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 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
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.

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.

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.

Emission duration mode4.3.5
The emission time (ratio) can be set by 0.1º within the range between 0.1º/ 360º and 3.6º/ 360º in the emission duration mode (DUR). The emission time setting value shows the strobe emitting time by angle while a rotating object rotates one revolution (360º). While the “UNIT” key is being pressed, the value converted from the emission angle to time can be checked. A longer emission time increases the brightness, but a measured object appears to be moving. Also, a shorter emission time decreases the brightness, but a measured object appears to stand more still. Adjust the appropriate emission time according to your application and conditions and use the unit. Press the MODE key to switch to the phase mode (PHA).

How to set the delay4.4.3.1
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 pulse to 360º. Measure the external pulse frequency per cycle, and calculate the delay angle based on the measured frequency to perform the delay emission. Since a delay of approximately 30 μs always exists for the internal calculation, the actual delay time is calculated as follows:
Delay setting angle
360°
× External pulse cycle + Approximately 30 μs
[Example 1] When setting the input frequency to 10 Hz (600 fpm), trigger edge to rising, and
delay angle to 36º

Delay
emission
* When the delay unit is set to ms in the above example, the delay time can be set within the time range
of less than one cycle input pulse (0 ms to 99 ms).
• Since the delay angle is calculated based on the previously entered pulse cycle, if the external
pulse frequency changes, emission cannot be performed at a precise angle. Also, since the external pulse cycle becomes shorter than the previous pulse cycle, if the next pulse is entered before delay angle emission, the delay angle setting will be disabled, and emission is performed simultaneously* with the external pulse.
•When the delay angle is set to 0º, emission is performed simultaneously with the external pulse.
* Since there is a delay caused by the internal calculation process, the strobe actually emits light in
approximately 30 μs after the external 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.

Measurement range setting (Function mode 1)4.6.2
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.
Measurement unit *Measurement range
fpm
* 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.

Auto emission stop time setting (Function mode 3)4.6.4
This setting is used to stop the emission automatically when no operation is performed for a certain period of time. The available setting time is within the range between 0 min and 120 min, which can be changed by 1 minute. When it is set to 0, the auto emission stop function is turned OFF and emission is performed continuously. When emission is stopped by the auto emission stop function, use the key or dial operations to restart emission.
