INSTRUCTION MANUAL

1
Be sure to read the entire instruction manual thoroughly before initial set-up, operation and maintenance.
The instruction manual provides two grades of safety warnings: “Danger” and “Caution”.
Each of them is an important description related to safety. Be sure to observe.
This indicates the possibility of fire, severe injury, and even death if a user disregards the instruction
and operates the unit improperly.
This indicates the possibility of minor injury or property damage if a user operates the unit improperly.
However, depending on the circumstances, there is still the possibility that severe injury may result.
Be sure to observe.
We categorize the type of those precautions using the following symbols throughout the
manual.
A prohibited action you must not do.
A forced action you must always do.
Never use in flammable environments.
May result in fire.
Never look directly into the light source.
May result in eye injury
Do not apply strong impact to the unit,
or drop it.
Failure to follow this could result in abnormal
operation.
Avoid the followings.
Water, direct sunlight, condensation, dust, dirt, salt,
iron, oil, chemicals, corrosive and/or combustible
gases
Do not alter, modify or dispose improperly.
Failure to follow this could result in injury due to
abnormal operation.
Operate within 0-35°C(32-95°F)
Failure to follow this could result in malfunction.
Wipe clean the unit with a soft dry cloth if it gets dirty.
Or immerse a cloth in water diluted neutral detergent,
wring it, and wipe clean the unit with it.
Do not use any volatile chemicals, such as benzine,
thinner, or alcohol.
Operate within 35-85%RH
Failure to follow this could result in malfunction.
Since continuously emitting light for long time causes
the unit’s housing to heat up, fix the strobe using a
tripod, etc. (Avoid direct skin contact with the unit, such
as holding it by hand).
Failure to follow this could result in mild burns.

1 Overview of this product
A stroboscope tachometer is a measurement instrument to measure the speed (cycle) of rotating objects that rotate at a
constant speed, or moving objects that repeatedly operate at a constant cycle. When the rotation (motion) cycle matches with
the flash cycle while the strobe flash is periodically applied on a rotating or moving object, the rotating (moving) object image
appears to stand still. This stroboscope tachometer is the non-contact type, and can be used to read the object frequency when
such a still image appears. Also, a stroboscope can be used to make images of rotating or moving objects stand still or that
slightly move in order to observe their appearance in slow-motion.
Main features
●Wide flash range – 200 to 2500 FPM (flashes per minute)
●Emission in synchronization with the external trigger pulse
●Phase Shift function. (PHA mode)
●Sealed structure to prevent water and dust from entering.

② Dial (LAMP POWER)
Turn this clockwise or counterclockwise to change the emission frequency and some
setting value.
Press and hold the center of this to turn the lamp ON/OFF.
③ MODE
Press this to switch the LED display as follows
Flashes Per Minute mode (FPM mode)→Phase Shift mode (PHA mode DEG =
delay angle ) → Phase Shift mode ( PHA mode ms = delay time )→FPM mode →…
④ SIG
Select Internal/ External/ Parameter mode.
Internal oscillation emission (referred to as “INT” )：Flash by internal signal
External synchronous emission (referred to as “EXT”)：Synchronized flash with external
signal
⑤ DIV Press this while on EXT to change light emission cycle as follows
1/1⇒1/2⇒1/3⇒1/4⇒2/4. (Divided ratio)
⑥ SHIFT Press this while the emission frequency is divided to delay the emission timing by one
pulse.
⑦ ZERO
