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

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
