<ul><li><ul><li>1、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 (because the current is constant, only with voltage display function)</li><li>2、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 three to five seconds, the normal brightness can be achieved. The Lamp strip and bead will not be burned if the anode and cathode are reversely connected.</li><li>3、The digital display shows the real-time voltage output with an adjustable voltage, and the voltage value can be self-corrected. The digital meter adopts a green LED tube. It displays 00 to indicate a short circuit, and 300V for an open circuit. Each group of LED strips on the same LCD TV should display the same voltage.</li><li>4、Cold and heat isolation, no electric shock. The power cord and the case are designed in one, which is easy to carry.</li><li>5、You can illuminate the LCD TV screen without disassembling the screen. (The screen with the bad lamp bead is also lit up. The LCD TV is generally divided into several groups in parallel. It can be seen by the voltage which group of voltages is different, so as to determine which group of LED lamp beads are damaged). 6、Do not look directly at the lamp bead when testing because of its high brightness, avoiding hurting your eyes.</li></ul></li></ul>
