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.
