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:
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.
