The cable must be replaced if it has been penetrated by rust or corrosion.
(4) Move the spot-film device to its lowest possible position to inspect a third
cable attached to the counterweight holder at the center bottom. Inspect for kinks,
strand separation, rust, and corrosion as above.
Inspect the internal printed-circuit boards (PCBs) for the following.
(b) Loose or missing components.
Replace all covers after inspecting the cables.
f. Inspect the Collimator.
This step is performed annually.
Inspect the exterior surfaces for damage, rust, and corrosion.
Inspect the cables and connectors for tightness and insulation breaks.
(3) Inspect the carrying frame and collimator X-ray tube for missing parts,
rust, and corrosion.
g. Perform a Function Check.
The procedure in this section requires the making of exposures. Take
all precautions necessary to protect all personnel against unnecessary
Select the over-table X-ray tube.
(a) Set the machine at 80kvp, 200ma and 0.1 seconds. Make four
exposures at 20-second intervals.
(b) Make four additional exposures at 20-second intervals, increasing
the kvp by 10kvp for each exposure. Begin the exposures at 90kvp.
