6.1.2 Measuring the temperature
For reproducible ORP measurements, it is essential to measure the tempera-
ture of the test sample.
You have the following options to measure the temperature:
Automatic measurement of the temperature by the temperature sensor
(NTC 30 or Pt 1000) integrated in electrode.
Measurement by an external temperature sensor.
Manual determination and input of the temperature.
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:
If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:

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.
