Model 4.2i
3.5 Shutter
The
Mega Plus Camera may be operated with the shutter on or off. When the shutter is off, the
shutter blades can be locked open or closed. The shutter is controlled by the SHE command in
the CONTINUOUS, CONTROL and TRIGGER modes of operation. When the camera is set to
LINE operation, the shutter is controlled by the command line MC2.
When the shutter is on, the exposure time is set by the exposure command for both the
CONTINUOUS and TRIGGER modes of operation. When the camera is operated in the
CONTROL mode, the exposure lasts for as long as the EXPOSE input to the camera is “true”.
In general, the shutter should be turned off with the blades open if you are working in a darkened
area with a light source that is flashed. The camera is always gathering light even as an image is
being read from the sensor. If there is light on the subject between exposures, the shutter should
be used to prevent image smear. If you need to acquire a dark current frame, turn the shutter off
with the blades closed and transfer a frame.
