The instrument shows clear messages when erroneous condition appears. Messages are also displayed
when the obtained values are outside expected range. The beeper is playing a beep on errors.
a) on calibration
Light High:
There is too much light to perform a measurement.
Please check the preparation of the calibration cuvette.
Light Low:
There is not enough light to perform a measurement.
Please check the preparation of the calibration cuvette.
ERRORS AND W
ARNINGS
No Light:
The instrument cannot adjust the light level. Please check
that the sample does not contain any debris.
Cal:
Calibration was not performed. Follow the instructions of the
measurement procedure for calibrating the meter.
b) on sample reading
Under range:
A blinking
“0.0”
indicates that the sample absorbs
less light than the zero reference. Check the procedure and make
sure you use the same cuvette for reference (calibration) and
measurement.
Over Range:
A flashing value of the maximum concentration
indicates an over range condition. The concentration of the sample
is beyond the programmed range: dilute the sample and re‑run
the test.
