Troubleshooting AMX
Error Number
Filament-current table problem
Error Code / System Message
HIGH FIL LIMIT / LOW FIL LIMIT / FIL feedback errors
Error Question
How do I troubleshoot AMX-Series filament-current calibration limits?
Short Answer
The filament table is calibrated at specific kVp points and emission-current targets, with interpolation between calibrated points.
Possible Causes
Filament feedback calibration; table-point limit; tube aging; kVp feedback issue.
Troubleshooting Steps
Verify filament feedback, tube/cathode connections, kVp feedback and calibration points. Repeat the affected point and continue only after values stay within limits.
Parts Areas to Check
Filament circuit; X-ray tube; generator control
