blinking.
Take remedial action as instructed below.

range)
A concentration of the

If the measured value of zero water is not abnormal, this trouble is out of
measurement range. No corrective action is possible.
The concentration of the
sample is low.

For clean water measurement, there is a possibility that the value is
negative. Perform zero calibration again.
