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.
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 B digital device, pursuant to Part

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.

Do a test
DANGER
Chemical or biological hazards. If this instrument is used to monitor a
treatment process and/or chemical feed system for which there are
regulatory limits and monitoring requirements related to public health,
public safety, food or beverage manufacture or processing, it is the
responsibility of the user of this instrument to know and abide by any
applicable regulation and to have sufficient and appropriate
mechanisms in place for compliance with applicable regulations in
the event of malfunction of the instrument.
DANGER
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.
The generic steps to do a test follow.
To do a test for a specific parameter (e.g., chlorine), download the test
procedure from the manufacturer's website. Refer to Download a test
procedure on page 14.
1. Push to select the applicable measurement range (e.g., LR or
HR).
2. Prepare the blank. Refer to the test procedure.
3. Clean the sample cell with a no-lint cloth.

Calibration
This instrument is calibrated at the factory. No user calibration is
necessary.
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.
English 15

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.
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.
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.
16 English

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.
