Explanation
Temperature input for automatic acquisition of the
test/sample solution temperature during the calibra-
tion
The conductivities of a sample solution at reference
temperature and working temperature are captured
during the calibration process. This yields 2 value
pairs (temperature/conductivity). These value pairs
provide the basis for calculating the temperature co-
efficient.
The operation temp. must differ from the reference
temperature by at least 5 °C.
