Calibration of the measurement of Cl2, TCl2, ClO2, O3 and H2O2
1) Switch off the controller. Take a sample of the test water flowing out of the armature and determine the
concentration by photometric DPD measurement or a similar reference method.
2) Enter the determined concentration and calibrate by pressing keys
and : Start with key and then -
while still applying pressure on this key - additionally press key .
3) Check the displayed slope before switching on the controller.
