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 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 the non-contact type, 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 that slightly move in order to observe their appearances.

Main features

The wide-range measurement of 60 fpm to120,000 fpm is available

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/360º and 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 trigger pulse, and enables the pulse signal in synchronization with the strobe emission to be output)

half" for details

2.3 Charging

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, and then the charging lamp goes off.

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 that emission and charging cannot be performed simultaneously.)

Note 3) 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 number display) to avoid reducing the battery life itself.

Note 4) If the unit is charged immediately after a long emission time 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, and start charging.

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

2.3.3 Battery replacement

CAUTION

When replacing the battery, be sure to turn off the stroboscope main unit. Do not touch the metal part of the connecter.

For a new battery, contact our dealer where you purchased this unit.

(1) Remove the four screws on both ends of the bottom of the DT-365E main unit, and take out the

built-in battery.

(2) Remove the connector and battery xing screws, and replace with a new battery. (3) Secure the new battery using xing screws and connect the connector to it.

(4) Mount the built-in battery in the main unit.

4.4.3.1 How to set the delay

External trigger pulse

(Pulse entered from an external device to DT-365E)

100ms（360°）

Emission

100ms（360°）

The delay angle from the pulse input to emission can be set by 0.1º within the range between 1º and 359º by setting one cycle of the external trigger pulse to 360º. Measure the external trigger pulse frequency per cycle, and calculate the delay angle based on the measured frequency to

perform the delay emission. Since a delay of approximately 20 μs always occurs for the internal

calculation, the actual delay time is calculated as follows:

Delay setting angle

360°

x External trigger pulse cycle + Approximately 20 μs

[Example 1] When setting the input frequency to 10 Hz (600 fpm), trigger edge to "rising",

and delay angle to 36º

Strobe emission

Frequency calculation

10ms（36°）

Delay

Frequency calculation

10ms（36°）

Delay Emission

• Since the delay angle is calculated based on the previously entered external trigger pulse cycle, if

the external trigger pulse frequency changes, emission cannot be performed at a precise angle. Also, since the external trigger pulse cycle becomes shorter than the previous pulse cycle, if the next external trigger pulse is entered before delay angle emission, the delay angle setting will be disabled, and emission is performed simultaneously(*) with the external trigger pulse.

• When the delay angle is set to 0º, emission is performed simultaneously(*) with the external

trigger pulse.

(*Since there is a delay caused by the internal calculation process, the strobe actually emits light in

approximately 20 μs after the external trigger pulse is entered.)

Turn the dial to the right to increase the delay angle setting value. Increasing the setting value from 359º will be 0º.

4.4.4 Saving the setting values

While using the unit while on internal oscillation emission and external synchronous emission, press the power switch and turn the power OFF to save the setting value to that which it was before turning the power OFF. When the power is turned ON again, operation starts from the previous setting value.

4.5.2 Measurement range setting (Function mode 1)

This function is used to set the measurement range on internal oscillation emission. The measurement range has two levels. The indicated contents depend on the measurement unit setting.

(Available setting range: 60.0 to 120,000)

* The emission count saved in the memory will be x10 or 1/10 by changing the measurement range.

Example: Save the emission count (frequency) of 6000 fpm in the range between 60 fpm and 120,000

fpm. After that, the saved value of the emission count (frequency) will be 600.0 fpm by changing the measurement range to between 60 fpm and 12,000 fpm.

* If the emission count (frequency) setting value is set to the one beyond (or below) the range when

changing the measurement range, the value will be limited to the maximum (or minimum) value within the range. Example 1: Save the emission count (frequency) of 60,000 fpm in the range between 60 fpm and

120,000 fpm. After that, the saved value of the emission count (frequency) will be 12,000.0 fpm by changing the measurement range to between 60 fpm and 12,000 fpm.

Example 2: Save the emission count (frequency) of 100 fpm in the range between 60 fpm and 120,000

fpm. After that, the saved value of the emission count (frequency) will be 60.0 fpm by changing the measurement range to between 60 fpm and 12,000 fpm.

Turn the dial to the CW direction to set the range to between "60 fpm and 12,000 fpm", and to the CCW direction to set the range to between "60 and 12,000". Operate the dial to stop the alternate display, and the only the measurement range setting value is indicated.

4.6.1 Interface specications

On the DT-365E main unit: Phone jack (φ3.5mm - 2 poles) Use the φ3.5mm 2-pole phone plug for

connection cables for input/output signals.

4.6.2 External trigger pulse input

Connect the unit to external devices (sensors, etc.) to allow the strobe to emit light using the pulse signal from the devices on external synchronous emission. (For details, refer to "4.4 External synchronous emission") * Since there is a delay caused by the internal calculation process, the strobe emits light in

approximately 20 μs after the external trigger pulse is entered.

Available input frequency : Available measurement range 40 to 35,000 fpm

Available delay emission range 60 to 10,000 fpm

Available input signal : NPN open collector signal

Available input pulse width : 50 μs or more

Available delay setting angle : within the range between 0 and 359º, available to set by 1º Available delay setting time :

within the range between 0 and 999 (max.) ms, available to set by 1 ms

4.6.3 External trigger pulse output

Output the signal to external devices simultaneously with emission while emission is performed in the internal oscillation mode or external trigger mode. * Since there is a delay caused by the internal calculation process, the signal is output in

approximately 10 μs after emission.
