ERROR MESSAGES

If the message OVERRANGE is displayed when scanning a sample, the

sample should be diluted and tested again (see Sample Dilution Techniques

to continue testing on
diluted samples.

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
speci cation are an indication that the meter needs to be adjusted. This can be
done following the user calibration described on page 28. If the user calibration
fails to properly adjust the meter then the meter should be returned to LaMotte
Company for recalibration. (See page 65).
STRAY LIGHT
The SMART3 Colorimeter should have no problems with stray light. Make sure
that the sample compartment lid is always fully closed, except when testing
COD with the adapter.
