7.1.2 Measuring the temperature
For reproducible ion-selective measurements, it is essential to measure the
temperature of the test sample.
You have the following options to measure the temperature:
 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:
Increasing reproducibility also causes the response time to
increase until a measured value is evaluated as stable.

1. Measure the current temperature of the test sample.
2. When measuring without temperature sensor:
– Temper the test sample, or measure the current temperature.
