Incorrect calibration
Should the result of the calibration lie out‐
side the specified tolerance limits, an
error message appears. In this case the
current calibration will not be applied.
Check the prerequisites for the calibra‐
tion and clear the error. Then repeat the

Calibration of Amperometric Sensors
The calibration procedure for amperometric sen‐
sors is the same for all amperometric measured
variables.
The procedure for calibrating amperometric meas‐
ured variables is described throughout based on
the measured variable chlorine [Cl]. All other
measured variables require the same procedure as
the measured variable chlorine [Cl].
The following measured variables can be cali‐
brated using the procedure described here:
Chlorine
–
Chlorine dioxide
–
Bromine
–
Chlorite
–
Ozone
–
Peracetic acid (PES)
–
H O
