LED Backlight Tester for LCD TV, LED Lamp Bead and Backlight Tester, English Version High Brightness LED Backlight Bead Tester TV Repair Tool(US)

Adopt high-speed single-chip microcomputer to do voltage sampling test, and drive LED light display voltage (not the voltage meter used by other products on the market, separate installation) to achieve board integration, reducing the defect rate (becaus 0-300V self-adaptive voltage, suitable for most series and parallel lamp bead test.

Progressive start mode is adopted during the test.

The voltage is automatically adapted while the current is gradually increased, and the lamp bead is never burned.

After The digital display shows the real-time voltage output with an adjustable voltage, and the voltage value can be self-corrected.
