The KT4H LED TV Backlight Tester is a portable and convenient tool for testing LED backlit TVs and computers. It can handle loads up to 330V, making it compatible with most TV models. The KT4H can help you easily spot faulty LEDs, saving you time and money on repairs. These can also be used to diagnose faulty LED modules used on modern cars making them ideal for Car service technicians as well. Features: Suitable for use with most TV's, Monitors or Laptop displays that utilise LED backlighting. Real-time testing voltage and constant current drive board. Test LED strips, LED panels, single LED bead, COB lighting sources and so on. Test backlights of LED TV, displays, computers and so on. Compatible with all the LED strips (high voltage or low voltage). Manually adjustable testing voltage range (20-330V/DC) and current (20-150mA). Adjustable voltage at open circuit (without loads) and adjusting current with loads or contact probes together. No burn out when testing single LED bead with wrong polarity. (Set voltage around to 20V and the current switch to 1mA) Test voltage parameters of various of electronic components. Test LED lights on vehicles. Specifications: Suitable for use with most TV's, Monitors or Laptop displays that utilise LED backlighting. Product model: KT4H Voltage input: AC 85-265V Voltage output: DC 0-330V (Automatic + Adjustable) Voltmeter Accuracy: < (± 0.5 ± 1%Vout) V Amperage output: 0-150mA (Automatic + Adjustable) Constant Current Board Testing Current: 0-999mA Ammeter Accuracy: <(±2 ±1%Iout) mA Pinput: 50VA (MAX) Operating Temperature Range: -20℃~+40℃ Package contains: 1x KT4H Tester, 1x Mains Lead, 1x Constant Current Cable, 1x Constant Current Clip Cable, 1x Pair 20A Test Probes, User Manual Testing Methods: Default factory setting: Output Voltage 330V, Output Current 30mA. You can testing the backlight of TV with any size at this default settings. 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 In testing: Voltage = ‘0’, SHORT CIRCUIT. Voltage = ‘330V’, OPEN CIRCUIT. 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. Testing LED strips: Set the voltage to around 200V, change the current if need adjust brightness.
