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.
Replace the batteries
W A R N I N G
Explosion hazard. Expired batteries can cause hydrogen gas buildup inside the instrument. Replace
the batteries before they expire and do not store the instrument for long periods with the batteries
installed.

Troubleshooting
Problem
Possible cause
Solution
Absorbance > 3.5!
The measured absorbance is more than 3.5.
Dilute the sample and repeat the
reading.
Over range!
The concentration is more than the upper limit
of the current method.
Dilute the sample and repeat the
reading.
Under range!
The concentration is less than the lower limit of
the current method.
Examine the sample.
Reading Failed!
There is an electronic or optical defect.
Contact technical support.
Initializing Failed!
While initializing, the instrument failed.
Set the instrument to off and then
to on.
Contact technical support.
