4.4.4 AutoRead AR (Drift control)
The AutoRead function (drift control) checks the stability of the mea-
surement signal. The stability has a considerable impact on the repro-
ducibility of the measured values.
Criteria With identical measurement conditions, the following applies:
1 Call up the measuring mode with <M> and/or <> <> .
2 Activate the AutoRead function with <AR>. The current mea-
sured value is frozen (hold function).
3 Start AutoRead with <RUN/ENTER>.
AR flashes until a stable measured value is reached. This mea-
sured value is transmitted to the interface.
4 If necessary, start the next AutoRead measurement with
<RUN/ENTER>.
5 To terminate the AutoRead function: Press the <AR> key.
