Calibration data for ORP
sensor (CAL)
Correct sensor operation
– Correct measuring and metering
is only possible if the sensor is
working perfectly
– Refer to the sensor's operating
instructions
– Remove the sensor from the in-
line probe housing and re-fit it for
calibration. To do this, refer to the
operating instructions for your in-
line probe housing
ORP sensor calibration
The ORP sensor cannot be cali‐
brated. Only an ‘OFFSET’ deviation
of magnitude ± 40 mV can be set and
thus compensated. If the ORP sensor
deviates by more than ± 40 mV from
the reference value, then it must be
checked in accordance with the
requirements of the sensor operating
instructions.
