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.
