headspace moisture after the vial is pulled into the oven. Typically, 35 seconds of purge time removes the headspace moisture. This time can be shortened if sample moisture is being lost during the purge. A significant moisture rate right after the purge time indicates that sample moisture is being lost.
• RESIDUAL VIAL MOISTURE is subtracted from the sample result. This is the headspace moisture that is not removed by the VIAL PURGE. A zero VIAL PURGE time can be used to capture all sample moisture, but an expected RESIDUAL VIAL MOISTURE amount must be used to get good test results. Running empty vials with zero VIAL PURGE time gives the approximate headspace moisture. When room humidity changes, the headspace moisture changes.
• SAMPLE PROMPT is a short user-defined message displayed when starting a test, such as “LOAD 5 GRAMS” or “USE 2.0G +/- 0.2G”.
• SAMPLE WEIGHT ENTRY – Test result units, except µg H2O, require SAMPLE WEIGHT ENTRY to be set up in the TEST START OPTIONS. See “9.5. RESULT DISPLAY OPTIONS” on page 32 for additional information on the result display options.

To configure SAMPLE WEIGHT ENTRY, select Manual or Balance:

• Manual:
  • At the start of each test, the instrument will query the user for the sample’s weight.
  • If fixed weight samples are used, enter the weight in the DEFAULT WEIGHT field.
  When the instrument queries for the weight, accept the default weight to proceed.

• Balance:
  • At the start of each test, the connected accessory balance is used to measure the sample weight, and the instrument queries the user for acceptance of the measured weight. This value can be manually overridden if desired.

• Note: See “10. TEST RESULTS” on page 35 for instructions on entering the weight of the empty vial and cap after the test, for pre-sealed sample vials where the initial sample weight includes the weight of the vial, cap, and sample.

• DEFAULT WEIGHT – If using MANUAL Sample Weight Entry and fixed weight samples, the default sample weight can be entered here, as noted above.

• CALC WEIGHT FROM VOLUME – For some materials, such as liquids, samples are more easily measured by volume than by weight. If the sample’s volume and density are known, the instrument can use these values to calculate the initial sample weight.

• Pressing CALC WEIGHT FROM VOLUME displays the screen shown below left, and the sample VOLUME and DENSITY can be input. When CALC is pressed, the instrument will calculate the DEFAULT WEIGHT for the sample and will update the SAMPLE PROMPT and DEFAULT WEIGHT values, as shown in the image below-right.

9.3. TEMPERATURES

• TEST TEMPERATURE is the temperature setpoint for the test.
• If enabled, COLD START begins testing at room temperature instead of at the specified TEST TEMPERATURE. During the test, the oven ramps up to the TEST TEMPERATURE instead. COLD START is rarely used.
• If enabled, the TEMPERATURE STEP puts the instrument into a special test mode. The instrument starts a test at the TEST TEMPERATURE and ends normally. A following test automatically begins with the temperature increased by the STEP INCREMENT amount and ends normally. New tests are started until the stepped temperature exceeds the MAX TEMPERATURE. Each stepped test is saved.
• TEMPERATURE STEP modes available are Off, Accumulate results, or Individual results. ‘Individual’ records the results of each test separately, while ‘Accumulate’ adds the moisture of the previous tests to the current result. ‘Accumulate’ mode is good for determining the temperature when a sample releases moisture and can help determine the proper test temperature.

9.4. TEST END OPTIONS
Tests end based on the ending criteria specified for END ON, as explained below.
Rate: Ends the test when the moisture evolution rate drops below the set µg/s value. Use RATE if you want to match an existing standard or method that utilizes RATE criteria (such as the KF titration method). This method is commonly used.
Predict: The instrument uses an exponential decay formula to calculate the final result before all moisture is driven from the sample. This function reduces test times without sacrificing result accuracy. Some sample materials are amenable to this feature, but  many are not. If desired, try ‘Predict’ and compare results with the current method. RELIABILITY determines how long the test should be run based on how close to the calculated value the current results must be., The process is based on the following equation.
Reliability = (Current Moisture Measured So Far) / (Calculated Moisture) * 100%
Typically, 90% is a good starting value.

Time: Ends the test when the set time has elapsed. Fixed time ending is seldom superior to other ending criteria, but is useful when:

• Conducting application characterization tests,
• Investigating long-term stability of the instrument or material.

Time → Rate: Ends the test when the moisture evolution rate drops below the set µg/s value after the set time has elapsed. This ending criterion is useful for:

• Samples that take a long time to heat up before evolving moisture (the rate curve stays low for a while before rising significantly).
• Samples that have a double peak evolution rate curve. Use the time set to extend the test past the first evolution rate peak.

These are only guidelines. Experiment with the sample to refine the size estimates to achieve the desired speed and accuracy. If using a rate-ending criterion, and the peak moisture rate is less than five (5) times the rate threshold, the sample sizes should not vary more than about 10%. A large sample size variation may lead to a larger result variation. For your particular application, contact Customer Service for assistance in developing specific parameters.

9.5. RESULT DISPLAY OPTIONS
Results can be displayed in selected units, as specified in the RESULT field:

• Parts per million water (ppm H2O),
• Micrograms water (µg H2O), or
• Percentage water (% H2O), or
• Custom percentage water (% H2O), explained on the next page.

Result display units, except µg H2O, require SAMPLE WEIGHT ENTRY to be set in the TEST START OPTIONS, as explained in §9.2 TEST START OPTIONS (repeated on the next page for convenience). PASS/FAIL – If PASS/FAIL is set to ON, a LOW LIMIT and a HIGH LIMIT can be specified for the Test Result. When the test completes, the Main Screen will be GREEN and show [PASS] to indicate Passing results or RED and show [FAIL] to indicate Failing results, as shown in the image. The corresponding results will also display with a GREEN or RED font in the Test Results listing, as shown on the right.

• SAMPLE WEIGHT ENTRY – Select Manual or Balance:

•  Manual:

  • At the start of each test, the instrument will query the user for the sample’s weight.
  • If fixed weight samples are used, enter the weight in the DEFAULT WEIGHT field. When the instrument queries for the weight, accept the default weight to proceed.

• Balance:

  • At the start of each test, the connected accessory balance is used to measure the sample weight, and the instrument queries the user for acceptance of the measured weight.
    This value can be manually overridden if desired. Note: See §10 TEST RESULTS for instructions on entering the weight of the empty vial and cap after the test, for pre- sealed sample vials where the initial sample weight includes the weight of the vial, cap, and sample

• DEFAULT WEIGHT – If using MANUAL Sample Weight Entry and fixed weight samples, the default sample weight can be entered here, as noted above.

• Custom percentage water (% H2O) – This feature is primarily used with very viscous samples that require dilution with an anhydrous liquid solvent to reduce the viscosity to facilitate sample handling. A MULTIPLIER is used to compensate for the change in sample weight caused by the additional weight of the solvent, as shown in the example below. Custom UNITS can be specified for the compensated Test Result.

Example:

• Sample size: 2 grams
• Solvent added: 1 gram
• Total sample size: 3 grams
• Since the sample size was increased by 50% from 2 grams to 3 grams, the MULTIPLIER is set to 1.5000.
• The Vapor Pro® XL will multiply the percentage of water measured by the specified multiplier and then display it in the custom UNITS specified, as shown in the image, along with the total micrograms of water measured.

9.6. Saving And Loading Test Programs
Test Programs can be saved to a USB drive from the Vapor Pro® XL for storage/archive or transferring and loading into a different Vapor Pro® XL from a USB drive. This function can help ensure that the Test Programs are the same on all of theVapor Pro® XL’s at your facility or across your organization.From the Test Programs listing, if the I/O KEYS (SAVE, LOAD, TEST, PRINT, and EDIT) are not displayed, press I/O KEYS to display them.
Press [SAVE] to save Test Programs to a USB drive or [LOAD] to load them from a USB drive, and then follow the on-screen instructions.

CALIBRATION MENU

The calibration functions available to the end user are on this menu.
They are:

• Flow Sensor Calibration
• System Calibration and Verification
• Temperature Calibration and Verification

Temperature Calibration, if performed, should be done before any System Calibration.
NOTE: The calibration steps described in this section may invalidate the instrument factory calibration if not performed as directed. Contact Customer Service if you have any questions about performing these calibrations. Any other instrument calibrations can only be performed at the factory or by certified AMETEK Brookfield Field Service Engineers.

11.1. CALIBRATION →FLOW SENSOR CONSTANTS
If a digital volumetric flow meter is connected to the exhaust port, then the internal flow sensor can be calibrated by recalculating the Flow Correction Factor (FLOW CF) by following these steps:

• Remove the plug from the exhaust port (above the N2 input) and install the included Hose Barb (P/N: 345-0113).
• Connect a digital volumetric flow meter to the exhaust port.
• Measure the flow.
• Use the equation below to calculate the new FLOW CF, and then enter it in the FLOW CF field:
• The instrument displayed flow value, and the flow meter value should be within 0.2 mL/ min after the FLOW CF is updated.
• The LAST CALIBRATION date shown here will be updated when the FLOW CF is updated.

NOTE: Do not modify the FLOW @ values.

11.2. CALIBRATION → RH SENSOR CONSTANTS Do not change any of the values on this screen. Constants in this menu should only be modified with factory consultation. Changing these values can adversely affect instrument performance. Typically, these values are for factory use only.
11.3. CALIBRATION → SYSTEM CALIBRATION
System calibration and verification ensure that the instrument is accurately measuring evolved moisture. Daily verification is recommended. If verification fails, the system can be recalibrated.
The system is calibrated and verified using the same procedure, as described below. The difference between calibration and verification is how the results are used:

• When a system calibration is performed, the instrument uses the selected tests to recalibrate the system.
• When verification is performed, the instrument analyzes the selected tests to confirm successful system calibration.

Procedure for Calibration or Verification:

• Select either PERFORM CALIBRATION or PERFORM VERIFICATION, as appropriate, and proceed as follows:

• Read the on-screen instructions.

• Select [TEST] to perform three or more tests (five tests are the recommended maximum).

• The instrument will switch to the “(Factory) SYSTEM CAL” test program and return to the Main Screen.

• See §11.3.1 Pipette Loading on page 43 to load pipettes before a test. When the system status is “READY” on the Main Screen, press TEST and follow the on-screen instructions to perform the test. Each test takes 3 to 5 minutes.

• After testing, return to the PERFORM CALIBRATION or PERFORM VERIFICATION menu, as appropriate, but instead of pressing TEST, press SELECT to display the completed tests.

• Touch the desired tests and then select [CALC] to proceed or [CANCEL] to exit.

• After calculating is complete:
  • If calibrating: If the SD ≤ 30µg, select SAVE.
  • If verifying: If the Mean is within 950µg to 1050µg and SD ≤ 30µg, select SAVE.
  • If the verification Mean is out of spec, use the water tests for calibration instead by exiting and selecting PERFORM CALIBRATION, and then selecting the tests.

• After SAVE, the calibration report is displayed. Use VIEW CALIBRATION REPORT to view the report later.

• If calibration was performed, repeat the above steps to perform a verification.

11.3.1. Pipette Loading
Consumables for calibration:

• Sample Vial – 990-0229

• Septa for Sample Vials – 990-0207

• 1.0 µL Microcaps Pipette, 100/container – 990-0150

• Carefully remove a 1.0 µL Microcap Pipette [P/N 990-0150] from the storage container. Use forceps or tweezers [P/N 690-0028] to handle the tube.

• A new pipette is recommended for each test. However, most pipettes can be successfully loaded twice, while a third use often fails to load the pipette fully.

• Use a new sample vial to hold purified or deionized (DI) water for testing. Keep the DI vial loosely capped during testing to prevent dust from getting into the water. After testing, tightly cap the vial for future testing.

• Just touch the end of the pipette into the water. The pipette must be in contact with the water long enough to fill, about 10 seconds. Swishing the pipette end in the water can reduce loading time. If the pipette is not full, the reading will be low.

• Pull the pipette straight out of the water. Excess moisture may be on the side of the pipette, which causes high readings. Wipe the bottom end of the pipette between a clean finger and thumb. (A folded Kimwipe® tissue can be used too, but wipe quickly.Tissues can easily wick water out of the pipette, so start by applying pressure to the tissue above the pipette and quickly pull the tissue towards the end and off the pipette. Minimize all tissue contact with the pipette end.)

• Angle a cool, dry sample vial and gently place the pipette just past the vial’s neck, as shown in the image. Let the pipette slide to the vial’s bottom.
  Dropping or shaking the pipette causes water loss and erratic results.

• Install a septum into a dry cap [P/N 990-0206], so the shiny side of the septum (the Teflon® liner) is facing into the sample vial, and then screw it on. (The other silicone side of the septum must be facing out of the vial or results will be affected).
  Initially, use a new septum; one septum is good for multiple tests.

• Gently place the sample vial onto the transport and close the vial ramp cover.

11.4. CALIBRATION → SYSTEM CALIBRATION VIEW → CALIBRATION REPORT
The SYSTEM CALIBRATION REPORT shows the last calibration and verification results. It also shows the system linearity calibration and linearity verification, which are performed at the factory.

11.5. CALIBRATION → TEMPERATURE CALIBRATION
The temperature calibration and verification process takes approximately 3 hours.
Temperature Calibration Interface (TCI) Kit:

• P/N: Y990-0142 (115 VAC)

• P/N: Y990-0165 (230 VAC)

• Turn off the Vapor Pro® XL.

• Install the Temperature Calibration Probe into the calibration port to the rear of and below the vial ramp, as shown in the image.

• The probe must be inserted all the way in until the handle touches the case.

• Using the included 9-pin serial cable, connect the black Temperature Calibration Interface (TCI) box to the TCI port (marked TCI / BALANCE) on the Vapor Pro’s back panel ® XL.
  The TCI and probe serial numbers and calibration date shown on the TCI box will be recorded below.

• Plug the AC adaptor into the appropriate AC outlet and connect it to the TCI box.

• Turn on the Vapor Pro XL®.

• Navigate MAIN MENU → CALIBRATION MENU → TEMP CALIBRATION MENU

• Select the CALIBRATION MODULE SETUP and enter the appropriate data for the MODULE serial number, PROBE serial number, and calibration date (CAL DATE), as listed on the labels on the TCI box.
  Then, press the upper left corner of the screen to return to the TEMP CALIBRATION MENU.

• From the TEMP CALIBRATION MENU, select VERIFICATION SETUP. The purpose of the verification function is to confirm whether the calibration was successful at a given set of temperatures. The verification process can automatically follow the calibration by selecting Yes at the AUTO VERIFY AFTER CAL prompt.
  The rest of these instructions assume that the verification is run automatically, i.e., AUTO VERIFY AFTER CAL is set to Yes.

• If desired, set ADDITIONAL VERIFY TOL to a wider range than the standard verification tolerance of within ± 1.0 °C. Otherwise, leave set to “0.0°C.”

• If desired, set POINTS TO VERIFY to 1 to 4 Custom Points for specific verification temperatures. Otherwise, leave set to “All Cal Points.”

• To set specific verification temperature(s), touch the gray text box for the desired CUSTOM POINT to edit it. The selected temperatures should best represent those used for your product(s).

• When the VERIFICATION SETUP options are set as desired, press the upper left screen corner to return to the TEMP CALIBRATION MENU.

• Select PERFORM CALIBRATION; the next screen prompts you to attach the temperature calibration device. If the device is hooked up, press START.

• When the verification is complete, the instrument displays the TEMP VERIFICATION RESULTS. The DETAIL page shows the Pass/Fail results at each checkpoint.

• If the unit failed at any given point, rerun the calibration to improve the results.

• If a printer is connected, select PRINT to print out the calibration report.

• Calibration is complete.

• Disconnect the calibration module.

The probe may be hot from the last calibration or verification.
So, grab the probe only by the handle.

SETUP MENU

The SETUP MENU is used to set up and configure the instrument options described in this section.![AMETEK Brookfield CT-4200XL Computrac Vapor Pro XL

• SETUP MENU](https://manuals.plus/wp-content/uploads/2024/01/AMETEK- Brookfield-CT-4200XL-Computrac-Vapor-Pro-XL-SETUP-MENU.jpg)

12.1. SETUP → PRINTER SETUP
PRINTER SETUP is used for configuring where data is sent whenever a PRINT button is pressed on the instrument.
Available data output options are output to a computer, a printer, a USB drive, or any combination thereof, as shown in the image below. Note: Test Graphs are only sent to the printer.
The following options are available:

• OUTPUT TO COMPUTER sends reports to the USB PC port.
• OUTPUT TO USB DRIVE sends reports to a USB drive. Make sure to insert the drive in the USB host port (marked USB) before printing a report. When a report is printed, a file name is constructed from the instrument’s serial number with a “.TXT”  extension (for example, “42000000.TXT”), and the report is saved to the drive. As reports are printed, they are appended to this file. Always wait 5 seconds after a report finishes before removing the drive to allow the instrument to close the file. Otherwise,  drive corruption can occur.
• OUTPUT TO PRINTER sends reports to a printer. If using the standard printer [P/N Y990-0212], TEST PRINT can send a test pattern to the printer to check the functionality. The TEST PRINT does not send the test pattern to a connected computer or USB drive.

12.2. SETUP → REPORT SETUP
This menu enables and customizes reports.

12.2.1 SETUP →REPORT SETUP→ REPORT CONTROL OPTIONS
The report control options enable automated reports to be printed.

The following options are available:

• FINAL TEST REPORT – when set to On, a test report prints after a test is complete.
• TEST PROGRESS – when set to On, progress reports are printed during a test, at the selected interval. Intervals of 1 second, 5 seconds, 10 seconds, 15 seconds, 30 seconds, and 1 minute are available. Shorter intervals can be useful for test program development, while longer intervals are more helpful during normal use.
• FINAL TEST GRAPH – when set to On, a moisture graph is automatically printed after the test completes. Graphs are sent only to the printer, not to the computer or USB drive.

12.2.2. SETUP → REPORT SETUP → REPORT ITEMS TO PRINT
Test Results include information that may not be needed in your application. Touch to select which items are required on the test report. The selected items are indicated by checkmarks, as shown in the image.

12.2.3. SETUP → REPORT SETUP → COMPANY NAME
The COMPANY NAME prints at the top of reports and may be used for the company name, test location, or other information.

12.2.4. SETUP →  DATE/TIME SETUP
Use this function to change the TIME and DATE at the initial setup or when updating the time for daylight savings time. Time is in a 24-hour format.
An internal battery maintains the correct time and date when the power is off. If an “RTC Battery Failure” occurs or the clock resets when the power is turned off and on, the internal backup battery may need to be replaced. If this happens, call Customer Service. A battery failure does not affect the instrument’s Test Programs, Test Results, or configuration options.

12.3. SETUP → ETHERNET SETUP
An optional Web Server can be purchased so that a Windows® PC can access the Vapor Pro® XL from your local area network (LAN) or intranet with Internet Explorer® (IE) v6 or higher, or Edge browser. Use the Ethernet Setup menu to configure the connection. Generally, the instrument cannot be viewed on the Internet because of company firewalls. But in some cases, it is possible and requires a registered IP address. If the Web Server option is not purchased, the instrument can still be accessed over the intranet to test the LAN connection. However, reports, data, and other functionality will not be available.

The following options are available from the ETHERNET SETUP screen:

• NAME & PASSWORD are used to restrict access to the instrument over the intranet. When prompted by the browser, enter the assigned NAME value for the user name and enter the assigned PASSWORD for the password to gain access to the instrument.
  NOTE: For best security, do not reuse a password.

• OBTAIN IP ADDRESS options are:
  • Ethernet Off – disables the Ethernet port.
  • Manual – requires the manual entry of IP ADDRESS, SUBNET MASK, and GATEWAY. Consult with your Information Systems (IS/IT) department for the correct settings.
  • Automatic (factory default) – sets everything automatically. A DHCP server on the network is required to use automatic mode. This mode is useful to check the operation of the Web Server. However, because the DHCP server may assign a new IP address each time the instrument is powered on, the end user would need to check the instrument Ethernet Setup screen to verify that the correct instrument IP address is used by the browser. Therefore, the Manual mode is generally preferred.

• MAC ADDRESS is factory set and is unique to every Internet device. It may be helpful to your IS/IT department.

If OBTAIN IP ADDRESS is set to Manual, do not use an IP address for the instrument that conflicts with another IP address on your network. Conflicting IP addresses may cause network crashes or instability. As an additional safeguard against conflicts, the instrument will not accept IP addresses ending in .255 or .1.
See §17 WEB SERVER for details on the Web Server. Call Customer Service for more information or to purchase and activate the Web Server.

12.4. SETUP → MISC OPTIONS
The following options are available:

• OVEN FAN ENABLED – when set to the default value of Yes, the oven fan turns on to speed cooling between tests. This feature helps decrease the cooling time required between tests at different temperatures.

• LOT NUMBER – if enabled, starting a test displays the ENTER LOT NUMBER AND ID screen. These entries may be used to insert the lot designation and unique product identifier into reports. This feature is turned Off by default.

• If the LOT NUMBER and PRODUCT ID are barcoded on the samples, the values can be scanned using the Bar Code Reader [P/N: GV-1412].
  Access the desired field, so the keyboard is displayed, and then scan the corresponding bar code to populate the field.

• STANDBY TIMEOUT reduces the oven temperature to the STANDBY TEMP after the specified timeout. When testing at high temperatures of 200 °C or higher, we recommend using this feature to reduce system wear and conserve power.

12.5. SETUP NITROGEN CONTROL
If using nitrogen gas cylinders, use this feature to conserve nitrogen when the instrument is idle. When nitrogen flow is off, selecting [TEST] on the Main Screen restarts the flow. The instrument waits for the flow to stabilize, and the test will begin when the system is READY. The following options are available:

• USAGE TIMEOUT enables a timeout, measured in minutes when the instrument is idle. Once the timeout reaches zero, nitrogen is shut off.
• ON TIME, OFF TIME, OPERATION DAYS – When ON and OFF times are different, the system shuts down nitrogen when outside of the specified times on the specified days. To test during the off times, set the usage timeout to enable nitrogen with a timeout even during the off times.

12.5. SETUP LOGIN SETUP
This menu allows the setup of user logins. If User Login is active, access to calibration and configuration options can be restricted to authorized users. Users must log in before testing, and the user name is recorded with each test result. Up to 20 users can be added.
LOGIN SETUP options are:

• ACTIVATE LOGIN: If enabled, users are required to log in before testing. Users log in and log out using the [LOGIN] and [USER] keys on the Main Screen (shown ).
• ADMIN KEY is the key required to access this LOGIN SETUP menu if restricted access to this menu is desired.

 DETERMINE OPTIMUM TEST PARAMETERS

For best accuracy and speed, the sample should evolve between 200 µg and 5,000 µg of water during the test.
Larger sample sizes do not significantly improve accuracy and extend the test time. Smaller quantities result in faster tests but may degrade accuracy depending on the properties of the sample.
The sample size can be entered in the test program’s SAMPLE PROMPT field (See “9.2. TEST START OPTIONS” on page 28). This will prompt the user to load the vial with a specific amount of sample at the start of the test. After determining the optimum test parameters, it is recommended to repeat the test to confirm the results.
For your particular application, contact Customer Service for assistance in developing specific parameters.
15.1. Starting With Karl Fischer Parameters
To match Karl Fischer (KF) analysis results, obtain the sample size and ‘sensitivity’ setting from the KF procedure.
Use approximately 1.5 to 2 times as much sample in the Computrac® Vapor Pro® XL, and set the rate ending criteria to the ‘sensitivity’ value used in the KF equipment.
Example:

| Karl Fischer| Vapor Pro® XL
---|---|---
Sensitivity Setting| 0.1 µg/sec| 0.1 µg/sec
Sample Size| 0.5 g| 0.75 – 1 g

Start at the KF test temperature and adjust as needed.
15.2. Parameter Development From Scratch
Use the following calculation to estimate the minimum sample size for a sample expected to have 200 µg water.
Minimum Sample Size (in grams) = 0.02 / (Expected Moisture in %)
Example:
If Expected Moisture is 0.05%
Then Minimum Sample = 0.02 / 0.05 = 0.4 grams
The following table gives general guidance for the selection of sample size for the expected moisture level. The sample vial also limits the maximum sample size. Do not fill the vial over a third full. This will typically be about five (5) grams for the sample vial used with the Vapor Pro® XL.
RECOMMENDED SAMPLE SIZE TABLE

These are only guidelines. Experiment with your sample to refine the size estimates to achieve the desired speed and accuracy. When using a rate ending criterion, if the peak moisture rate is less than five times the rate threshold, the sample sizes should not vary more than about 10%. A larger variation of sample size leads to a larger variety of results.
Use the highest possible temperature without causing other ‘undesirable’ conditions (such as melting or excessive release of other volatiles). Lower temperatures result in longer test times and possibly low results. In most cases, the sample must not melt. A melted sample may form an impermeable skin and trap moisture, producing an inaccurate result.
The following guidelines will help:

• If you have a reference method, set the test temperature to the same temperature as used in your reference method.
• If the melting temperature is known, set the temperature 10°C or 20°C lower.

For rate ending criteria, start with 0.3 µg/s for samples with 100µg moisture. 0.5 µg/s works well for larger sample moistures (500 to 10,000 µg). Adjust the rate ending criteria to target the desired test result value.

PERFORMING MOISTURE TESTS

Select the appropriate test program by selecting [PROGRAMS] from the Main Screen. If changing temperatures, wait for the temperature to stabilize, as indicated by the main screen’s thermometer. See “9. TEST PROGRAMS” on page 26 for creating and editing test programs.
Begin a test:

• Use a cool, clean empty sample vial with septum and cap.
• Wait for system status to read “READY” on the Main Screen.
• For ppm and % result output: Tare the empty vial on balance.
• If unable to tare the empty vial before testing, the vial weight can be entered through the TEST RESULTS screen after testing (See “10. TEST RESULTS” on page 35). This scenario occurs with prepackaged samples.
• Fill the sample vial:
• To prevent needle damage and manifold contamination, do not fill the vial more than one- third the volume.
• Press [TEST] and follow the on-screen instructions to perform the test.
• When prompted, weigh the loaded sample vial and enter the weight.
• Install a clean septum into a dry cap, so the shiny side (the Teflon® liner) faces into the sample vial, and then screw on the cap. (The other silicone side of the septum must face out of the vial or results will be affected). Septa are typically suitable for multiple tests. For liquid samples, wipe the septa clean before reuse.
• When prompted, insert the sample vial and close the vial ramp cover to begin the test.
•  An audible ‘beep’ sounds when the instrument completes the test.

NOTE: The accessory balance, P/N Y990-0082 (115V) or Y990-0083 (230V), communicates directly with the Vapor Pro® XL, eliminating possible transcription errors when entering the sample weight.

• CALIBRATION REPORT 5](https://manuals.plus/wp-content/uploads/2024/01 /AMETEK-Brookfield-CT-4200XL-Computrac-Vapor-Pro-XL-CALIBRATION-REPORT-5.jpg)

REPAIR, MAINTENANCE, AND OPTIONAL ACCESSORIES

Routine maintenance consists of checking the flow, checking the optional Hydrophobic Filter (see “18.5. Filter Inspection, Replacement & flow path cleaning” on page 64) for clogging or contamination, checking the needles for clogs, and cleaning the flow path between the needle and the filter. Ensure the instrument is cool.
18.1. LCD and Instrument Cleaning

• The outer housing of the instrument should be cleaned with a mild household detergent such as Formula 409 and a soft, lint-free cloth. Paper towels should never be used, as they will scratch the instrument’s finish.
• Clean the touchscreen LCD, only with a lens or eyeglass cleaner and a lens towel or Kimwipe. Paper towels should never be used, as they will scratch the LCD.
• If more aggressive cleaning is required, call Customer Service for recommendations.

18.2. Inserts for Crimp Top Sample Vials
If your samples use crimp-top vials, insert kits are available so the Vapor Pro® XL can accommodate them.
The two kits and their compatible vials sizes are:

• Y990-0271 Kit, Small Crimp Vials fits: 13mm cap size (2R and 4R vials)
• Y990-0272 Kit, Large Crimp Vials fits: 20mm cap size (6R through 30R vials)

Make sure the oven is cold before proceeding.
Place the insert into the standard vial holder, as shown in the image. When properly installed, the setscrew in the insert will fit into the matching indentation in the standard vial holder, preventing rotation of the insert. Replace the insert to switch to a vial with a different sized cap. If needed, a small hole to the right of the setscrew is used to remove the insert with a small pointed object, such as a pen tip. Testing makes the transport and insert hot, so wait for cool down. Protect your hands from heat, or use a tool to replace the insert.If using vials with an outer diameter of 28mm or more, it is necessary to remove the oven insert. Follow these steps to remove the oven insert:

• If the oven is hot, select the “(Factory) IDLE” test program for rapid cool down.
• Turn the instrument off.
• Unscrew and remove the indicated screw, then use tweezers to grab and pull the insert out of the oven.

Save the oven insert and screw for reinstallation if needed for other size vials. For reference, the oven insert is P/N 300-0962, and the screw is P/N 850-0259.
18.3. Cover Access

• Refer to this procedure to gain access to the internal parts as directed in other sections of this manual.
• If the instrument oven is hot, switch to the “(Factory) IDLE” test program to quickly cool the oven. Wait for the oven to cool down to prevent burns.
• Turn the power off and remove the power cord to prevent electrical shocks.
• Loosen (but do not remove) the Phillips®-head screw on the front of the case, and lift the cover.
• Leave the power cord disconnected while the case is open unless otherwise directed.
• The manifold is heated to 68°C during operation. So, avoid contact when working inside the instrument or wait for the manifold to cool down.
• Perform the desired maintenance.
• After maintenance, close and secure the top cover by pushing the case screw in, closing the top cover, and tightening the screw.
• Reconnect the power cord and turn on.

CAUTION
Line voltage and a heated oven are present under the instrument’s cover.
Turn off the power and remove the power cord to prevent electrical shock. Wait for the oven to cool down to prevent burns.
Secure the cover in place before reconnecting the power cord.
18.4. Hydrophobic Filter and Tubing Installation
For applications such as nylon or other materials with unreacted or unpolymerized components (such as caprolactam), a hydrophobic particulate filter is recommended to minimize potential contamination of the RH sensor manifold with condensed material. The complete filter kit, including the required fittings, is available as P/N: Y990-0266. Once the filter kit is installed, only the filter and tubing require regular maintenance, as described in the next section. To install the Filter Kit (P/N: Y990-0266):

• Follow the instructions in §18.3 Cover Access to gain access to the instrument.
• Use a slotted screwdriver to remove the indicated right fitting and the short piece of tubing attached to it.
• Use a slotted screwdriver to loosen, but do not remove, the indicated left fitting.
• Use a slotted screwdriver to install and secure the Filter Kit in the open hole.
• Rotate the left fitting to point away from you as shown in the image, then tighten it in place.
• Install the tubing between the barbed fitting (on the left) and filter.
•  Ensure that all fittings (including the Luer lock on the filter) are secure.

18.5. Filter Inspection, Replacement & Flow Path Cleaning
If the Hydrophobic Filter Kit is installed, refer to this section for inspection, replacement, and flow path cleaning instructions. For cleaner samples, such as most plastic resin pellets, this is seldom necessary. For very dusty, high moisture or high volatile content samples, this may be necessary more often. The Kit with just the filter and tubing is P/N: Y990-0267.

• Follow the instructions in §18.3 Cover Access to gain access to the instrument.
•  Examine the filter for any visible deposits or discoloration indicative of contamination.
• The tubing is opaque, so tubing contamination is not obvious. If contamination is suspected, replace the tubing. Tubing cannot be reused once removed. Slice open the old tubing to determine if the system is contaminated.
•  If a deposit or discoloration is observed in the filter or tubing, they should be replaced, and the entire sample flow path cleaned with isopropyl alcohol (IPA), as described below.

IMPORTANT
Never use methanol to clean any part of the instrument.
Methanol interferes with the calibration of the RH sensor, and is very difficult to remove from the flow system.
To replace the filter and tubing and purge the flow path:

• Obtain a new Hydrophobic Filter Kit from AMETEK Brookfield (P/N Y990-0267).
• Rotate the Luer locking ring to unlock the filter, and remove it.
• Detach the tubing from the barbed fitting (on the left).
• Discard the old filter and tubing.
•  Install the new filter onto the Luer fitting and rotate the locking ring to secure it.
• Install the tubing between the barbed fitting (on the left) and filter, as shown in the image bove.
• Refer to §18.3 Cover Access to close the instrument, restore power, and turn it on.
• If contamination was seen or is suspected, purge the sample flow path with isopropyl alcohol (IPA) by following these steps:
• If not already done, remove the plug from the instrument’s exhaust port (above the N2 input) and install the included Hose Barb (P/N: 345-0113).

• Press IN to move the transport and vial into the instrument and start the cleaning.
• When the IPA has stopped sputtering out of the output port, press OUT to move the
• Attach a short tube to the exhaust port and route the other tube end to a waste jar or beaker to catch the IPA expelled from the flow system.
• Reconnect the power cord and turn on.
• Select the Factory (IDLE) Test Program to keep the oven from heating.
• Fill a sample vial with IPA, place it in the transport, and close the vial ramp cover.
• Navigate to MAIN MENU SERVICE MENU SENSOR READINGS.
• When done flushing, remove the exhaust port tube and waste jar.
  Note: Factory replacement of the Hydrophobic Filter is available and recommended.

18.6. Flow Check and Adjustment
The instrument has a normal flow for idle and testing, and a higher flow for vial purge at the test start. The normal flow should be checked upon installation of the instrument and adjusted if needed. Weekly checks after installation are recommended.
Flow Check procedure:

• Verify that the pressure of the carrier-gas supplied to the instrument is between 17-22 psi, and the instrument has been powered on for 20 minutes with the gas connected.

• Begin at the Main Screen.

• Navigate [MENU] SEVICE MENUR SENSOR READINGS.

• Ensure that N2 FLOW is On and HIGH FLOW is Off.
  Touch to toggle if needed.

• Verify that the FLOW displayed is within 95.0 ± 5.0 mL/min. If so, no adjustment is needed. If not, continue to adjust the flow.

CAUTION
Line voltage and a heated oven are present inside the instrument.
Only technicians or users comfortable with this process should adjust the flow, as it is adjusted with the instrument powered ON.
Line voltage runs to circuits and components along the left side of the instrument.
Avoid touching any circuits on the left side of the instrument. The flow adjustment is performed in the front right corner, which is away from the hazardous voltages.
