The [AR] status indicator appears while the measured value is assessed
as not stable. A progress bar is displayed and the display of the mea-
sured parameter flashes.
The [HOLD][AR] status indicator appears as soon as a stable measured
value is recognized. The progress bar disappears, the display of the mea-
sured parameter stops flashing, and there is a beep.
The current measurement data is output to the interface. Measurement
data meeting the stability control criterion is marked by AR.

The Stability control function checks whether the measured values are stable
within the monitored time interval.
Measured Time interval

The minimum duration until a measured value is assessed as stable is the
monitored time interval. The actual duration is mostly longer.

5.1.2 Measuring the temperature

For reproducible pH measurements, it is essential to measure the temperature
of the test sample.
IDS sensors measure the temperature with a temperature sensor integrated in
the IDS sensor.
