In the video, a person is holding a digital caliper in their left hand and a metal object in their right hand. The caliper has a digital screen that displays the measurement of the object. The person is using the caliper to measure the diameter of the metal object, which appears to be a bolt or nut. The digital screen of the caliper is visible, and the measurement is shown in millimeters. The person adjusts the caliper to get a more accurate measurement, and the screen displays the new measurement. The background is blurred, but it seems to be a workshop or garage setting.
