4. Verify that the X-ray tube's anode is rotating by listening for a "whirring" sound.
5. Verify operation of the vertical column lift switches.
6. Press and hold a FAST STOP switch while verifying that vertical column operation is disabled, then release the switch and
verify that X-ray generation is disabled and the message FAST STOP ACTIVATED is displayed on the C-Arm's Control
Panel display. Reboot the system by placing the Workstation's power switch in the OFF position for five seconds and then
back to ON.
7. Turn the C-Arm's keyswitch to the STANDBY position (counter-clockwise) and verify that vertical column operation is
disabled, X-ray generation is disabled and the message KEYSWITCH IN STANDBY - XRAYS AND LIFT DISABLED
scrolls across the C-Arm's Control Panel display.
8. Verify the ambient light sensor works by covering it and verifying that the monitor dims.
Line Voltage Regulation
WARNING
This procedure produces high energy X-rays. Take the appropriate precautions. Because of the
high radiation output produced, non-service personnel should not be present in the room during
the following test.
1. Measure the wall outlet voltage (Vn) or use the value measured in the Isolation Transformer Strapping procedure. Write the
measured value in the corresponding section of the Report/Checklist.
2. While taking a radiographic exposure at 100 kVp @ 300 mAs, measure the wall outlet voltage (Vl) again. Write the measured
value in the corresponding section of the Report/Checklist.
3. Use the following formula to calculate the percentage of line voltage regulation and record the result in the corresponding
section of the Report/Checklist.
Line Regulation =

= % Line Voltage Regulation
4. If the results above do not fall within the range of 0 - 15 %, note this in the Report/Checklist, and inform the hospital
administration that they will need to correct this problem. Note this also on the FSR or Case.
