Chapter 1 Specifications
HF Series X-ray Generators - Service Manual Revision W
Quantum Medical Imaging 1-17
Refer to Table 1-7 for performance specifications of three-phase HF Series Gener-
ators.
* 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.
High-Speed Starter Duty Cycle: do not to exceed two activations
within any one minute period
