2. Безбедносне информације
Please read and understand all safety instructions before operating the device. Failure to follow these instructions may result in electric shock, fire, or damage to the product or other property.
- Double Isolation Design: The tester features a double isolated design for enhanced safety.
- Заштита од опекотина: Интеллигент волtage and current adjustment prevents burning of LED beads.
- Slow Boost, Soft Start: The safety design incorporates a slow boost and soft start mechanism, gradually increasing current to prevent sudden surges.
- Avoid Prolonged Contact: Do not touch the output terminals of the probes for extended periods during operation.
- Поларитет: If you are unsure about the positive and negative polarity of the LED, avoid testing for a prolonged duration.
- Искључите када се не користи: Always turn off the power when the tester is not in use.
3. Подешавање
Follow these steps to prepare your TKDMR LED Lamp Bead TV Backlight Tester for use:
- Connect the provided US Power Plug to the tester's power input port.
- Plug the power plug into a standard AC 110-265V electrical outlet.
- Connect the test probes to the designated output terminals on the tester. Ensure a secure connection.
- Turn on the power switch located on the side of the tester. The device will take approximately 3 to 5 seconds to initiate.
- Observe the digital display. After the initial startup, the voltmeter will display the normal 300V value.
4. Упутство за употребу
The TKDMR LED Lamp Bead TV Backlight Tester is designed for ease of use with its intelligent voltage and current adjustment.
Општа операција:
- After plugging in and powering on the device, allow 3 to 5 seconds for it to start. The soft start mode will gradually increase the backlight brightness.
- Use the test probes to contact the LED components you wish to test. The tester will automatically adjust the output voltage (0-300V) and current (30mA) to safely illuminate the LEDs.
- Observe the digital display for the output voltage reading. This indicates the voltage required by the LED or LED strip being tested.
- If testing an LED strip, the tester can identify defective LEDs quickly without requiring panel disassembly.

5. Одржавање
To ensure the longevity and optimal performance of your TKDMR LED Lamp Bead TV Backlight Tester, follow these simple maintenance guidelines:
- Чишћење: Обришите уређај меком, сувом крпом. Не користите абразивна средства за чишћење или раствараче.
- Складиштење: Тестер чувајте на хладном и сувом месту, даље од директне сунчеве светлости и екстремних температура.
- Брига о сонди: Inspect the test probes regularly for any signs of wear or damage. Replace them if necessary to ensure accurate and safe operation.
- Кабл за напајање: Ensure the power cord is not kinked or damaged.
КСНУМКС. Решавање проблема
This section addresses common issues you might encounter with your LED Backlight Tester.
- Тестер се не укључује:
- Ensure the power plug is securely connected to both the tester and a working electrical outlet.
- Проверите да ли је прекидач за напајање у положају „УКЉУЧЕНО“.
- LEDs do not light up or flicker:
- Check the connection of the test probes to the LED component. Ensure good contact.
- Confirm the polarity of the LED if testing individual beads. While the tester has burn protection, incorrect prolonged contact is not recommended.
- The LED component itself might be faulty. The tester is designed to help identify such components.
- Нетачна волtage reading:
- Ensure the probes are making firm and clean contact with the test points.
- Allow the tester to fully initialize (3-5 seconds) after power-on before taking readings.
