Chapter 1 Specifications
Revision W HF Series X-ray Generators - Service Manual
1-16 Quantum Medical Imaging
Refer to Table 1-6 for performance specifications of single-phase stored energy (SE) HF
Series Generators.
* Maximum exposure time is a function of kV and mAs settings and the age of the
batteries; Time measured at 75% of the peak kVp waveform
NOTE: AEC TECHNIQUES SHOULD HAVE EXPOSURE TIMES EXCEEDING 8
MILLISECONDS.
mAs is tube dependent; the generator may not reach maximum mAs due to tube type.
In AEC mode, the mAs is limited to 600.
