7.3.1.2  Calibrating Amperometric Sensors

Calibrating Amperometric Sensors
The process for calibrating amperometric sensors

is identical with all amperometric measured varia‐

bles.
The process for calibrating amperometric meas‐

ured variables is described throughout based on

the measured variable chlorine [Cl]. All other

measured variables require the same process as

the measured variable chlorine [Cl].
The following measured variables can be cali‐

brated using the process described here:
–

Chlorine

–

Chlorine dioxide

–

Bromine

–

Chlorite

–

Ozone

–

Peracetic acid (PES)

–

H

2

O

Calibration combining pH and chlorine
It is imperative that you always calibrate the pH

measurement first before the chlorine measure‐

ment. The chlorine measurement always needs to

be calibrated any further time the pH measurement

is calibrated. Otherwise the chlorine measurement

will be inaccurate.

7.3.1.2.1  Selecting the calibration process for amperometric measured variables

There are two calibration processes available for calibrating the

controller:

n

Calibrating the slope

n

Calibrating the zero point
