Overview of the measuring modes:
Special functions:
Select pH If you press <M> while pressing the <RUN/ENTER> key, the resolution
resolution swaps between 0.01 and 0.001.
AutoRead The AutoRead function checks the stability of the measurement signal (ex-
(drift control) cept 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 mea-
sured value is reached. This can be terminated at any time taking over the
current measured value with <RUN/ENTER>.
Temperature You can use pH electrodes with and without temperature sensors. The mea-
measurement suring instrument recognizes which temperature sensors are connected and
during pH switches automatically to the correct mode for the temperature measurement
measurements (display TF).
Manual temperature input: Set the temperature value with <A> <T>.
