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]
