ELECTRONIC SHUTTER
∙Using trigger pulse width
•Set DIP switches 1 to 4 on the rear panel to 0.
•An arbitrary shutter speed can be obtained by setting the trigger pulse width to the range of 2 μsec to 250 msec.

120 | μsec (CCIR) |
Note : 1. lt is recommended to set DIP switch 5 for field selection.
(The field selection is about two times in sensitivity as high as the frame selection.)
2.After a trigger pulse is input, a new trigger pulse must not be input before the video signal obtained by the trigger pulse has been output.
