13.3.2 Measuring ranges 1 to 4 for the CR input
Measuring range selection
On device versions with an IO-Link interface, the individual measuring ranges are activated by the IO-
Link master (PLC). The IO-Link master must be programmed appropriately by the user.

Temperature coefficient 0.0 to 8.0 %/K applicable only to "TC linear" and "TDS" compensation
The temperature coefficient is a measure of the temperature de-
pendence of the electrolytic conductivity of a liquid. It is used to
compensate for the effect of temperature when measuring the
electrolytic conductivity. If it is known, the temperature coeffi-
cient can be entered here or, if it is not yet known, determined
by the calibration.
