Under Range: A blinking “0.00” indicates that the sample
absorbs less light than the zero reference. Check the procedure
and make sure you use the same cuvette for reference (zero) 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.
c) during calibration procedure
Standard Low: The standard reading is less than expected.
Standard High: The standard reading is higher than expected.
Cap error: Appears when external light enters in the analysis
cell. Assure that the cuvette cap is present.
d) other errors and warnings
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.
