The Phewnyzo KT4H Multi-Function Tester is designed for testing TV backlights, constant current boards and a wide range of LED lighting components during repair and maintenance work. It can test constant current driver boards, perform real-time voltage and current detection for various electronic components and support TV screen testing without disassembly. This screen-free testing approach helps you check the backlight or board while the screen remains assembled.Manual voltage and current controls let you customize the testing range for the task at hand. The test voltage can be adjusted from 20 to 330V DC, while the test current can be adjusted from 20 to 150mA. Stepless adjustment is also provided for testing individual LED beads. For single LED bead testing when the polarity is incorrect, the source recommends setting the voltage around 20V and the current switch to 1mA. Follow this setup for the stated no-burnout testing condition and use the controls carefully for the component being checked.This multi-function tester is intended for LED light repair applications that include LED strips, LED panels, single LED beads, COB lighting sources, TV backlights, displays, computers and vehicle LED testing. It is also described for maintenance and repair of DIY home appliances, making it suitable for different electronic troubleshooting tasks that require adjustable voltage and current testing.The box contains one KT4H multi-tester, one test probe, one power cord, one socket cable, one connection clip, one bag and one user manual. The tester has product dimensions of 4.51 x 2.59 x 1.38 inches and a product weight of 14.4 ounces. These are the tester measurements and weight, not the shipping package measurements. The package measures 10.2 x 6.3 x 2 inches and weighs 1.01 pounds. Use the included probe, socket cable and connection clip as specified by the user manual for the applicable testing task.
