9.1.10 Conductive
Temperature compensation and reference temperature
NOTICE!
The sensor must be dry
Do not allow the conductivity sensor to come into contact with liquid. Only allow the conduc‐
tivity sensor to come into contact with liquid once the conductivity sensor has been con‐
nected, configured and calibrated. The sensor parameters (zero point) of a moist or wet con‐
ductivity sensor can no longer be properly calibrated.
If the conductivity sensor has come into contact with liquid prior to calibration, there is an
option to dry the conductivity sensor. A dry conductivity sensor can be successfully recali‐
brated to the sensor parameters.
Set the temperature compensation and reference temperature for correct display of the conductive
conductivity and resistance.
Non-adjustable values are specified by the controller for the display of
