	(The effective trigger pulse width for the external

*3	The normal operation state is chosen when the
	trigger pulse width is 1/3 s or more. The trigger
	falling edge restores the external trigger shutter
	operation. 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. There is no guarantee of operation for any triggers input in this period.
