Measuring
Overview of the measuring modes:
pH value
Special functions:
If you press <M> while pressing the <RUN/ENTER> key, the resolution
swaps between 0.01 and 0.001.
The AutoRead function checks the stability of the measurement signal (ex-
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>.
You can use pH electrodes with and without temperature sensors. The mea-
suring instrument recognizes which temperature sensors are connected and
switches automatically to the correct mode for the temperature measurement
(display TP).
Manual temperature input: Set the temperature value with < > < >.
