This is the detailed explanation of Vernier Caliper along with its Formula, Construction, Experiment. 300mm. so, Least count = ( smallest division on main scale) / ( total no. He also likes to write articles related to the mechanical engineering field and tries to motivate other mechanical engineering students by his innovative project ideas, design, models and videos. The depth rod is used for measuring the depth of holes. February 10, 2017 […] Reading a vernier caliper is tricky. Vernier calipers are not a rugged instrument, hence they should not be treated or used as wrench or hammer. Inside measurements. The main scale runs along the beam of the caliper. The detailed explanation of Vernier Caliper is as follows. Sachin is a B-TECH graduate in Mechanical Engineering from a reputed Engineering college. How to Read a Metric Vernier Caliper - WeldNotes.com. Vernier caliper depth rod. Least count is nothing but the smallest possible value that can be measured using instruments. If What you looking for is not here, you may send a request to modify articles, Notes, and Content modification, Feedback, Suggestions here (Team will reply as early as Possible ): Contact Form or Using Whatsapp, © 2020 Copyright Learn Mechanical Engineering, vernier caliper how to use, parts, least count, Least count is nothing but the smallest possible value that can be measured using instruments. i.e., Vernier scale reading = … The VERNIER is a small movable graduated scale for obtaining fractional parts of subdivisions on a fixed main scale of any measuring instrument. Standard Vernier: Manual Reading (You need to check manually). One is the Main Scale and the other is the Vernier Scale. The improper conditions of the jaws of the caliper, like natural wear and warping, so the caliper jaws must be tested frequently by setting the 0.0 point of the main and vernier scales. , with each increment representing 0.02 mm and has 50 divisions on vernier,!
