Calibration

1 Calibrate pH sensor (if option pH is installed).
See Standard pH, p.
2 Perform process calibration.
See Process Calibration of tc 2, p. 51
The instrument should be operating for 1h before performing a pH
calibration.
Let the instrument run for 1 h.
Use CHEMATEST (or equivalent photometer) to determine the
sample disinfectant concentration. Take the sample directly from
the flow cell. Determine the sample disinfectant value by 3 manual
DPD measurements. Calculate the average value. Compare this
value to the value, indicated by the AMI.
Keep in mind the accuracy of your manual measurement. Only cor-
rect the instrument if the difference is significant.
Perform process DIS if necessary. See chapter
for details.
