In the video, a person is seen holding a blue multimeter in their right hand and a red and black wire in their left hand. The person is standing in front of a beige machine. The person inserts the red wire into the red port on the machine and the black wire into the black port. They then turn the dial on the multimeter to the right and the screen lights up. The person then turns the dial to the left and the screen goes out. They repeat this process several times, turning the dial to the right and the screen lights up, and turning the dial to the left and the screen goes out.
