Detailed explanation-1: -A vernier scale or a vernier calliper is a measuring device that is used to precisely measure linear dimensions. It is a useful tool to measure spherical and cylindrical objects. It has two main scales known as the main scale and the vernier’s scale, which are divided into small divisions.
Detailed explanation-2: -Answer: A caliper using a calibrated screw for measurement, rather than a slide, is called an external micrometer caliper gauge, a micrometer caliper or, more often, simply a micrometer. (Sometimes the term caliper, referring to any other type in this article, is held in contradistinction to micrometer.)
Detailed explanation-3: -Figure 3 shows a common use for a vernier called a vernier caliper. This caliper can measure the outside diameter of an object (outside vernier), the inside diameter of a hole (inside caliper), or the depth of a hole (depth probe).
