The AutoRead function checks the stability of the measurement signal
(except for the measurement of the ORP voltage). Activate AutoRead with
<AR>
. Press
<RUN/ENTER>
to start the AutoRead measurement. During
the AutoRead measurement,
AR
flashes on the display until a stable
measured value is reached. This can be terminated at any time taking over
the current measured value with
<RUN/ENTER>
.
