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.

Conductivity of the reference solution
Explanation
Temperature input for automatic sensing of the test/
sample solution temperature during the calibration
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.
