Physically, the zero point of a new Redox probe is 0 mV.
This value can vary by +/- 25mV. During operation, the zero point changes in a positive or
negative direction. The zero point is recalculated during the next calibration. If the deviation
of the zero point e/- 58mV, the probe must not be used any longer. In case of a zero
point error, this error is displayed in the status display in the start menu.

/Calibration/Calibrate chlorine/ (example: chlorine)
Note:
The chlorine/chlorine dioxide/ozone probe must be checked periodically. To check the
probe, use a comparative measurement, e.g. according to the DPD method. If there are
deviations exc/- 0.10 mg/l, a calibration of the probe is required.
