(The trigger width should be between 2 s and 1/4 s)
3: The normal operation state is engaged when the trigger high period exceeds 1/3sec. The external trigger
*
shutter operation is engaged when the trigger pulse goes "low". In this case, the area between the falling
edge of a trigger pulse and the subsequent 50 ms period is an external trigger input inhibition area. During
the trigger inhibit period, an input trigger may be missed.
4: In all cases the WEN signal indicates when a valid image is available. Normally, an image is output after
*
the external falling edge. If the falling edge of the trigger is very close to the falling edge of the external VD,
there may be a delay of 1VD in the output. The period of uncertainty is when the falling edge of VD is
between 65 s before or 10 s after the falling edge of the trigger.
5: When the external trigger shutter mode changes into the normal operation mode, one WEN signal is
*
output.
Note
: An image is superimposed when the next exposure ends before the previous image is output.
