6)
Start the filter pump.
7)
Make sure that the installation has no water leakage.
8)
Stop the filter pump. Remove the electrodes from the holder and calibrate the pH and redox
electrodes.
Be careful!
(1)
(If you do not have a bypass configuration, you can place two rubber caps (product code:
ZFPX4640) in the electrode holders to prevent water from leaking from the electrode
holders during calibration.
(2)
If you have a bypass, make sure that the dosing pumps cannot pump liquid when the
bypass to the dosing nipples is closed. This can be done by switching off the dosing
pumps themselves or by switching off the power supply
(3)
Calibrating the electrodes may take a few minutes. For an accurate reading, it is
important to follow the steps below.
(4)
Ensure that the calibration fluids used in the calibration always correspond to the
specified values and that the liquids are not contaminated.
