1.1 Modes of Operation
The stroboscope has two basic modes of operation – INTERNAL and
EXTERNAL. The unit does not operate when in the Charging Mode.
1.1.1 Internal Mode
The strobe is in the Internal Mode when nothing is plugged into the
input jack. In the internal mode the strobe generates its own timing
signals and the user can adjust the fl ash rate – see Section 3.1.
1.1.2 External Mode
In the External Input Mode the user can’t make any fl ash rate
adjustments. The fl ash rate is a function of the input signal. This
mode is used to synchronize the fl ash to an external event (for
example, from an optical sensor) to stop or freeze motion. The fl ash
will be triggered on the rising or falling edge (menu selectable) of
the external input pulse. The strobe is in the External Input Mode
