This is when the probe must be rinsed with sampling water. Once this has taken place
the calibration can be continued through operating ENTER.
Measuring value
indication
The current electrometric-measuring signal is then displayed on the screen.
The calibration can be finished through selecting the interrupt calibration option, which
also opens the calibration module selection menu.
If the measured value is stable, it can be saved with the measuring store option and the
calibration process can then be continued.
ClO -concentration
2
Now the measuring signal must be allocated in mV to the ClO
specified in mg/l.
In order to do so, the (possibly established according to the DPD1-Methode) ClO
concentration for the above saved measuring signal must be entered in the ClO
concentration line.
The go on function saves the allocation and the calibration process continues.
Mutual conductance
The calculated mutual conductance of the ClO
of the ClO measurement module calibration.

The calibration is completed through operating go on, which also opens the calibration
module selection menu.
NOTE
417101816_Anhang09_ClO2.doc
The calibration is completed in due order if the calculated mutual conductance is
between 300 mV/mg/l and 3000 mV/mg/l. All other cases signify a mutual
conductance error. Although measuring can be continued within limits, the reasons
for the mutual conductance errors should be established and corrected if
necessary.
