(approx. 33 l/h)
Clean or replace the preliminary fil-
ter.
Multi-sensor incorrectly connected
or defective.
Sample water flow rate insufficient
for some time (delay elapsed).
Zero ?
3-electrode measuring cell:
Sensor has zero current > +5 µA or
< -5 µA
Upot potential voltage set incor-
rectly; change, if necessary.
Electrodes of 3-electrode measuring
cell are dirty, if necessary clean /
service.
Sample water is not turned off or
check valve leaks; turn off sample
water, if necessary.

Sensor has zero current > +5 µA or
< -5 µA
Disinfectant in water, calibrate with
disinfectant-free water, if necessary.
