<ul><li>Real-time testing voltage and current of current drive board.1. Testing LED strips, LED panels, single LED bead, COB lighting sources and so on.2. Testing backlight of LED TV, displays, computers and so on. 3. Compatible with all the LED strips (high voltage or low voltage).4. No burn out when testing single LED bead with wrong polarity. (Set voltage around to 20V and the current switch to 1mA)5. Testing voltage parameter of various of electronic components. 6. Testing LED light on vehicle.Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so onProduct ParametersProduct model: KT4HVin: AC 85-265VVout: DC 0-330V (Automatic + Adjustable)Voltmeter Accuracy: Less than ( 0.5 1%Vout) VIout: 0-150mA (Automatic + Adjustable) Current Board Testing Current: 0-999mAAmmeter Accuracy: Less than (2 1%Iout) mAPinput: 50VA (MAX)Temperature: -20~+40Testing MethodsDefault factory setting: Output Voltage 330V, Output Current 30mA. You can testing the backlight of TV with any size at this default settings.1. Self-testing: Plug in, turn the switch on. The voltage is around 330V, current is 0; Contact the probes together, voltage changes to 0 and current changes to around 50mA, then testing can be started. 2. In testing: Voltage = '0', SHORT CIRCUIT.Voltage = '330V', OPEN CIRCUIT.3. Testing single LED bead (Set voltage around to 20V and the current switch to 1mA):A. With right polarity: the voltage shows on the tester of a normal LED bead is about 80% of the rated voltage, for example, the operating voltage of the LED bead is 2.4V if its rated voltage is 3V; B. With wrong polarity: Voltage display the open circuit voltage. 4. Testing LED strips: Set the voltage to around 200V, the current if need adjust brightness.size:about 108x65x33mmMaterial:plasticcolour:WhitePackage Contents:1 x KT4H 0-330V LED TV Backlight Tester setOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
