Safety Requirements Be sure to observe

Before operation, maintenance and inspection, please carefully read this instruction manual and

follow it for proper use. Please carefully read all information related to this unit's safety precautions

before use.

This instruction manual provides two grades of safety warnings: Danger and Caution.

Each of them is an important description related to safety. Be sure to follow them.

DANGER This indicates the possibility of re, severe injury and even death if a user disregards the instruction

and operates the unit improperly.

CAUTION

This indicates a potential situation that could produce a minor injury or damage to material if it is

improperly handled.

However, depending on the circumstances, there could be a possibility that it may cause more

serious results. Be sure to follow them.

Protection categories are explained and separated by the following symbols

Not allowed -prohibited

Mandatory Must follow

DANGER

Do not use this product in an atmosphere

with risk of re and/or explosion.

Failure to follow this could result in re.

Do not look directly at the light emitting

section.

Failure to follow this could result in injury to the eyes.

CAUTION

Do not apply strong impact to the unit, or

drop it.

Failure to follow this could result in abnormal

operation.

Do not use and/or store the unit in the

following places.

•Where water may come in contact

•Where direct sunlight come in contact

•Where high humidity environment may be present

•Where dust, dirt, salt, and/or iron may be present

•Where oil, water, and/or chemicals come in contact

•Where a re or explosion may exist or occur.

Never disassemble, repair, and remodel

the unit.

Failure to follow this could result in injury due to

abnormal operation.

Use the unit within the proper operating

temperature range (32 - 104°

F).

Failure to follow this could result in malfunction.

Do not use any volatile chemicals, such as benzene,

thinner, or alcohol.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.

Since continuously emitting light for long time

causes the unit's housing to be very hot, x

the LED strobe using a tripod, etc. and use the

unit (avoid direct skin contact with the unit,

such as holding it by hand).

Failure to follow this could result in mild burns.

1 Overview

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theashcyclewhilethestrobeashisperiodically

applied on a rotating or moving object, the rotating (moving) object image appears to stand still. This

stroboscopetachometerisnon-contactandcanbeusedtoreadtheashfrequencywhensuchastill

image appears. Also, a stroboscope can be used to make images of rotating or moving objects stand

still or slightly move in order to observe their appearances.

Main features

Wide-range measurement of 60 to120,000 fpm

Refer to 4.3.4.1 Emission count setting for details



Simply pressing the x2 or ÷2 key can change the emission count (frequency) to double or half

respectively

Refer to 4.3.4.2 Changing the emission count (frequency) to double or

half for details

The emission time (duty) can be changed by 0.1º within the range between 0.1º/ 360º to 3.6º/ 360º

Refer to 4.3.5 ash duration mode for details

The emission timing (phase) can be adjusted

Refer to 4.3.6 Phase mode for details

The external I/O function is implemented which enables emission in synchronization with the external

pulse, and enables the pulse signal in synchronization with the strobe emission to be output.

Refer to 4.4 External synchronous emission for details

2.3 Charging (only for DT-365)

Be sure to charge the battery before initial use. Before charging, be sure to check that the power is

turned OFF.

2.3.1 Charging method

Turn the power OFF and connect the supplied 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 2.5 hours. Then the battery charging lamp turns off.

* Be sure to use only the supplied AC adapter.

When the power is turned ON with the supplied AC adapter connected, charging ends and

operation starts.

* Note that operation and charging cannot be performed simultaneously.

C onnect the sup p l ied A C adap ter

Note 1) Since the battery current is automatically shut off when charging is complete, there is no need

to worry about overcharging.

Note 2) 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 3) To extend battery life and charging capacity, it is recommended to deplete the battery fully

before charging. ( LLLLLL is indicated on the number display)

Note 4) If the unit is charged immediately after long periods of usage at a high ambient temperature,

the temperature rise protection 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 is

decreased, connect the AC adapter again to start charging.

Note 5) Never charge the unit under the following conditions.

2.3.2 Indication of low battery voltage

If the remaining battery power drops to near zero, the number display alternates between the

process setting and LLLLLL. However, operation can be performed even when the battery is in this

low condition.

If the remaining battery power decreases further, the number display indicates only LLLLLL, which

then stops operation. Press the power switch and shut off the power immediately.

In either case, charge the unit according to the procedure in 2.3.1 Charging method .

battery. Please contact your local dealer for details.

1. Remove 4 screws located on the bottom of DT-365 and take out the battery assembly.

2. Remove the screws on the connector and the battery supporter and replace with the new

battery.

3. Fix the new battery with the screws and connect the connector.

4. Install the new battery assembly to DT-365.
