ACCEPTANCE TESTS (AEC)
This section applies only to generators with AEC.
•
Review chapter 3D: AEC Calibration.
•
Recheck the mAs, dose, and O.D. as recorded during initial installation. Follow the appropriate steps
in chapter 3D to verify the AEC calibration.

ACCEPTANCE TESTS (DR INTERFACE)
For CMP 200
®
DR X-ray generators with a DR imaging system, follow the system manufacturer’s
recommendations for system test to verify the DR interface.
