ERROR MESSAGES
Over Range
If the message OVERRANGE is displayed when scanning a sample, the
sample may be over range or under range. If the sample is over range, the
sample should be diluted and tested again (see Sample Dilution Techniques
and Volumetric Measurements, page 25).
If overrange is displayed, scroll to
Calibrate
and press
ENTER
to view
the result. The concentration is only
an

. Press

and
continue testing.

CALIBRATION
As with all pre-calibrated meters, it is highly recommended, even if not
required by regulations, that the user periodically verify the performance of
the meter by running standards with a predetermined concentration. Results
outside of specification are an indication that the meter needs to be adjusted.
This can be done following the user calibration described on page 10. If the
user calibration fails to properly adjust the meter then the meter should be
returned to LaMotte Company for recalibration. (See page 20).
STRAY LIGHT
The colorimeter should have no problems with stray light. Make sure that the
sample compartment lid is always fully closed.
