The instrument shows clear messages when erroneous conditions appear. Messages are also displayed
when the obtained values are outside expected range. The beeper is playing a beep on errors.

Light High:
There is too much light to perform a measurement.
Please check the preparation of the zero cuvette.
Light Low:
There is not enough light to perform a measurement.
Please check the preparation of the zero cuvette.
No Light:
The instrument cannot adjust the light level. Please check
that the sample does not contain any debris.
Inverted cuvettes:
The sample and the zero cuvette are inverted.
Zero:
A zero reading was not taken. Follow the instructions of the
measurement procedure for zeroing the meter.
b) on sample reading

less light than the zero reference. Check the procedure and make sure
you use the same cuvette for reference (zero) and measurement.
