B07GPGVN99 Availability: Currently unavailable Score: 6.579 Category: Tools Rating: 4.7 Votes: 126 Find similar products TKDMR Multipurpose Tester for LED TV Backlight and Constant Current Driver Board - Used in All LED Lights Repair Output 0-330V. Product model: TD3H Vin: AC 85-265V Vout: DC 0-330V (Automatic + Adjustable) Voltmeter Accuracy: <(± 0.5 ± 1%Vout) V Iout: 0-150mA (Automatic + Adjustable) Constant Current Board Testing Current: 0-999mA Ammeter Accuracy: <(±2 ±1%Iout) mA Pinput: 50VA (MAX) Temperature: -20℃~+40℃TESTING METHO Default factory setting: Output Voltage 330V, Output Current 50mA. You can testing the backlight of TV with any size at this default settings. 1. Self-testing: Plug in, turn the power 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, change the current if need adjust brightness. Test method of Constant Current Driver Board Testing situation: the LED strip of backlight is on with the tester, but it does not work with the constant current board; A. Cut off the power of TV, unplug the interface sockets of the constant current plate and light bar; B. Connect the constant current board with the tester using the cables in the kits on right polarity. C. Insert the Red and Black pens of the tester into the anode and cathode of the interface of the LED light bar D. Turn the power of TV on. E. Testing voltage >30V, Current >30mA and keep stable, and the LED strip working normal.
