General Instructions
NOTICE: The sample for the manual measurement (with DPD)
must be taken directly from the flow cell.
If you need further help please contact your dealer. Note serial
number of instrument and all diagnostic values before doing so.
Zero photometry: 10'000–16'000 Hz (mostly near 16 000 Hz)
Slope photometry: 0.8–1.2
pH offset: New pH sensor: near 0, old pH sensor 50 mV
pH slope: typically: 55–62 mV/pH unit.
Problem

Possible Reasons
Sample taken too close to feeding line
Sample flow too irregular or too low
Wrong manual measurement or old
chemicals have been used. Repeat the
verification.
Reagents of AMI Codes mixed wrongly or
not completely
Check sample flow at photometer outlet.
It must be at least 100 ml/min. For that
place the photometer outlet tube into a
measuring cup for 1 minute.
Check sample line for pressure
fluctuation.
Check for regular air bubble pattern.
Check flow alarm values in menu

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.
