Product Name: 0-320V LED TV Backlight Tester for LED Strips Model NO.: XIAOYUN Customized: Non-Customized Power Source: 0-320V Warranty: Without Warranty Environment: Room Temperature Usage: Electric Component Tester Display: Digital Function: Tester Input Voltage: 85-265 V Output Current: 0-35mA Transport Package: Carton Origin: Guangzhou Product Description Product Decription:Input voltage: 85-265 V international generalOutput voltage: 0-320 VAdditional application:The capacitance voltageThe voltage regulatorworth 3 lamp drive voltage test!Examination skills:- 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.Single LED light bar backlight checking:1. Plug in power, it would be cost about 3 to 5 seconds to start2. The soft start mode make the backlight getting brighter gradually3. If you can't make sure which is"+"and "-", then not test for a long time4. Don't touch the output terminal of probes for a long time 5. Retardancy materials: Double Isolate design makes tester safety with high strength and flame6.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 mutilatedNotice:Please, if you are used to the LED lamps finished, unplug the power supply before!Because it is likely to form a loop, which in Abnormal test!Detailed Pictures:Packaging & Shipping:PackagingNormal packaging.Export carton.Custom packing.ShippingAll orders are will be shipped within 5-15days after customers confirmed payment.Our services:Your inquiry related to our products or prices will be replied ASAP.Well-trained and experienced staffs to answer all your enquires in fluent English.Any your customized lightings we can help you to design and put into product
