AutoRead (drift
control)
The AutoRead function (drift control) continually checks the stability of the
measurement signal. The stability has a considerable impact on the repro-
ducibility of measured values. The display of the measured parameter flash-
es until a stable measured value is available.
Criteria
With identical measurement conditions, the following applies:
