4 Wait for a stable measured value.
The AutoRead function (drift control) checks the stability of the mea-
surement signal. The stability has a considerable effect on the repro-
ducibility of the measured value.
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.
