When the strobe is powered up, it will begin flashing immediately. It will
remember the last internal flash rate and whether to display in FPM or FPS.
The back panel consists
of a backlighted liquid
crystal display with six
which indicate modes,
flash rates, etc. (Fig 3).
Below the six digits are
five small chevrons (#)
which indicate the
present mode or value
currently indicated - Ext
(External mode), Tach,
Alt function, FPS (
Flashes Per Second),
and FPM (Flashes Per
Minute). The External
Chevron is on whenever
the strobe is in the
external mode. That is
when it has an external
signal plugged into the
external input jack. The Tachometer chevron is on whenever the tachometer
only (no flashing) mode is selected. The Alt Function chevron toggles
whenever the Alt function button is pressed. When this chevron is on, the
buttons will perform their alternate function listed in the white (lower) section
of each button. The FPS chevron is on when the display is displaying Flashes
Per Second or Hertz (Hz). FPS = FPM ÷ 60. The FPM chevron is on when
the display is displaying Flashes Per Minute.
Below the display are six membrane buttons which control the operation of
There are three major operating modes for the Strobe. These are Internal,
External and Charging (Battery powered model only). In the Internal mode,
the knob adjusts the flash rate from 30 to 14,000 Flashes Per Minute (FPM).
In the External mode, an external signal from a remote sensor is used to
trigger the flash and the knob has no effect. The Charging mode (Battery
powered model only) is when the strobe has the battery charger plugged
into it. The strobe will continuously display the state of the battery charge
while being recharged.
In instances when you can shut down the device and install a piece of
reflective tape then an optical tachometer is easier to use for RPM
measurement. Stroboscopes must be used when you can’t shut down
the device. The human eye is not easily tricked into seeing a stopped image
by a stroboscope when the flash rate is slower than 300 FPM. Therefore,
stroboscopes are just about impossible to use below 300 FPM for inspection
or to measure RPM.
5.1 Lamp Replacement
The replacement of the lamp can be accomplished by using only a

BEFORE ATTEMPTING TO REMOVE THE LAMP MAKE SURE THE
STROBOSCOPE IS TURNED OFF AND ANY MAINS CORD
REMOVED FROM THE AC OUTLET. ALLOW THE LAMP TO COOL
BUT WAIT AT LEAST 1 MINUTE BEFORE ATTEMPTING TO
CHANGE THE LAMP.
The stroboscope is designed to discharge the internal high voltages
within 30 seconds. However, caution should be exercised when replacing
To change the lamp it is necessary only to remove the front lens. The
lens is held in place by two tabs on the sides of the reflector housing.
These must be pushed apart and the lens removed. A small screwdriver
can be used to help pry one tab and lift the lens. Take care not to pry
the tab any more than is necessary to free the lens. The reflector is held
in place by the front lens and will come loose. It is not necessary however
to remove the reflector. The lamp should be held with a cloth between
forefinger and thumb and rocked gently while pulling out. Do not attempt
to rotate the lamp. The lamp is socketed and will come out easily when
DO NOT TOUCH THE NEW LAMP WITH BARE FINGERS. The new
lamp is fitted by locating the plug pins into the socket. The lamps are
polarized. Using a lint free cloth, match up the red dot on the plug
with the red dot on the socket and gently rock the lamp while pushing
it into place. Make sure the lamp is in straight and centered in the reflector
hole. Caution - Do NOT allow the reflector to contact the lamp.
Reinstall the reflector and then position the front lens in place. Position
