1.2 Modes of Operation
The stroboscope has two basic modes of operation – INTERNAL and
EXTERNAL.
1.2.1 Internal Mode
The strobe is in the Internal Mode when nothing is plugged into the
input jack or when manually set using the
INPUT
button. In the
internal mode the strobe generates its own timing signals and the
users can enter the flash rate using several different methods – see
Section 3.1.
1.2.2 External Mode
In the External Input Mode the user can’t make any flash rate
adjustments with the knob. The flash rate is a function of the input
signal. This mode is used to synchronize the flash to an external event
(for example, from an optical sensor) to stop or freeze motion. The
flash will be triggered on the rising or falling edge (menu selectable)
of the external input pulse. The strobe is in the External Input Mode
whenever there is a plug in the input jack. When the strobe is in the
External Input Mode,
EXT
will be displayed.
When an external input is applied to the unit and the strobe is put in the
Tachometer Mode, the unit will read the signal from the external input
(sensor) and display the reading on the LCD display without flashing
the lamp.
The strobe will not flash in the Tach (Tachometer) Mode.
1.2.3 Charging Mode
The
Charging Mode
is when the strobe has the battery recharger
plugged into it. The strobe will continuously display the state of the
battery charge while being recharged.
