installed and free of corrosion or damage
• Check all electrical cabling and wiring for wear and fraying
• Check for any indications of oil leaking from the H.V. Tank
Perform Every Twelve Months:
• Verify accuracy of kVp, mA, and filament calibrations and, if
equipped, check AEC calibration (refer to Chapter 3,
CALIBRATION)
Use the Reproducibility, Linearity, and Maximum Deviation data test pro-
cedures and Calibration Data Sheets provided at the end of Chapter 3,
and verify that all calibrations are within specified tolerances as stated in
Chapter 2, SPECIFICATIONS; this is required to demonstrate compliance.
