SFD290 LED LCD TV Backlight Tester Meter Repair Tool Lamp Beads 85-245V 0-300V
Feature:1. Use high‑speed single‑chip microcomputer for voltage sampling test, and drive LED lights to display voltage to achieve board‑card integration and reduce defect rate.
2. 0‑300V adaptive voltage, suitable for most series and parallel lamp beads testing. During the test, the gradual start method is adopted, and the voltage automatically adapts to the gradual increase of the current, and the lamp beads will never be burnt, and the normal brightness can be reached after three to five seconds. The positive and negative poles of the lamp bar and the lamp bead are connected reversely, and the lamp bar does not burn and lamp beads.
3. Digital display real‑time voltage output, with adjustable voltage inside, voltage value can be self‑calibrated. The digital meter uses a green light‑emitting tube, the display of 00 means short circuit, and the display of 300V means open circuit. The display voltage of each group of LED strips of the same LCD TV should be the same
4. Isolate hot and cold, never get an electric shock. Integrated design of power cord and box, easy to carry when going out.
5. Can light up the LCD TV screen without disassembling the screen. (The screens with broken lamp beads will light up the same. LCD TVs are generally divided into several groups in parallel. You can see which group of voltages are different from the voltage, so as to judge which group of LED lamp beads are damaged)
