2. คุณสมบัติหลัก
- การวัดอเนกประสงค์: Measures rotational speed and inspects surface defects without contact or stopping the object.
- การให้แสงสว่างที่สดใส: Utilizes a xenon lamp for very bright illumination, enabling operation in room light conditions and at long distances. The flash rate is adjustable.
- Multiple Observation Modes: Provides images of single stillness, two stillness, or multiple stillness for vibrating, rapidly rolling, or periodically moving objects. Also observes movement tracks for detailed analysis.
- Non-contact Operation: Allows measurement and inspection without stopping machinery or attaching reflective marks, offering a convenient and efficient solution.
- ความแม่นยำสูง: Features a measurement range of 50~12,000 FPM, a 5-digit, 10mm (0.4") LCD display, high accuracy, and fast sampling time (0.3 seconds).
- Durable Flash Tube: The xenon flash tube has a long life of 100 million flashes, with a flash timer for conservation.
- อินเทอร์เฟซที่เป็นมิตรกับผู้ใช้: Equipped with external triggering capability and an easy-to-read LCD screen for instant, clear, and legible results, ensuring high resolution and exact readings.

4. การตั้งค่า
4.1 การเปิด/ปิดเครื่อง
To power on the stroboscope, press and hold the power button (usually marked with a circle and a vertical line) for approximately 3 seconds. The LCD screen will illuminate, indicating the device is ready for use. To power off, press and hold the same button until the display turns off.
4.2 การตรวจสอบเบื้องต้น
Before first use, inspect the device for any visible damage. Ensure the xenon lamp is securely in place. If a spare lamp is needed, refer to the maintenance section for replacement instructions.

5. คู่มือการใช้งาน
5.1 ทำความเข้าใจกับจอแสดงผล
The stroboscope features a 5-digit, 10mm (0.4") LCD display that shows the measured Flashes Per Minute (FPM) or other selected parameters. The display is designed for clear and instant readings.

5.2 Adjusting Flash Rate (FPM)
Use the "COARSE" and "FINE" adjustment knobs to set the desired flash rate. The "COARSE" knob provides large adjustments, while the "FINE" knob allows for precise tuning. The display will show the current FPM.
- การปรับหยาบ: For significant changes in FPM.
- การปรับแต่งอย่างละเอียด: For minor, precise adjustments to FPM.
- x2 / ÷2 Buttons: Quickly double or halve the current FPM for rapid range changes.
5.3 Phase Adjustment
The phase adjustment feature allows you to shift the timing of the flash relative to the object's movement. This is useful for observing different parts of a rotating object or for achieving a specific "stillness" effect. Consult the detailed operation manual for specific phase adjustment procedures.
5.4 External Triggering
The stroboscope supports external triggering, allowing synchronization with an external signal source. This is beneficial for applications requiring precise timing with other equipment. Connect the external trigger source to the "EXT" port on the device.
5.5 Live Operation Example
When measuring the speed of a rotating object, such as a fan, adjust the FPM until the object appears stationary. The displayed FPM value will then correspond to the object's rotational speed. For defect inspection, adjust the FPM to "freeze" the object's motion at various points to identify anomalies.
