However, the output must be connected to a load with a matching voltage. Therefore, connect the constant current board's output to the constant current input interface of the KT4H tester. Connect the tester's output to the positive and negative terminals of the LED strip via multimeter probes. Then, power on both the tester and the constant current board. The tester will display the current and voltage of the constant current board. If the current is stable, the constant current board is working properly.\u003c\/p\u003e\n\u003cp class=\"description\"\u003eQ: Is this multi-functional tester accurate for testing LED strips?\u003c\/p\u003e\n\u003cp class=\"description\"\u003eA: Yes, it is accurate. It can test and diagnose both single and multiple backlight groups without disassembling the screen; it can also safely handle both high-voltage and low-voltage LED strips. In addition to the basic functions of a tester, this multi-functional tester also includes constant current board testing and stepless current and voltage adjustment.\u003c\/p\u003e\n\u003cp class=\"description\"\u003eQ: How do I test the quality of a TV with a single LED strip?\u003c\/p\u003e\n\u003cp class=\"description\"\u003eA: This KT4H tester can perfectly solve the backlight testing problem for TVs with a single LED strip. The problem is determined by testing the constant current board. If the constant current board is normal, then the LED strip is definitely faulty.\u003c\/p\u003e\n\u003cp class=\"description\"\u003eQ: My TV backlight flickers and then goes out. Can this tester determine if the problem is with the constant current board or the LED strip?\u003c\/p\u003e\n\u003cp class=\"description\"\u003eA: Testing only the LED strip cannot confirm whether the problem lies with it. Testing the constant current board simultaneously will provide a more accurate diagnosis.\u003c\/p\u003e\n\u003cp class=\"description\"\u003eQ: Will connecting the LED strip backwards burn out the LEDs?\u003c\/p\u003e\n\u003cp class=\"description\"\u003eA: No. The main purpose is to check the current value of the LED strip.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MULBRANTEX","offers":[{"title":"Default Title","offer_id":44257307492435,"sku":"KT4H","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/8947\/files\/kt4h-MI.jpg?v=1774516288"}],"url":"https:\/\/mulbrantex.com\/collections\/mulbrantex-professional-tester.oembed","provider":"MULBRANTEX","version":"1.0","type":"link"}
