kV Generation
Functional Tests
Make a Fluoro exposure and observe the kV readout on the control panel. The readout should remain steady on the desired kV
technique.
Perform the following tests to verify that the system is operating satisfactorily.
(Refer to the 9800 C-Arm Sub-system chapter of this manual for Functional Tests.)
1. System Boot
2. Make a fluoroscopic exposure.
3. Make a film exposure
Fault Isolation
WARNING: Dangerous voltages are present when covers are removed from the system and when
x-ray exposures are made.
Failure Possible Cause Remedy
Fluoro exposure technique
fluctuates or exhibits other
abnormalities
ABS not working, Video
Level unstable
Check the output connections from the Snubber PCB to the
IGBTs during a Fluoro exposure.
Using an extender card and oscilloscope, check the various
KVP control signals to determine which PCB may be faulty.
