Section 8 Calibration

This instrument is calibrated at the factory. No user calibration is necessary.

8.1 Standard calibration adjust

Use the standard calibration adjust (SCA) option when a calibration must be adjusted to meet regulatory requirements. The factory calibration is adjusted slightly with the standard calibration adjust (SCA) option so that the instrument shows the expected value of the standard solution. The adjusted calibration is then used for all test results. This adjustment can increase the test accuracy when there are slight variations in the reagents or instruments.
Note: For instruments with factory-calibrated ranges or methods, the standard calibration adjust (SCA) feature is disabled when a user-entered calibration is entered into the instrument. To set SCA back to on, set the instrument to the factory default calibration. Refer to Set to the factory default calibration on page 20.

8.1.1 Do a standard calibration adjust

1. Complete the test procedure for the range to calibrate. For the sample, use the standard solution concentration given in the test procedure documentation. Note: If a standard solution concentration is not given in the test procedure documentation, a different known standard can be used.

2. When the test procedure is completed, push and hold for 3 seconds.

3. Push until “SCA” shows, then push . The display shows the standard calibration adjust value.

4. If a different known standard is used, enter the value of the standard:
   a. Push until “Edit” shows, then push . b. Enter the value of the standard.
   Push the or to change the number that flashes. Push to go to the next digit. Push to go to the previous digit.

5. Push to add the standard calibration adjust value to the factory calibration curve.

8.1.2 Set the standard calibration adjust to off

To use the factory default calibration again, set standard calibration adjust (SCA) to off.

1. Push and hold for 3 seconds to enter menu mode.
2. Push until “SCA” shows, then push.
3. Push until “OFF” shows, then push.
   Note: To set the SCA function to on again, do a standard calibration adjust.

8.2 User-entered calibration curve

This instrument accepts a user-prepared calibration curve. The calibration curve can be from 0 to 2.5 absorbance. Make sure that the calibration curve includes standard values that are less and more than the range of interest. The instrument range will be the same as the calibration range. For example, when the standards that are used are 1.00, 2.00 and 4.00. The instrument range is 1.00 to 4.00.

There are two options to enter a user calibration curve: · Enter a calibration curve with standards–The standard solution
values are entered with the keypad and the absorbance values are measured. · Enter a calibration curve with the keypad–The standard solution values and absorbance values are entered with the keypad. Note: If the instrument is set to off or the instrument power is removed before a user-entered calibration curve is completed, the calibration curve is not saved. The instrument automatically switches off in user-entered calibration entry mode after 60 minutes of no activity. User-entered calibrations are completed when the user goes out of calibration (cal) mode or edit mode.

8.2.1 Enter a calibration curve with standards

Section 9 Maintenance CAUTION

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.
NOTICE
Do not disassemble the instrument for maintenance. If the internal components must be cleaned or repaired, contact the manufacturer.

9.1 Clean the instrument

Clean the exterior of the instrument with a moist cloth and a mild soap solution and then wipe the instrument dry as necessary. 9.2 Clean the sample cells
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets (MSDS/SDS) for safety protocols.
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and national regulations.

Most laboratory detergents are used at recommended concentrations. Neutral detergents, such as Liquinox, are safer to use when regular cleaning is necessary. To decrease the cleaning times, increase the temperature or use an ultrasonic bath. To complete the cleaning, rinse a few times with deionized water and then let the sample cell air dry. Sample cells may also be cleaned with acid, followed by a thorough rinse with deionized water. Note: Always use acid to clean sample cells that were used for low-level metal tests.
Special cleaning methods are necessary for individual procedures. When a brush is used to clean sample cells, take extra care to avoid scratches on the interior surfaces of the sample cells.

9.3 Replace the batteries

Replace the batteries when the battery power level is low. Refer to Install the batteries on page 7.
