Vernier Caliper Definition: A vernier scale (Vernier Caliper) is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation ; thereby increasing resolution and reducing measurement uncertainty by using Vernier acuity to reduce human estimation error. Components: Internal jaws, External jaws, Main arm, Sliding arm, Depth measuring probe, Locking Screw. Working principal: The vernier scale works on the principle of using alignment of line segments displaced by a small amount to make fine measurements. Human eye can easily detect this alignment of lines which is the main fact that drives a vernier . A vernier scale has a main scale and a vernier scale . Applications: Uses of Vernier Calipers . We know the core uses of Vernier Calipers is for measuring the distance between two opposite side...
