5.1.2 Measuring the temperature
For reproducible pH measurements, it is essential to measure the temperature
of the test sample.
You have the following options to measure the temperature:
 Automatic measurement of the temperature with the temperature sensor
(NTC30 or Pt1000) integrated in the sensor.
 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:
