VERNIER CALIPER LEAST COUNT PDF

The least count of an instrument is the smallest measurement that can be taken accurately Vernier callipers are widely used in scientific laboratories and in. 6 Jul Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions of vernier scale. Least Count plays an important role in measurement devices like Vernier Caliper. This blog explains the procedure of calculating the least count of the metric.

Least count

A stopwatch used to time a race might resolve down to a hundredth of a second, its least count. The main scale is graduated is centimeter while Vernier scale slides along the main scale and is graduated in division less than the millimeter.

The least count error is the coint associated with the resolution of the instrument. Since the zero error is negative, the zero correction will be positive. Scientific notation and significant figures Scientific notation and significant figures are two important terms in physics.

Knowledge Bank Home Hand tools How to calculate the least count of the metric vernier caliper? If the zero of the Vernier scale is to the right of the zero of the main scale then the error is positive. By using this site, you agree to the Terms of Use and Privacy Policy.

The thickness or external diameter of an object. When the jaws of Vernier calipers counf brought into contact, the zero of the Vernier must coincide with the zero of the main scale.

LC of vernier caliper is the difference between one smallest reading of main scale and one smallest reading of vernier scale which is 0.

Vernier caliper is an instrument used to measure the length, diameter, radius etc. Least count error [ edit ] The smallest value that can be measured by the measuring instrument is called its least count.
