Material required for calibration of amperometric sensors:
n
A reference method suitable for the measured variable in ques‐
tion
Remove sample water directly at the measuring point and deter‐
mine the content of the feed chemical in the sample water in
[ppm]
using an appropriate reference method (e.g. DPD, titration etc.).
Enter this value into the controller as follows:
1.
Press in the continuous display.
2.
Use the arrow keys to select
[Slope calibration]
3.
Continue with
CAL Cl
A1044
Concentration
Latest sensor measured values
2) Take sample and continue with <CAL>
Sensor current
1) Wait until meas values stable
Fig. 33: Reference value calibration shows the actual sensor
values
4.
Continue with
CAL Cl
A1045
Measured value upon sampling
Change with <OK>
Determine reference value
continue with <CAL>
Fig. 34: Reference value calibration, the sensor value is frozen
here; now take the sample and measure using DPD, for example
5.
Then press to adjust the ppm value or press to con‐
tinue with the calibration
