INSTRUCTION MANUAL

Safety Precautions

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.

DANGER : This indicates the possibility of fire, severe injury, and even death if a user disregards the instruction and operates the unit improperly.

CAUTION : 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.

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 – 30 to 35000 FPM(flashes per minute)
• Emission in synchronization with the external trigger pulse
• Phase Shift function.(PHA mode)
• Rechargeable

2. Before use

2.1 Checking the supplied items

Check that the five items below are supplied.

2.2 Charging

Be sure to charge the battery before initial use.
Before charging, be sure to check that the power is turned OFF.
Please check the state of the power switch OFF with the picture in “3.1 Main unit” on page 6.

2.2.1 Charging method

Turn the power OFF, and connect the AC adapter’s connector to the main unit.
Next insert the AC adapter’s AC plug into an outlet. The battery lamp lights up, and charging starts. Charging is complete in approximately 2 hours, and then the charging lamp goes off.

Be sure to use the supplied AC adapter.
Use at the ambient temperature 15°C or higher.
(If the ambient temperature is lower than 15°C, Charging may not be possible.)
*If the battery overheats, a charging error may occur.
In this case, let the internal temperature decrease and then reconnect the AC adapter.

Note 1) When the power is turned ON during charging, charging is canceled and emission starts. When the unit uses the AC adapter as its power source, it is not charged. (Note that emission and charging cannot be performed simultaneously.)

Note 2) Though the unit can be charged while battery power still remains, charging will still end when fully charged.

It is recommended, however, that the unit be charged when the battery has run out (“LLLLLL” is indicated on the display) to avoid reducing the battery life itself.

Note 3) If the unit is charged immediately after a long emission time at a high ambient temperature,the temperature detection circuit will turn on, and the charging lamp may not light up. In that case, disconnect the AC adapter, and let the unit cool. When the product temperature has decreased, connect the AC adapter again and start charging.

Note 4) Using in a high temperature environment may shorten the battery life.

4.11 Lamp replacement
The life of a xenon lamp is about 1200 hours when it is emitted at 1500 fpm each time. Although rotation speed is displayed, no flash is emitted. When the flash is intermittently emitted, this indicates the lamp must be replaced. Be sure to replace the lamp with the following steps. Be sure to use the specified lamp. Please contact us or the retailer where you purchased this product if you need it.
Be sure to turn the power OFF. May result in electric shock

The lamp is hot and may cause burns. After emission stops, let the stroboscope sit for 30 minutes or longer. Be sure stroboscope is cool to the touch before replacing the lamp.

Remove the protection window by loosening the 4 screws. Insert a thin screw driver into a hole of the protection window and pull out.
Remove the reflector and Insert the lamp insertion holder as far as it will go. Then turn it CW two or three times and pull out straight with lamp.
Be sure to use a lamp insertion holder. Pulling out lamp by hand may cause injury.

Insert new lamp into the lamp insertion holder with seeig the figure below. And press it to the socket in the proper direction.
Turn the lamp insertion holder CCW and pull out. And put carefully the reflector on the case properly.
Put the protection window back with 4 screws. *In order to maintain protection, be sure to fix the protective window. (Tightening torque: 0.3N-m or less)
