Quality Control; Performing Optical Quality Control - Accriva Diagnostic AVOXimeter 4000 Operator's Manual

Quality Control

Routine quality control testing should be part of a comprehensive quality assurance program.
Quality control testing of the AVOXimeter 4000 consists of the following operations:
●
Daily optical quality control.
●
Weekly testing of one level of liquid controls.
In addition, the AVOXimeter 4000 performs a "self-check" to verify that the light source is
operating properly every time it is turned on.
Note: If quality control results are out of range, refer to the Troubleshooting section for
instructions. If the "self-check" fails, contact Technical Support (see page ii).

Performing Optical Quality Control

The yellow and orange optical filters supplied with the AVOXimeter 4000 provide a convenient
means of verifying that the optics are not obscured by blood or debris and that the instrument is
properly calibrated. Each filter simulates a cuvette containing a blood sample of known
composition and has a serial number that matches the serial number of the instrument.
CAUTION: Each filter is labeled with a serial number that matches the serial number
of the instrument. Verify that the serial number on each filter matches the serial
number of the instrument when performing optical quality control. Each set of yellow
and orange filters can only be used only with the AVOXimeter 4000 of the same serial
number and cannot be shared between different instruments.

Cuvette" screen is displayed:
