Not allowed -prohibited
Mandatory Must follow
DANGER
Do not use this product in an atmosphere
with risk of fire and/or explosion.

Do not look directly at the light emitting
section.
Failure to follow this could result in injury to the eyes.
CAUTION
Do not use and/or store the unit in the
Do not apply strong impact to the unit, or
drop it.
Failure to follow this could result in abnormal
operation.
Never disassemble, repair, and remodel
the unit.
Failure to follow this could result in injury due to
abnormal operation.
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 benzene,
thinner, or alcohol.
Since continuously emitting light for long time
causes the unit's housing to be very hot, fix
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.

Overview 1
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 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 non-contact and can be used to read the flash 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
Simply pressing the x2 or ÷2 key can change the emission count (frequency) to double or half
respectively
The emission time (duty) can be changed by 0.1º within the range between 0.1º/ to 3.6º/ 360º
The emission timing (phase) can be adjusted
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 4.3.4.1 Emission count setting for details
Refer to 4.3.4.2 Changing the emission count (frequency) to double or
half for details
Refer to 4.3.5 flash duration mode
Refer to 4.3.6 Phase mode for details

Charging (only for DT-365)2.3
Be sure to charge the battery before initial use. Before charging, be sure to check that the power is
turned OFF.
Charging method2.3.1
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.
Connect the supplied AC adapter
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.
Using another AC adapter than supplied.

Indication of low battery voltage2.3.2
If the remaining batter y 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 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 replacement2.3.3
If the fully charged battery continually decreases, please replace it with the specified replacement
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.
