tainer 2 with calibration solution.
When doing so gently move the

The controller displays the con‐
tinuous display again and oper‐
ates with the results of the cali‐
bration.
Incorrect calibration
Should the result of the cal‐
ibration lie outside the
specified tolerance limits,
an error message appears.
In this case the current cal‐
ibration will not be applied.
Check the prerequisites for
the calibration and clear
the error. Then repeat the
calibration

1-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
