IT03, LED Backlight strip tester. With our proprietary design, IT03 can test all types of LED strips from a smaller industrial screen and up to 70 inch TV screen. One sizes fit all! Easy to use! How to test LED Strip Turn on power switch and wait until meter on IT03 display reach at 320V (it takes about 20 second). Connect Red Probe to Anode and Black Probe to Cathode, LED strip will gradually become brighter and brighter and also voltage meter will change, too. Then brightness stops changing. This action confirms that LED string is working correctly. Repeat the same procedure to test next LED string. However, if you are not sure which pins are for anode and cathode: Connect Red probe to pin 1( or any pin), then connect Black probe to one at the time until that LED strip lights up and voltage meter also change reading, then you have found correct string. If LED strip is not light up and voltage meter will stay on 320V, then you reverse Red probe with Black probe and try it agai
