5 Connect the pH and redox measuring heads to the BNC connector at the positions
provided:
pH (left)
RX (right)
6 Start the filter pump.
7 Check the installation for leaks.
8 Stop the filter pump. Remove the electrodes from the holder and calibrate pH and redox
electrodes.
Attention!
(1) If you do not have a bypass configuration, you can insert two rubber caps (product code:
ZFPX4640 or fake probes ZWMX2067-Z) into the electrode holders to prevent water from
spraying out of the electrode holders during calibration.
(2) The electrode calibration procedure may take several minutes. To ensure an accurate
reading, it is important to follow the steps below carefully.
(3) Always ensure that the calibration fluids used in the calibration process match the
indicated values and that the fluids are not contaminated.
9 Calibration
Calibrate the electrodes
Using the following steps, you will have calibrated the electrodes in no time:
1.
Immerse the probes in the calibration liquids for pH (pH 7) and Redox (465-
468 mV) and wait 5 minutes to equilibrate before continuing with the
calibration process.
