4.15.2 Photometer monitoring (AQA1)
At least one set of test standards such as Spectroquant
®
PhotoCheck or Cer-
tiPUR
®
is required for the photometer monitoring.
The administrator specifies which test standard has to be used as the mini-
mum requirement for the AQA1 monitoring.
The extent of the monitoring can be enlarged with further test standards.
Note
Settings for AQA checks are only available for users of the user group,

PhotoCheck
The PhotoCheck consists of 12 test standards in duplicate, 2 zero cells and
2 cells to check the barcode reader. Each PhotoCheck package contains a
lot dependent test certificate with all nominal values (absorbances) and toler-
ances of the test standards. These values are entered in the photometer dur-
ing the configuration of the AQA1 check.
CertiPUR

test
standards
Each CertiPUR
®
standard is provided with a lot dependent test certificate
with all nominal values (absorbances) and tolerances of the test standards.
The values were preset in the factory.
Note
Observe the shelf life of the test standards. The values in the photometer
always have to be checked when a new package of test standard is used. If
necessary, adjust the values at the photometer.
