[0002] LED digital tubes are used to display numbers and other information, and are widely used in practice. In the production process of digital tubes, it is necessary to test the power supply of the digital tubes so that qualified digital tubes can enter the market. There are multiple pins arranged on the digital tube, and the pins correspond to different pen segments on the digital tube. People usually use the positive and negative probes of a multimeter to contact the pins one by one. If the pin being tested is not damaged, the pen segment of the digital tube will light up. If the pin being tested is damaged, the pen segment of the digital tube corresponding to the tested pin will not light up. In this way, the digital tube can be tested.
