inconsistencies at specific techniques due to variations in tubes, cables, and
other factors. A technique is defined as a specific combination of kVp, mA,
and filament size. Advanced Filament Calibration is not required to achieve
satisfactory generator performance. It should only be performed on tech-
niques where mA accuracy improvement is required, or where mA waveform
optimization is desired. This tool is discussed immediately following the stan-
dard Filament Offset calibration procedure.
Access the Filament Calibration Menu (shown below) and proceed as follows:

WARNING! To avoid injury to personnel, ensure
system power is removed prior to making and
removing any electrical connections.
1. Factory Reset check box - when selected, will reset Filament Offset
Calibration values to factory default settings. This normally should not be
selected; it should only be selected when calibration values are extraordi-
narily out-of-range (usually signifying a hardware or software abnormal-
ity).
