Versatile Applications: Great for testing:
LED TV backlights
LED strips (high or low voltage)
LED beads and COB lights
Constant current driver boards
Electrolytic capacitors
Electronic components like diodes, triodes, MOS tubes, and ICs
High Accuracy Testing: The voltmeter and ammeter display highly accurate measurements, ensuring precision testing every time.
⚙️ Additional Features:
Easy Setup: Plug and play functionality with intuitive self-testing modes. Begin testing in minutes with factory preset voltage (330V) and current (30mA).
Real-Time Testing: Ideal for diagnosing and calibrating:
LED backlights and driver boards
Electrolytic capacitors (measuring actual withstand voltage)
Diodes, transistors, and other electronic components
Multiple Testing Methods: The tester allows for efficient troubleshooting without dismantling screens. For LED strips, simply connect the probes and compare voltage to determine operational status.
🔧 How It Works:
Self-Testing Mode: Plug in the tester, turn on the power switch, and start testing. Voltage adjusts automatically between open circuit (330V) and short circuit (0V), with real-time current monitoring.
LED Testing: Adjust the voltage to 20V and set the current to 1mA for single LED bead tests. The tester will display voltage based on correct polarity, while incorrect polarity shows an open circuit voltage.
Capacitor Testing: Use the voltage around 20V for diodes, transistors, and electrolytic capacitors to assess breakdown voltage or actual withstand voltage.
