2-point fluoride sensor cali‐
bration (CAL)
Correct sensor operation
– Correct measuring and metering
is only possible if the sensor is
working perfectly
– Observe the sensor operating
instructions
– The carrying out of a 2-point cali‐
bration is strongly recommended
and is to be preferred to other
methods
– For calibration the sensor must
be removed and refitted in the in-
line probe housing. To do this,
observe the operating instructions
of your in-line probe housing
