LED Light and TV Backlight Tester, 85‑265V Circuit Board Trace Repair Super LED Tester LED Lights Repair Tester for TV Manufacturing Repair

• Adjustable Circuit: Digital display real time voltage output, with adjustable voltage, voltage value can be corrected by itself. The digital meter uses green luminescence tube, the display of 00 is short circuit, the display of 300V is open circuit.
• Without Removing Screen: You can not remove the screen, light up the LCD TV screen, there is a bad lamp bead screen lit, LCD TV is generally divided into several groups of parallel, can be seen through the voltage which group of voltage is different, so as to judge which group of LED lamp bead damage.
• 0‑300V Adaptive Voltage: Suitable for most series and parallel bead tests. Test use gradual starting mode, voltage automatically adapt, current gradually increase, never burn lamp beads, reach the normal brightness after three to five seconds.
• Insulation and Portable: Hot and cold isolation, never electric shock. Power cord and box integrated design, easy to carry out.
• Excellent Single Chip Mcrocomputer: Using high speed single chip microcomputer to do voltage sampling test, and drive LED lamp display voltage (not other products on the market with the purchase of voltmeter head, separate installation), to achieve board integration, reduce the defective rate(due to constant current, only do voltage display function).

Specification: Item Type: Super LED Tester Material: ABS How to Use: When testing, do not look directly at the bead due to the highlighted version. So as not to hurt the eyes. Package List: 1 x Tester 1 x Red Test Pen 1 x Black Test Pen 1 x User Manual Note: 1. When you are unsure of the positive and negative electrodes, use 19V voltage to detect the positive and negative electrodes. Do not use 300V voltage to detect the positive and negative electrodes. The 300V voltage may damage the device. 2. Short connect the marker plus or minus three seconds to switch between high and low voltage.
