Combined calibration of pH and chlorine
It is mandatory that the pH measurement is always

calibrated first and then the chlorine measurement.

All other calibration of the pH measurement must

always be followed by calibration of the chlorine

measurement. Otherwise the chlorine measure‐

ment will be inaccurate.

Free chlorine or total available chlorine
Calibration of the zero point is not necessary.
Slope: Possible calibration in the range: 20% ...

300%.
A slope below 70% indicates a blockage of the dia‐

phragm. Refer to the operating instructions for your

sensor.
A slope of over 150% with sensors CLE3/CLE1

indicates surface-active components (surfactants)

in the sample water. Replacing the diaphragm only

delivers short-term improvement. It is important to

prevent the occurrence of surfactants in the water.

If surfactants cannot be avoided, then use an

appropriate sensor, for example sensor type CBR.
