4.2.5 AutoRead AR (drift control) and hold function
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. With the aid of the hold function the
measured value display is frozen.
Use the AutoRead function and hold function like this:
Note
The current AutoRead measurement can be terminated at any time
(accepting the current value) by pressing <RUN/ENTER>.
1 Select the required measuring mode with <M>.
2 Activate the AutoRead function with <AR>.
The current measured value is frozen (hold function).
3 Start AutoRead with <RUN/ENTER>.
AR flashes until a stable measured value is reached.
4 If necessary, start the next AutoRead measurement with
<RUN/ENTER>.
5 To terminate AutoRead: Press the <AR> key.
