A zero reading was not taken. Follow the
instruction described in the measurement
procedures for zeroing the meter.
Under range. A blinking "0.00" indicates
that the sample absorbs less light than the
zero reference. Check the procedure and
make sure that you use the same cuvet for
reference (zero) and measurement.
1) 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 rerun the test.
2) A flashing value lower than the
maximum concentration indicates a low
signal-to-noise ratio condition. In this case
accuracy of the result is not guaranteed.
Repeat the reading procedure.
