What are the Errors of Vernier Calipers?

In order to take measurements for the linear dimensions while performing various important experiments in the Physics Laboratory, the Vernier Calipers equipment is very important. However, many students often don’t know how to use them or generally get confused while using them. Therefore, to help these students, we have put together a detailed description of the vernier calipers and how they are going to use them to round objects.

The vernier caliper is made up of two scales. The first is fixed, whereas the second is mobile. The fixed scale is referred to as the primary scale. It has a calibrated L-shaped frame with a fixed jaw. The Vernier scale is moveable. As shown in the vernier scale diagram the scale slips over the main scale and has a moveable jaw. Internal and exterior measurements are taken using these moveable and fixed jaws.

Errors of Vernier Calipers

There are different types of errors in Vernier Calipers, which we are going to discuss in detail below.

No Zero Error

As you can guess from the title itself, in this type of error, the two jaws of the vernier calipers are brought together. In this case, the main scale coincides with zero on the vernier scale.

Positive Zero Error

If the zero of the vernier calipers is ahead of the main scale, or if the zero of the vernier calipers is towards the right side of the main scale. This is known as a positive zero error.

Negative Zero Error

If the vernier scale is towards the left side of the main scale, for instance, the location of zero on the vernier scale is towards the backside, then it is referred to as a negative zero error.

We have provided a detailed description of the Vernier Calipers, the vernier caliper diagram, their applications, various parts, different types of errors in vernier scales, and many more.
