As is well known by that the Vernier caliper is found having two scales the main scale and the Vernier scale, both of this make an arrangement to measure very small lengths like that of 0.1mm and so on. The Principle of Vernier CaliperДЄ scale cannot measure objects which are smaller than 1mm whereas a Vernier caliper can measure objects up to 1mm. There is a metal strip observed which is attached at the back of the Vernier caliper and is helpful in measuring the internal depth of a cylinder. The external jaw which is also known as the lower jaws is generally used to measure the diameter of a sphere or a cylinder whereas the internal jaws or the upper jaws are the ones which are generally used to measure the internal diameter of a hollow cylinder. These are the jaws which are used together to hold the object tightly during the measurement of its length which is impossible using a meter scale. There are two jaws which are found on the Vernier caliper one is the upper jaw and other is the lower jaw.

There is one more, small rectangular metal strip which is graduated along with a special relation to a main scale which is termed as the Vernier scale and slides over this long metal strip when it has a jaw that is similar to that of the main scale. Vernier Scale : ( Parts of Vernier Caliper ) This is what allows improvements in the popularly used measuring techniques along with the direct measurements using the line graduated method.

markings are divided into 20 parts so that a small division can be equal to 0.05 cm. The main scale can be seen on the solid L shape frames, on which the cm. One is observed to be a long rectangular metal strip which has a fixed jaw on one end and is graduated in inches at its upper end, few centimeters at its lower end which is known to be the main scale. Vernier caliper mostly consists of two steel rules which can slide along with each other. Main Scale : ( Parts of Vernier Caliper ) So, the main elements of the Vernier caliper are as follow: So here comes a need to properly know the elements of Vernier caliper which are mentioned below. Parts of Vernier CaliperДЄs a Vernier caliper is high in demand at places where there is requirement of a highly accurate measurement. The principle on which a Vernier caliper works is that whenever there are two scales or divisions which are slightly different in size, then the difference within them is used so that the accuracy of the measurement can be increased.
