LEAST COUNT OF VERNIER CALLIPER PDF

The least count of an instrument is the smallest measurement that can be taken accurately Vernier callipers, an instrument for making very accurate linear. 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.

Measured values are good only up to this value. Number of divisions on Vernier scale: If the zero of the Vernier scale is to the right of the zero of the main scale then the error is positive.

This blog explains the procedure of calculating the least count of the metric vernier caliper. Use a magnifying glass if necessary. The least count of an instrument is inversely proportional to the precision of the instrument. LC of vernier caliper is the difference between one smallest reading of main scale and one smallest reading of vernier scale which is 0.

Use of Vernier Calipers

We will vednier this example step by step. To get the least count of the main scale, count the number of divisions on the main scale in one cm of it. Any measurement made by the instrument vernirr be considered repeatable to no less than the resolution of the least count. Knowledge Bank Home Hand tools How to calculate the least count of the metric vernier caliper? This Blog is Taggged: By repeating the observations and taking the arithmetic mean of the result, the mean value would be very close to the true value of the measured quantity.

Least count – Wikipedia

The main scale is graduated is centimeter while Vernier scale slides along the main scale and fo graduated in division less than the millimeter. It is used by the lathe mechanic for making metallic cylinders of different sizes.

The least count error is the error associated with the resolution of the instrument.
