Measuring

Overview of the measuring modes:
pH value
Special functions:
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>.
You can use pH electrodes with and without temperature sensors. The
measuring 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 < > < >.
