Calibration of
pH sensor
Process DIS
A-96.250.571 / 050517
Calibration
1 Calibrate pH sensor (if option pH is installed).
See
Standard pH, p.
2 Perform process calibration.
See
Process Calibration of DIS, p. 50
The instrument should be operating for 1h before performing a pH
calibration.
Program the two buffers you want to use for calibration (Installation/
Sensors/Standards). Calibrate the pH sensor with two buffers, e.g.
pH 7.00 and pH 9.00. See chapter
Let the instrument run for 1 h.
Use CHEMATEST 25 (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.

Questions and answers
Using the AMI Codes-II, there is Chlorine in the system, yet the system reads 0.00. Reseted, still no feedback. what could be the problem.
If the Swann AMI Codes-II system reads 0.00 for chlorine despite chlorine being present, possible issues could include:
1. Reagent Issues – The required reagents (OXYCON ON-LINE DPD, buffer solutions, etc.) might be depleted, expired, or improperly mixed.
2. Clogged or Dirty Components – The sample inlet, inlet filter, or flow regulating valve might be clogged, preventing proper water flow.
3. Calibration or Sensor Issues – The system may need recalibration, or the sensor might be faulty or improperly installed.
4. Power or Electrical Issues – The instrument may not be receiving proper power, or there could be an electrical fault affecting measurement.
5. Interference from Additives – Certain water additives like corrosion inhibitors or cyanuric acid might interfere with chlorine detection.
Checking reagent levels, cleaning components, recalibrating, and verifying power and water flow can help identify and resolve the issue.
