16  Calibrating Ci conductivity sensors 

The calibration default settings enable the calibration routines to be accessed in 
the particular calibration menu. 
Calibration routines that are not enabled are not visible in the calibration menu.
Additional calibration default settings are explained in the following table.

Calibration default settings for calibrating the relative cell constant

 Calibration default settings for calibrating the temperature coefficient

Temperature input for automatic sensing of the test/
sample solution temperature during the calibration

Reference tempera-
ture

-50 to 150 °C

The conductivities of a sample solution at the refer-
ence temperature and operation temperature are 
sensed during the calibration procedure. This yields 
2 value pairs (temperature/conductivity). These val-
ue pairs provide the basis for calculating the tem-
perature coefficient. 
The operation temp. must differ from the reference 
temperature by at least 5 °C.

Operating tempera-
ture

-50 to 150 °C
