7.1.1 Preparing the calibration of the sensor for chlorine
CAUTION!
Correct sensor operation / Run-in time
Damage to the product or its surroundings
– Correct measuring and metering is only possible if
the sensor is working perfectly
–
Please read the operating manual for the sensor
– Please also read the operating manuals for the
fittings and other components used
– It is imperative that the run-in times of the sensors
are adhered to
– The run-in times should be allowed for when plan‐
ning initial operation
– It may take a whole working day to run-in the
sensor
Necessity of calibrating the zero point
Calibration of the zero point is not generally necessary.
Calibration of the zero point is only necessary if the
sensor is operated at the lower limit of the measuring
range or if the 0.5 ppm sensor version is used.
