4.11 Temperature compensation

We recommend the use of either a built-in or a separate temperature probe. If a temperature probe is
used, ATC and the sample temperature are displayed. If no temperature sensor is used, MTC is displayed
and the sample temperature should be entered manually. The meter accepts only an NTC 30 kΩ (pH)
and an NTC 22 kΩ (DO) temperature sensor.
The meter calculates the temperature-adjusted electrode slope using this temperature and shows the tem-
per a ture-compensated pH/ion value in the measurement display.

As soon as the measurement is stable according to the selected stability criterion, the Stability
icon appears.
