2.9.1 Using the Test Stand for Over-Table Tubes
For over-table tubes, follow the assembly steps below and refer to Figure 2-4.
1. Remove the test stand from the case, slide the HVL filter tray up the test stand rod and position it
just below the rod's upper scribe mark. The scribe mark should align with the topside of the filter
tray. Tighten thumbscrew.
2. Slide the ion chamber holder up the test stand rod and position it just below the rod's center scribe
mark. The scribe mark should align with the topside of the ion chamber holder. Tighten
thumbscrew.
3. Place Model 96035B ion chamber in its holder and attach the triaxial cable. Route the cable down
the rod and secure it to the test stand near its base by snapping the wire cable clips around the rod.
Failure to secure the cable near the base of the test
stand may result in tipping the test stand and
damage to the equipment.
4. If not already in place, position the kVp divider on the test stand baseplate with filter pack facing
upward. Make sure the square rod is placed in the center hole on the holder as shown in Figure
2.4. The kVp divider’s rubber feet must be inserted fully into the half circle cutouts in the baseplate
for proper alignment.
Failure to properly align the kVp divider may result
in an incorrect kVp reading.
5. Place the test stand in an upright position
at the center of the x-ray beam.
6. Attach the interface cable to the kVp
divider. Route the cable around the side of
the instrument and secure it to the test
stand rod near the baseplate using the
attached cable clip.
7. Verify that both cables have been routed in
such a way that they will not interfere with
the x-ray beam as it travels to the ion
chamber and kVp divider.
