LED Backlight Tester for TV - Professional Constant Current Plate Universal Tester Voltage Tester LED Lamp Tester with Meter Pen & Storage Bag for Computer All LED Lights Repairs(#1)

CHECK THE FAULT - Our LED TV backlight tester is a powerful tool for diagnosing and testing LED TV backlight issues. It allows you to easily determine the fault problem in LCD TVs by testing the LED backlight and separating the TV constant current board. It is capable of testing various components such as diodes, voltage regulators, transistors, capacitors, varistors, and TVS transient diodes, with a voltage resistance or breakdown voltage of up to 330V.

VOLTAGE & CURRENT TEST - With its manual stepless presetting of the open circuit voltage (20?330VDC), our LED TV backlight tester intelligently adapts to the LED light source voltage during testing, eliminating the need for adjustments. It can also be manually and steplessly preset with the maximum short circuit limit current (20?150mA), and the current is automatically and intelligently adjusted during the test.

EFFECTIVE TEST - When the output voltage is set to 20 or below, our LED TV backlight tester can accurately test voltage parameters of power supply legs for various ICs using a 1mA grade current. This allows for a simple determination of whether the IC is functioning properly or not.

EASY TO USE - Our LED lamp tester is designed for user-friendly operation. It features a special additional lmA accuracy wide voltage (0?330V) constant current source output, providing you with the flexibility to develop clever applications on your own. Explore and utilize this tester easily and efficiently.

LONG-LASTING - Testing the backlight of LED display the voltage, It can be tested in a long time, and will not damage the lamp beads. Designed for durability, this tester can be used for long periods without losing its effectiveness. It is built to withstand frequent use, making it a trusted tool that will last.
