11.1.7 Unit and format
11.1.8 Temperature compensation
Temperature coefficient = change in the conductivity per degree of temperature change:
(T) = (T
0
)(1 + (T - T
0
))
(T) ... conductivity at process temperature T
(T
0
) ... conductivity at reference temperature T
0
The temperature coefficient depends both on the chemical composition of the solution and the
temperature itself.

The picklist depends on the operating mode.
You can either choose from units for conductivity or
units for resistivity.
Since there are no options for concentration
measurement, this function is not displayed for such
measurements.

Decide how you want to compensate the medium tem-
perature:
• Automatically using the temperature sensor of your
sensor
• Manually by entering the medium temperature
