All Values are valid for 3-phase generator power line and large focal spot.
Values for other exposure conditions can be determined using the technical
data of the generator and the data sheets of the X-ray tubes.
In regular use these maximum exposure settings will not create doses that can
cause deterministic effects. Effective patient doses for typical exposures are
listed in Test Report for IEC 60601-1-3.
Note: The accuracy for exposure parameter settings complies to
EN IEC 60601-2-54 with absolute maximum of 10% for kV and
an absolute maximum of 20% for mA.

Radiographic Parameter Limits
Switching between small focus and large focus may have a delay of a few
seconds to enable the filament to warm up before switching.
The settings of kV and mAs or of mA and ms are defined by an algorithm. The
highest mA setting is used for which the kV can be reached by the system and
the exposure time is not lower than 1 ms or the mAs value is not lower than
0.5 mAs. When the kV setting is changed, the value of mA and ms are adjusted
automatically to keep the mAs value constant, within the boundaries of
generator or X-ray tube limitations.
If the radiographic parameters limits are reached, a value of a radiographic
parameter cannot be increased or decreased, or another value can be
automatically adjusted:
• Radiographic Parameters Limit. A maximum or minimum radiographic
parameter limit is reached. The value cannot be increased or decreased.
• Generator Power Limit. The generator power limit (kV x mA) is reached.
The value of the selected parameter cannot be increased. When increasing
the value of the other parameter, the value of the first parameter will
automatically be decreased to keep the mAs value constant.
