Incrementally increase the kVp by 10 kV steps up to the tube's maximum rating (e.g., 125 kVp or 150 kVp). Allow a 30-second cooling interval between each exposure. Filament Current Calibration
Measure filament resistance at the tube head; check continuity of the low-voltage filament cables.
DRGEM generators feature advanced self-diagnostics that display specific error codes on the operator console or service software GUI when a fault occurs. Common Error Categories drgem x ray service manual
A standard DRGEM service manual is structured to guide a technician logically from installation through long-term maintenance. Installation & Set-Up
If the system is equipped with AEC (ion chambers), the service manual provides instructions on balancing the chambers. Technicians use acrylic phantoms to simulate different patient thicknesses, ensuring the AEC terminates the exposure at the exact optimal optical density or digital signal level. 4. Preventative Maintenance (PM) Checklist Incrementally increase the kVp by 10 kV steps
Inspect for oil leaks at the terminations; apply fresh silicone grease. Collimator Light
Changing parameters without consulting the manual can permanently damage the X-ray tube or create unsafe radiation doses. Always note the original values before making adjustments. apply fresh silicone grease.
The of the manual you need assistance interpreting (e.g., tube calibration, wiring diagrams)
The thermal switch inside the tube housing has tripped, requiring a cooling-down period before subsequent exposures are permitted. 6. Accessing DRGEM Service Manuals Safely and Legally
