LED Lamp Bead TV Backlight Tester with Power Switch/Probe Pens/Power Cable, 0-300V Adaptive Voltage LED Strip Lamp Beads Light Source Testing Tool for All LED Lights Repair (Black)

Digital Display LED Lamp Beads TesterTV Computer Backlight Tester Light Beads Strips Backlights Repair Testing Tool with Probe Pens for All LED Lights Repair Description: - Used to test LED light strips, light strip LED panels, backlights, etc, without disassembling the screen, and can determine which group of LED lamp beads is damaged. - 0-300V adaptive voltage, suitable for testing most series and parallel lamp beads. During the test, the gradual start-up method is adopted, the voltage is automatically adapted, the current is gradually increased, and the lamp beads will never be burned, and the normal brightness can be reached after 3-5s. - The positive and negative poles of the light bar and lamp bead are reversed, and the light bar and lamp bead will not be burned. - High-speed single-chip microcomputer is used for voltage sampling test, and the LED lamp is driven to display the voltage, so as to realize the integration of boards and cards and reduce the defect rate (due to constant current, only voltage display function is performed.) - Digital display real-time voltage output, with adjustable voltage inside, the voltage value can be corrected by itself. The digital meter uses a green light-emitting tube, and the display of 00 means a short circuit, and the display of 300V means an open circuit. Each group of LED light bars of the same LCD TV should display the same voltage. - The power cord is integrated with the shell, easy to carry when going out, insulated, and will not get an electric shock.
