The polarity of the input pulse can be set in the MENU options. In the
external mode the knob cannot be used to change the fl ash rate.
With no external input, the output jack ( pointing away from socket)
provides a TTL compatible pulse from the strobe’s internal oscillator.
If an external input is applied, the output pulse is in sync with the input
pulse. This output pulse may be used to trigger a second stroboscope
synchronously to illuminate larger areas. Many strobes can be “daisy
chained”. The output jack of one strobe is connected to the input jack of
the next strobe causing all the strobes to fl ash together and be controlled
by the fi rst strobe in the chain. The polarity of the output pulse can be
set in the MENU options.
3.0 LED STROBE OPERATION
3.1 Adjusting the Flash Rate - RPM
There are several ways to adjust the fl ash rate of the Strobe:
3.1.1 Using the Knob
The fl ash rate can be adjusted by turning the knob on the side of the
unit – counter clockwise to increase the fl ash rate and clockwise
to decrease the fl ash rate. The knob is rate sensitive, the faster you
turn the knob the greater the change in fl ash rate. The smallest
adjustment is to add or subtract one from the least signifi cant (right
most) digit on the display.
3.1.2 Using the Keypad
It is possible to enter the required fl ash rate as a number
by entering the value using the keypad as you would
with a calculator. Press the NUMber key shown right
followed by the numeric keys representing the fl ash
rate (eg 1234), using the secondary key functions –
numbers 0 to 9 and the period, then press the ENTER
