*Random trigger shutter exposure delay time

In the random trigger shutter mode, there is an exposure delay time of approx. 2.6 µs from the falling edge of the TRIG signal to the start of exposure in both the FIX mode and pulse width mode.

*Pulse width mode exposure time

In the random trigger shutter and pulse width modes, the exposure time is determined depending on the pulse width, but the actual exposure time is pulse width + 8.6 µs.
