10.1.2 2-Point Calibration of the
pH Sensor (CAL)
Correct sensor operation
–
Correct measuring and metering is
only possible if the sensor is
working perfectly.
–
Refer to the sensor's operating
instructions.
–
2-point calibration is strongly rec‐
ommended and is preferable to
other methods.
–
The sensor needs to be removed
and refitted in the in-line probe
housing for calibration. Refer to
the operating instructions for your
in-line probe housing.
