Set Mode 3-Point / 2-Point / mAs + mA
Description:
The host requests that the set the unit to operate in 2-Point, 3
Point, or mAs+mA mode. (Note that 3-Point mode also called
manual mode).
In 3-Point mode the host programs the unit by specifying kV and
mA set-points, exposure time, filament size, and HSS Speed.
In 2-Point mode the host specifies the filament, kV set point and the
mAs (milliamp-seconds) for the exposure and the exposure mA,
exposure time and HSS Speed are automatically set based on
those. The exposure mA chosen will be the highest allowed mA for
the tube for the given filament and kV settings.
In mAs+mA mode the host programs the unit by specifying filament,
kV, mAs and mA. The exposure time is automatically determined
by those parameters.
IMPORTANT NOTE: Changing the modes does NOT change any
of the current exposure settings. The host should set 2-Point, 3-
Point or mAs+mA mode before programming the appropriate
exposure settings.
