Supporting test records reside with the manufacturer. The device
complies with Part 15 of the FCC Rules. Operation is subject to the
following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including
interference that may cause undesired operation.
General information
6

Changes or modifications to this equipment not expressly approved by
the party responsible for compliance could void the user's authority to
operate the equipment. This equipment has been tested and found to
comply with the limits for a Class A digital device, pursuant to Part
15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at their expense.
The following techniques can be used to reduce interference problems:
1. Move the equipment away from the device receiving the
interference.
2. Reposition the receiving antenna for the device receiving the
interference.
3. Try combinations of the above.

W A R N I N G
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.
The basic measurement steps necessary to run a test follow. Refer to
the applicable method to run a specific test.
1. Select the applicable measurement range or parameter. Refer to
Configure the instrument on page 13.
2. Prepare the blank according to the method document. Make sure to
use the correct sample cell size. Rinse the sample cell and cap with
the blank before the sample cell is filled.
13

3. Close the sample cell and clean the optical faces of the sample cell
with a lint-free cloth.
4. Insert the blank sample cell into the cell holder. Make sure to install
the blank sample cell in the correct and consistent orientation so
that the results are more repeatable and precise. Refer to Figure 6.
5. Install the instrument cap over the cell holder. Refer to Figure 7.
6. Push to set the instrument zero. The display shows "0.000", or
the degree of resolution that was previously selected.
7. Prepare the sample. Rinse the sample cell and cap with the sample
three times before the sample cell is filled. Add reagents as
specified by the method document.
8. Close the sample cell and clean the optical surfaces of the cell with
a lint-free cloth.
9. Insert the sample into the cell holder. Make sure to install the
sample cell in the correct and consistent orientation so that the
results are more repeatable and precise. Refer to Figure 6.
10. Install the instrument cap over the cell holder. Refer to Figure 7.
11. Push . The display shows the results in concentration units or
absorbance.
Note: The result flashes if the result is less or more than the instrument
range.

5.4 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 method 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 22.
5.4.1 Adjust the factory calibration with a standard
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 .
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. Push to enter the value of the standard. Push to go to the
next digit.
5. Push to add the standard calibration adjust value to the factory
calibration curve.
The calibration adjusted icon shows on the display. Refer to
Figure 5 on page 12.
Operation
17

5.4.2 Set the standard calibration adjust to off
To use the factory default calibration again, set standard calibration
adjust (SCA) to off.
1. Push .
2. Push until “SCA” shows, then push .
3. Push until "OFF" shows, then push .
Note: To set the SCA function to on again, calibrate with a standard.
5.5 User-entered calibration
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.
5.5.1 Channel restrictions
A user-entered calibration curve can be entered into any channel that
does not contain a factory-programmed curve. These channels have
the label:
• “abs” on the instruments that have a single factory calibration
