Maintenance of the potentiostatic measurement
The metallic surfaces of the sensor are cleaned regularly and automatically by ASR. Mind that the
measurement will take some time to repolarise after cleaning.
Recalibrate if the difference between sensor output and photometric measurement is too large. Do not
calibrate immediately after cleaning.
NOTE
The instrument checks the calibration data and indicates if a sensor has to be cleaned or replaced.
If you have to exchange a sensor, make sure that the replacement sensor is an original KROHNE product
and that it corresponds to the equipment used.
Please mind that you have to calibrate whenever you change a sensor - or an instrument!
Regulary clean the flow cell and ensure free movement of the flow monitor.
To avoid causing an alarm in the central control system during maintenance on the instrument, the HOLD
mode can be selected. In that mode, the controller is OFF, the current output is fixed and the limit values are
deactivated. The HOLD mode is selected from the main display with key
just as the modes AUTO and
MAN.
