Caution: Certain tests require the production of X-rays. Field personnel should take
precautions to ensure their personal safety and the safety of others in close
proximity. Minimum precautions are as follows:
a. Wear lead aprons
b. Personnel remaining in the X-ray room during exposure should be behind a
lead shield
c. Minimize radiation scatter through doorways, walls and floor
X-RAY GENERATOR MAINTENANCE
The following list of items must be inspected during each preventive maintenance
inspection by qualified service personnel. Should other components become suspect
during the inspection, they also should be evaluated as necessary.
Item Explanation
Calibration
Verify the accuracy of kilovoltage, milliamp seconds, and
milliamperes. Calibrate as necessary.
Relays
Inspect electromechanical contactors and relays for pitting,
poor contact, loose or missing parts. Replace if necessary.
High Voltage
Transformer
a. Check transformer oil level. Proper oil level should be at
least ¾” (19mm) from the top of the circuit board but not
above the board. To replenish transformer oil, fill with
Diala-AX oil only.
b. Check electrical and mechanical connections of the
transformer. Clean and tighten as necessary.
High Voltage
Cables
Inspect high voltage cable bushings at the transformer and
rotating anode tube for signs of carbonization, tracking and
moisture. Replace the vapor proof compound every six
months.
Audible & Visual
Exposure
Indicators
Confirm that the audible indicator which indicates an X-ray
exposure, and the visual indicator, which indicates the
production of X-rays, are both functioning correctly.
