For multiple exposures, you need to set up CYCLE and TIMES. CYCLE shows the time interval
between gates for multiple gating operation. TIMES sets the number of multiple exposures that are
possible.
・
GAIN
Sets to a voltage from 4.60 V down to 2.00 V. The lowest voltage varies by
the II being used. Default value is 4.6 0V (maximum).
・
WIDTH
Sets the gate width. It is changeable by 20 ns increment. The maximum
gate width is (CYCLE – 20) ns. Default value is 20 ns. It works in the gate
mode “GATING/DELAY”.
・
CYCLE
Setup item for multiple exposure operation. Default is 1/fps. It works in the
gate mode “GATING”.
・
TIMES
Sets the number of multiple exposures to be made. The number can only
be set if it matches the setting of CYCLE. It works in the gate mode
“GATING”.
・
DELEY
Sets the amount of delay when the gate mode is “DELAY”. It is
changeable by 20 ns increment. It works in the gate mode “DELAY”.

TIMES can be set from 1 up to 4.
When TIMES is set to 1, 2 or 3, the remaining pulses are
set to the zero level.
