Verification
The "Verification kit for AMI Photometer" is available as
an accessory. An optical window with a precisely deter-
mined absorbance value is placed into the light beam
of the photometer. The actual measured absorbance
will be compared to the reference value labeled on
each kit.
Prior to performing the verification the DPD reference value, e.g.
0.255, needs to be set in menu 5.1.4
<Installation>\<Sensors>\<Ref. Verification>.
Basically follow the dialog in menu 3.2.1
<Maintenance>\<Service>\<Verification>.
NOTICE: Start any time, if a measuring cycle is in progress wait
for next prompt.
1 Stop sample flow by closing regulating valve. Wait for next
prompt: Constant head will be drained and an automatic zero
will be defined.
2 Open cuvette of the photometer and insert the verification filter.
[Enter] to continue.
3 Align the triangle shape either to the front– or backside and ad-
just for minimal absorbance (see AMI Display).
4 Press [Enter] to save the verification measurement. The verifi-
cation is successful if the difference is within the limits. [Enter] to
continue.
5 Remove filter, close cuvette and open regulating valve. [Enter]
to finish and [Exit] to the main display.
Can be reviewed in menu 2.2.1.5

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.
