5.1.3 Measuring the temperature
For reproducible ORP measurements, it is essential to measure the tempera-
ture of the test sample.
When operating a sensor without integrated temperature sensor, you first have
to measure and enter the temperature of the sample.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
mode:

ORP electrodes are not calibrated. You can, however, check ORP
electrodes by measuring the ORP of a test solution and comparing
the value with the nominal value.
