Vernier Caliper Diagram, Construction and working principle

Vernier Caliper is a precise measuring instrument, Comparatively low accuracy than the other precision measuring instruments. The different types of Vernier callipers are available to measure internal, external measurements, depth of holes. Vernier caliper consists of two scales. One is fixed and the other is movable. The fixed scale is called the main scale. It is a calibrated L-shape frame and carries a fixed jaw. the movable scale, called Vernier scale. Which is slides over the main scale and carries movable jaw. these movable and fixed jaws having to measure tips for internal and external measurements. Before measuring the instrument it should be checked for zero error. The zero lines on the vernier scale should coincide with zero on the main scale. The formula to calculate the total reading is given below. The total reading = The main scale reading + (the number of the division at which it exactly coincides with any division on the main scale X least count of vernier calliper).
