17 Reopen the check valve on the sample water inlet and outlet
(pressurised version).
18 Perform the zero-point calibration after approximately three
hours running-in time.
Please note
You must calibrate each time the cell sand is replaced.
The calibration must be checked after one day.
Please note
We recommend checking and, if necessary, replacing the
electrodes and diaphragms when replacing the cell sand (see
“Replacing electrolyte, electrodes and diaphragms" on page 207).

Check electrolyte level
1 Check whether the potassium electrolyte is filled approx. 3 cm
over the water level (narrowing of the KCL container) and
replenish, if necessary.
To do this, remove the plug in the upper part of the electrolyte
tank and inject the electrolyte (use the syringe in the
accessory set).
2 The diaphragms in the electrolyte tank form the connection
between the reference electrolytes and the sample water. If
the sample water quality is poor (e.g. high iron content), both
diaphragms in the electrolyte housing should be replaced. The
diaphragms should be white (any coloration is an indication
that the diaphragms are clogged and should be replaced).
3 Calibrate after approximately three hours.
Please note
The calibration must be checked after one day.
