4.4.0 ACCEPTANCE TESTS (kV, TIME, mA AND mAs) Cont
Step
8.
Select 75 kV.
Select the mAs shown below (2 point
operation).
Measure time at 75% of the peak kV
waveform.
A: 2 mAs (time per LCD display)
B: 8 mAs (time per LCD display)
C: 25 mAs (time per LCD display)
D: 63 mAs (time per LCD display)
9. Select 200 mA, 50 ms (3 point operation).
Select the kV values shown below.
Verify the actual kV per the RESULT column.
A: 50 kV
B: 60 kV
C: 80 kV
D: 100 kV
E: 125 kV
10. Select 75 kV, 50 ms (3 point operation).
Select the mA values shown below.
Measure mA at 75% of the peak kV waveform.
Verify the actual mA per the RESULT column.
A: 50 mA
B: 100 mA
C: 200 mA
D: 400 mA
4.5.0 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.
4.6.0 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.
