3.4 ANODE ROTATION TEST
Perform the following tests for each X-ray Tube in the installation, checking the
low and high speed when it is required.
Two people are needed for these tests, one at the Console and the
service engineer looking at the anode of the X-ray Tube. These
tests also can be done by hearing the sound of the anode rotating.
NEVER MAKE EXPOSURES DURING THE TESTS, THE
PERSON CLOSE TO THE X-RAY TUBE WILL BE EXPOSED.
1. With the switch 3024SW2-3 on the ATP Console CPU Board in “On”
position (service mode), turn the Console ON and select the
corresponding X-ray Tube.
2. Select a low value for kVp and mAs for checking the Anode Rotation at
Low Speed.
3. Press the “Prep” push-button and visually check that the Tube anode
rotates in the proper way. (Refer to the X-ray Tube documentation).
4. Hold pressed the “Prep” push-button and check that the rotation speed
of the Tube anode is in compliance with the X-ray Tube specifications.
For this test is recommended to turn off the Tube filaments (switch
3000SW2-2 on the HT Controller in “On” position) and use a stroboscope
to measure the anode speed.
5. Release the “Prep” push-button.
6. For Generators with LV-DRAC, select a high value for kVp and mAs for
checking the Anode Rotation at High Speed. Repeat steps 3, 4 and 5.
7. If required for the second Tube, repeat this procedure.
