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.
