If the temperature change is greater than 2°C,
the message changes to

the message changes to
Calibrating the compact controller for inductive conductivity
Conductivity sensors with temperature element
You can only calibrate the temperature coefficient
with conductivity sensors with a temperature ele‐
ment, because it is impossible to calculate the tem‐
perature coefficient without measuring the tem‐
perature.
Temperature change
It is recommended that the temperature is changed
by no more than 0.5 °C per minute, or with a tem‐
perature change of e.g. 10 °C you will need to wait
for a minimum of 20 minutes before calibration.
