this, a stroboscope flash can be triggered at the desired position
even with fluctuating rotational speeds or when the system is
starting up.
DIV (pulse divider)
This function is only active with an external trigger signal. A value x
can be set with the pulse divider. The external trigger signal is then
divided by this value.
Example: An external trigger (e.g. rotational speed sensor) that
scans a gear wheel provides a signal with every tooth. With DIV
value = 10, a flash is only triggered with every 10th signal.
OPT
Edge selection of the trigger signal. 0 = positive edge , 1 = negative
edge. With this option, the polarity of the trigger signal can be
defined.
