There are two calibration processes avail‐
able for calibrating the controller:
Calibrating the slope
n
Calibrating the zero point

Calibrating the slope
CAUTION!
Correct sensor operation / Run-in
period
Damage to the product or its sur‐
roundings
–
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
periods of the sensors are
adhered to
–
The run in periods should be
A1039
allowed for when planning com‐
missioning
–
It may take an entire working day
to run in the sensor
