Vernier calipers are the trickiest calipers to read but offer a great deal of precision. Once you learn how to read a Vernier caliper, you can easily read a digital and dial caliper. Reading a Vernier caliper is a two-step process.

Least Count. The difference between one small division on main scale division and one vernier scale division is 0.1 mm. It is called the least count (LC) of the Vernier Calipers. Least count of the Vernier Calipers can also be found as given below: L.C = 0.1mm or 0.01 cm

the vernier scale that can slide along the main scale; A Vernier scale on caliper may have a least count of 0.02 mm. It is commonly used to measure accurately: outside diameters of shafts; thicknesses of various parts; diameters of holes or rings; internal dimensions of hollow jobs or articles; A micrometer may have a least count of 0.01 mm

Least count of an instrument is one of the very important tools in order to get accurate readings of instruments like vernier caliper and screw gauge used in various experiments. Least count uncertainty is one of the sources of experimental error in measurements. Least count of a vernier caliper is 0.1 mm and least count of a micrometer is 0.01 mm.

Take Exam What is Least Count ? Least Count of an instrument is the smallest change or value of a physical parameter an instrument can measure or detect. For example, the ruler shown below can not measure a dimension more than 1 mm in length. Therefore ruler L.C. is 1 mm. What is the difference between Least Count and Precision ?

This technical bulletin addresses the accuracy and calibration of digital, dial, and vernier calipers. The technical basis for this document is the American national standard (ANSI standard) entitled ASME B89.1.14-2018.

Least Count of Vernier Caliper . In simple words, the least count (or vernier reading) of a vernier caliper is the smallest distance that the caliper can measure. The least count of vernier caliper is calculated as the difference between the value of 1 division of the Main scale and 1 division of the Vernier scale. LC = 1M.S.R – 1 V.S.R

Use a vernier caliper to make measurements to the nearest 1/10 of a millimeter. Use a micrometer to make measurements nearest 10-6 meters using a micrometer. Use an electric scale to measure mass to the nearest 1/100 of a gram. Use a pendulum to measure the acceleration due to gravity. Introduction

The least count of a vernier caliper is given as (0.1) zero-point one millimeter. The least count of a Vernier caliper is also known as the Vernier constant. Each division on the main scale is equal to one millimeter. Vernier Caliper is available in two forms.

In a nutshell Use the following formula: Correct reading = Obtained reading– Zero error Correct reading = Obtained reading – Zero error where zero error zero error can be either negative (the “0” of vernier scale is left of the “0” of the main scale) or positive (the “0” of vernier scale is right of the “0” of the main scale) Explanation

Our Objective To know the use of the Vernier Calipers. To measure the diameter of a small spherical / cylindrical body. To measure the length, width and height of the given rectangular block. To measure the internal diameter and depth of a given beaker/calorimeter and hence find its volume. The Theory What is a Vernier Caliper?
