Use STM8 high-speed single-chip microcomputer to do voltage sampling test, and drive LED light to display voltage, realize board integration, reduce the defect rate (because the current is constant, there is only voltage display function).
0-300V adaptive voltage, suitable for most series and parallel lamp bead test. During the test, the progressive start mode is adopted, the voltage is automatically adapted, and the current is gradually increased, so the lamp bead will never be burned, and the normal brightness can be achieved after three to five seconds. Even if the light bar and the lamp bead are reversed, the light bar and the lamp bead will not be burned.
The digital display shows the real-time voltage output with an adjustable voltage inside, and the voltage value can be self-corrected. The digital meter uses a green light-emitting tube. When it is displayed as 00, it indicates a short circuit, and when it is 300V, it indicates an open circuit. Each group of LED strips on the same LCD TV should display the same voltage.
Cold and heat isolation, no electric shock. The power cord and the case are designed in one piece, which is easy to carry out.
The brightness is higher than the market's similar highlight version of 30%! Can test any size LED backlight and lamp bead.
