You can testing the backlight of TV with any size\nat this default settings. 1. Self-testing: Plug in, turn the power switch on.\nThe voltage is around 330V, current is 0; Contact the probes together, voltage\nchanges to 0 and current changes to around 50mA, then testing can be started.\n2. In testing: Voltage = ‘0’, SHORT CIRCUIT. Voltage = ‘330V’, OPEN CIRCUIT.\n3. Testing single LED bead (Set voltage around to 20V and the current switch\nto 1mA): A. With right polarity: the voltage shows on the tester of a normal\nLED bead is about 80% of the rated voltage, for example, the operating voltage\nof the LED bead is 2.4V if its rated voltage is 3V; B. With wrong polarity:\nVoltage display the open circuit voltage. 4. Testing LED strips: Set the\nvoltage to around 200V, change the current if need adjust brightness. Test\nmethod of Constant Current Driver Board Testing situation: the LED strip of\nbacklight is on with the tester, but it does not work with the constant\ncurrent board; A. Cut off the power of TV, unplug the interface sockets of the\nconstant current plate and light bar; B. Connect the constant current board\nwith the tester using the cables in the kits on right polarity. C. Insert the\nRed and Black pens of the tester into the anode and cathode of the interface\nof the LED light bar D. Turn the power of TV on. E. Testing voltage \u0026gt;30V,\nCurrent \u0026gt;30mA and keep stable, and the LED strip working normal, then the\nConstant current board is normal.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eReal-time testing voltage and current of constant current drive board.\u003c\/li\u003e\n         \u003cli\u003eTesting LED strips, LED panels, single LED bead, COB lighting sources, backlight of LED TV, displays, computers and so on.\u003c\/li\u003e\n         \u003cli\u003eTesting voltage parameter of various of electronic components;Testing LED light on vehicle.\u003c\/li\u003e\n         \u003cli\u003eNo burn out when testing single LED bead with wrong polarity.
