Product Information:
A Vernier scale is a visual aid to take an accurate measurement reading between two graduation markings on a linear
scale by using mechanical interpolation; thereby increasing resolution and reducing measurement uncertainty by
using Vernier acuity to reduce human estimation error. The difference between the value of one main scale division
and the value of one Vernier scale division is known as least count of the Vernier. It is also known as Vernier
constant. Let the measure of the smallest main scale reading, that is the distance between two consecutive
graduations (also called its pitch) be S and the distance between two consecutive Vernier scale graduations be V such
that the length of (n − 1) main scale divisions is equal to n Vernier scale divisions. Then,
the length of (n − 1) main scale divisions = the length of n Vernier scale division, or
