Quality assurance of the results (DeviceCheck)
4.15.1
General information
The target of the analytical quality assurance (DeviceCheck) is to secure cor-
rect and precise measurement results.
The quality assurance measures can refer to two independent areas:
PCheck: Check of the photometer
MCheck: Test of the photometer and the method.
This test includes the photometer, the test used, the accessories, and the
user's method.
The monitoring includes a test run that must be repeated by the user suc-
cessfully within a certain period (interval).
DeviceCheck in the
measured value
documentation
All measured values that are measured after a passed test within the Device-
Check interval receive in the measured value documentation as addition the
Protocol ID
, via which the associated DeviceCheck test protocol can be iden-
tified. All measured values that are measured outside of the MCheck interval
receive as addition the entry "expired" in the measured value documentation.
4.15.2
Checking of photometer (PCheck)
For the photometer test, at least one test standard set is required, e.g. the
verification standard kit or a secondary standard kit with test certificate or
another commonly-used test tool (e.g. filter).
The administrator specifies which test standard has to be used as the mini-
mum requirement for the PCheck
monitoring.
The extent of the monitoring can be enlarged with further test standards.
Settings for DeviceCheck checks are only available for users of
the administrator user group.
The DeviceCheck test can be performed by any registered user
(see also Section 4.16.1).
As delivered from the factory, this monitoring is not switched on.
Settings for DeviceCheck checks are only available for users of
the administrator user group.
The DeviceCheck test can be performed by any registered user
(see also Section 4.16.1).
