• Suitable for single LED beads, LED stirng, LED panel and Integrated optical LED
• Support testing the capacitance voltage and the diode voltage
• No need to disassemble panel to test the LED backlights
• Safe Protection: Double Isolated 
• Brun prtection: Voltage and Current Intelligent Adjustment 
• Safety design : Slow boost , soft start. Increase the current steadily. 

Characteristics

• Plug in power, it would be cost about 3 to 5 seconds to start
• The soft start mode make the backlight getting brighter gradually
• If you can't make sure which is“+”and “-”, then not test for a long time
• Don’t touch the output terminal of probes for a long time 
• Retardancy materials: Double Isolate design makes tester safety with high strength and flame
• If the tested LED TV's backlight voltage is 000, that means short circuit,if the voltage is 300,that means open circuit. Every light's voltage of the TV should be same,if it is not, then the LED light bar is mutilated
