1. Use high-speed single-chip microcomputer to do voltage sampling test, and drive LED lights to display voltage (not other products on the market that use the purchased voltage meter head, which is installed separately) to realize the integration of boards and cards and reduce the defective rate (due to constant current, only voltage display function.)
2. 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 three to five seconds. 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.
3. The digital display shows real-time voltage output, with adjustable voltage inside, and 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.
4. Isolated from hot and cold, never get an electric shock. The power cord and machine box are designed in one piece, which is easy to carry when going out.
5. You can light up the LCD TV screen without dismantling the screen. (The screen with broken lamp beads lights up like a screen. Generally, LCD TVs are divided into several groups connected in parallel. You can use the voltage to see which group has different voltages, so as to determine which group of LED lamp beads is damaged)
6. During the test, please do not look directly at the lamp bead due to the bright version. so as not to hurt the eyes
