Calibration Errors
Process calibration DIS
Slope error:
Possible cause
Wrong manual measure-
ment.
Wrong reagent mixture
Reagents not
completely solved in
water.
Process pH
Offset error:
Possible cause
Manual measurement
wrong.
Slope of last calibration
wrong.
pH sensor dirty, old or
defect.
Cable connector corroded.
Standard pH
Offset error or Slope error:
Possible cause
Old, dirty or wrong buffer
solutions.
Verify programmed buffer
values with the values of
the buffer solution used.
pH sensor dirty, old or
defect.
Cable connector corroded.
Corrective Action
Repeat the manual measurement.
Use fresh reagents.
Make a correct mixture.
Mix long and intensively.
Corrective Action
Repeat the manual measurement.
Set default calibration values, see
5.4.2, p.
94.
Repeat the calibration
Clean or replace pH sensor, see
Maintenance of pH sensor, p.
Replace cable and sensor.
Corrective Action
Check buffers expiration date if
necessary order new buffer.
Change programmed buffer values
or use correct buffer solution.
Clean or replace pH sensor, see
Maintenance of pH sensor, p.
Replace cable and sensor.

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.
