Calibration
All balances are calibrated at the factory prior to shipment. However, you should calibrate your balance before using it for the first time, and you should periodically check calibration to ensure accuracy. We recommend that you check the calibration once a week, or when- ever the balance has been moved to a different location, or excessive temperature variations have occurred. Calibration weights are available from your sales representative. See Calibration Weight Chart located from the inside front cover.

Procedure (Example is for a 410g capacity balance.)

1. Press the ZERO key. The display shows: 0.000
2. Place the calibration weight on the pan. (Example: for a 410g capacity balance place a 400g weight on the pan.) The display may show: 400.001.
3. Press the CAL key. The display shows: CAL 400. Then, CAL GOOD. (It may display No Cal momentarily.)
4. When calibration is complete, the balance shows: 400.000g, the weight used.
5. Remove the weight. The display shows: 0.000g.
6. Unsuccessful calibration routine. The display shows: No CAL. This may occur, for example, if an incorrect calibration weight has been used. If necessary, repeat the steps 1 – 5 with a correct calibration weight.

BALANCE OPERATION

Zero (Tare)
The ZERO key serves three functions:

• Pressed briefly, the ZERO key zeros (tares) the balance.
• When the ZERO and PRINT keys are pressed simultaneously and held for 3-4 seconds, the weighing units will change.
• For Dual Range units only, pressing the ZERO key twice will switch to the low range.

To Zero (tare) the weight of a container:

1. Place the empty container on the weighing pan and allow the balance to stabilize. (The balance is stable when the motion indicator”; ” (a semicolon) at the right of the display disappears.)
2. Press the ZERO key. The display now shows 0.0. (Example: 0.1 readability.)
3. Now place the sample in the container. The display shows only the weight of the sample.

NOTE: Always wait for the motion indicator to disappear before taking a reading.

Weight Units
Your balance lets you weigh in different units, as well as count parts and perform percent weight functions. To change weighing units, press and hold the ZERO key and PRINT key simultaneously for 3-4 seconds, until the letter on the far right of the display changes to the appropriate unit of measure.

NOTE: Balance defaults to GRAMS upon being powered up.

The following letter abbreviations correspond to these weight units:

• Grams …. 9
• Avoirdupois Ounce …. O
• Grains …. G
• Pound …. L
• Parts/Percent…. P

The balance now weighs in the selected unit until changed or powered down. Other weight units are available through the 1/0 port. See page 12.

Dual-Range Models.

• Model 410D is a dual-range model that can weigh the first 61 grams to a readability of 0.001 grams. When 61 grams is exceeded, the balance switches readability to 0.01 grams for the remainder of the capacity.
• Model 3100D is also a dual-range unit. It can weigh the first 450 grams to 0.01 grams. When 450 grams is exceeded, the balance automatically switches readability to 0.1 grams for the remaining capacity.

Counting Parts
Your balance may be used to determine the number of identical parts in a sample. As described below, this is done by first calibrating the balance to a known number of parts (the control number).

NOTE: One part should have a weight greater than the readability. Example: A balance with 0.1 readability can not be used to count parts that weigh less than 0.1g.

Procedure

1. Press the ZERO key.
2. Place a container on the pan and allow the balance to stabilize. (If no container is used, proceed to Step 4.
3. Again, press the ZERO key.
4. Now hold down the ZERO and PRINT keys simultaneously while the menu scrolls though the options. Release the key when the display shows the desired control number, ie: PARTS 1, PARTS 10, PARTS 25, PARTS 50, PARTS 100, PARTS 200 & PERCENT. Small parts may require using a larger control number. (Other values may be entered through the 1/0 port. See page 12.)
5. Place the exact number of items on the balance which correspond to the control number. Wait for the stability indicator to disappear.
6. Press the CAL key. The display shows PARTS-CAL. The balance is now calibrated to count these items.
7. Place additional items to be counted on the balance. The balance automatically displays the number of items (un to the canacity of the balance).

Calculate Percent
Your balance may be used to compare the weight of a sample against a control weight. The sample weight will be displayed as a percentage of the control weight. Procedure

1. Press the ZERO key
2. Now hold down the ZERO key while the menu scrolls through weighing units and PARTS. Release the key when the display shows: PERCENT.
3. Place the control sample on the pan and wait for the stability indicator to disappear.
4. Press the CAL key. The display shows: PARTS-CAL and then 100.00. (The balance automatically selects the appropriate number of digits to the right of the decimal.)
5. Remove the control sample from the pan.
6. Place a sample on the pan. Example: Display shows: 97.00P, meaning that the current sample is 97% of the control weight. The display would show: -3.00P, if control weight had been zeroed prior to the sample weighing.

NOTE: The control weight must be of sufficient mass to allow proper operation.

Setup
The SETUP commands allow you to customize the performance of your unit.

To access the SETUP menu:

1. Simultaneously press the CAL and ZERO keys. Display shows: SETUP.

2. While SETUP is still displayed, press the ZERO key and hold to advance through the following menu:
   NOTE : The bolded settings indicate the default values that are automatically set when the balance initially is powered up.

   • FILTER ON 300 BAUD
   • FILTER OFF 2400 BAUD
   • AUTO-Z ON PRINT 1
   • AUTO-Z OFF PRINT ALL

3. To select: When the display shows the desired setting, press the CAL key. You may continue through the menu by pressing the ZERO key; otherwise, the balance returns to the weighing mode. To change any of the settings, repeat steps 1 through 3.

The SETUP parameters are lost when power is removed. To save the parameters, select the SAVE option (after entering parameters) and then press the CAL key.

• FILTER ON
  Displayed as FILTER ON. Sets the balance to average measured weight readings over a longer time period before displaying them. Use this setting when the balance is exposed to vibration or to air drafts.

• FILTER OFF
  Displayed as FILTER OFF. Use when balance is free of vibration or air drafts.

• AUTO-ZERO ON
  Displayed as AUTO-Z ON. Commands the balance to maintain the zero indication within specified limits. Use this setting when the balance is affected by disturbances that may cause small amounts of drift on the display. Also known as zero-tracking.

• AUTO-ZERO OFF
  Displayed as AUTO-Z OFF. Balance does not automatically re-zero itself.

• 300 BAUD
  Sets balance to transmit and receive data at a rate of 300 bits per second.

• 2400 BAUD
  PRINT 1 Sets balance to transmit and receive data at a rate of 2400 bits per second. Sets balance to send a single data string when the PRINT key is pressed.

• PRINT ALL
  Sets balance to send data continuously. SAVE Permanently saves the selected parameters, even when the power is lost.

NOTE: If a key is not pressed within four (4) seconds, the balance returns to the weighing mode.

INTERFACE APPLICATIONS

NOTE: Improper connections to the Input/Output (I/O) may result in damage to the balance.

Technical Specifications

Connector: RJ-11, 6 position, 4 conductor, modular telephone jack.

SIGNAL DEFINITION
This balance uses an RS-232C level compatible interface, with 8 data bits and null parity.

• Data Output : Voltage output is compatible with RS-232C levels, 300 Ohm source resistance and 8 volt swing minimum.
• Data Input: Voltage input compatible with RS-232C levels, 3000 Ohm input impedance, £5 volt minimum swing, +20 maximum voltage.

1/0 SPECIFICATIONS
It is important for the user to determine interface requirements of equipment connected to the balance. The maximum recommended cable length is 10 feet. The information is transmitted at either a baud rate of 300 or 2400 in standard ASCII format. (See SETUP).

OUTPUT SPECIFICATIONS
Data from the balance is transmitted in a similar format to that displayed on the front panel of the balance. For example, a typical string is: 1+00012.3 Each weight reading is followed by a carriage return and a line feed. If the reading is negative, a ” – ” will precede the numerical value instead of the ” +” symbol. If the reading is unstable, a ” U ” will precede the value instead of the ” 1 ” symbol.

1/0 COMMANDS

• It is possible to control the balance from a terminal or computer with RS-232C interface and baud rate of either 300 or 2400. The following UPPER CASE commands can be used. Some commands must be followed by a carriage return, as noted by . The symbol # designates a number following the command letter. Immediately zeroes (tares) balance to zero.
• ?# Prints the data a specific number (#) of times. This number (#) can be 0 to 9. If a number 1 through 9 is selected and the balance is unstable, the balance will wait for a stable condition before sending the data. For example, if ” ?4″ is transmitted to the balance, four consecutive, stable weight readings are output from the balance in the format specified in 1/0 Com mands above. If the number (#) is zero, the balance will continuously output weight readings, whether the balance is stable or not. If a reading is unstable, a ” U ” symbol will precede the weight value.
• F# Function select. The balance goes into the function number # chosen from the table below. It is not necessary to remove the weight or tare when changing functions.

SYMBOLS

DISPLAYED

• CAL <C> The calibrate command allows the user to re-calibrate the balance using the allowed calibration weights. To use, place the calibration weight on the pan and send the calibrate command. See Calibration section.
• M “enter message <cr> For entering any message, up to 10 characters, type for readout on the message” display.
• P### Parts Re-calibration. Allows the user to display a number to represent the weight on the pan. This can be used for counting, check weighing or conversion to other weight functions not available with the F command. The number ### can be any value from .0000001 to 999999: however, care must be taken when using this command to ensure accurate results.
