Drift control (AutoRead)
The AutoRead function checks the stability of the measurement signal.
The stability has a considerable impact on the reproducibility of the
measured values.
When using a probe with integrated stirrer (StirrOx G), the
measurement with AutoRead can be started using the key on the
probe. As soon as a stable measured value is reached, the stirrer
switches itself off.
