This document discusses the vernier caliper, a tool used to measure internal, external, and depth dimensions. It describes the main parts of the vernier caliper including the main scale, vernier scale, inside and outside jaws, screw clamp, and depth probe. The document explains how to properly read measurements from the vernier scale by identifying where the zero points of the main and vernier scales align. Examples are given of measuring lengths accurately to within 1/10, 1/20 and 1/50 of a millimeter. Slides provide exercises for students to practice using the vernier caliper to take measurements.
