* Please also note the operation manual for the respective sensor
7.6 Calibration of the Sensor for
Amperometric Measured
Variables
Only the slope can be calibrated in the
restricted operating menu of the
DULCOMETER ® D1Cb / D1Cc.
Both the zero point and the slope can be
calibrated in the complete operating menu
of the DULCOMETER
Condition
< 3 mA
(only with 4 - 20 mA sen‐
sors)
> 5 mA
> 6 mA for 0.5 ppm chlorite
® D1Cb / D1Cc.

the Sensors for Ampero‐
metric Measured Variables
CAUTION!
Correct sensor operation / Run-in
time
Damage to the product or its sur‐
roundings
– Correct measuring and dosing 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
allowed for when planning com‐
missioning
– It may take a whole working day
to run-in the sensor
