(3) MENU PHASE deg:

Delay setting between the trigger signal
and flash (in degrees relative to the
frequency
Phase sift (PHASE in deg)
Phase shift setting (in degrees, relative to the frequency) between the trigger signal and flash. This value
allows a fixed angle to be set between the trigger signal and flash.
• Example without external connection: The viewing position can be extremely precisely adjusted without
changing the flash frequency. You can shift the viewing position within a movement cycle.
• Example with external connection: The external trigger signal is triggered before the desired observation
point (= flash position of the stroboscope). This would mean that the connected stroboscope would
regularly flash too early. The PHASE deg setting adjusts the delay, altering the flash position of the
stroboscope by a set angle. This setting is not affected by the current rotational speed, which means that
the stroboscope will flash at the desired position even during rotational speed fluctuations or during the
start-up period.
