6.0 Operation
6.1 Aligning the unit and switching it on.
1. Point the stationary stroboscope at a moving object and
switch it on. The red LED inside the rocker switch indicates
that it is ready for use. If the LED lashes, the unit is
connected to the voltage supply but no trigger signal is
present. If the LED remains constantly lit, the unit is
receiving both voltage and a trigger signal.
2. As soon as the trigger signal is applied, the unit will start to lash with the trigger
frequency.
3. If the lashing frequency coincides with the movement frequency, a stationary
image will appear.
NOTE!
A stationary image will not only appear with an identical lashing frequency, but also
with multiples and fractions thereof.

two sockets to select which socket will be
used for the trigger signal input.
