The Vernier caliper is used for measuring the accurate length of a given object. They are used to provide accurate results. They even produce zero error in measurement.
The Vernier Caliper has two scales such as Main scale and Vernier scale tends to coincide while taking measurement, then said to have zero error accuracy.
It happens when the jaws of Vernier caliper brought together and the zero mark on Vernier caliper scale comes in proper alignment with the zero of main scale.
