Verification
The "Verification kit for AMI Photometer" is available as an
accessory. An optical window with a precisely determined
absorbance value is placed into the light beam of the pho-
tometer. The actual measured absorbance will be compared
to the reference value labeled on each kit.
Prior to performing a verification the reference value, e.g. 0.255,
needs to be set in menu 5.1.1 (Installation\Sensors\Ref. Verifica-
tion).
Navigate to the menu 3.2.1 (Maintenance\Service\Verification) and
follow the dialog on the screen.
Note: 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 Unscrew the cover from the photometer.
3 Insert the verification filter.
4 Press <Enter> to continue.
5 Align the triangle shape either to the front– or backside and ad-
just for minimal absorbance (see AMI Display).
6 Press <Enter> to save the verification measurement. The verifi-
cation is successful if the difference is within the limits. <Enter>
to continue.
7 Remove filter, close the photometer and open regulating valve.
<Enter> to finish and <Exit> to the main display.
