What is the Vernier scale?

The vernier scale adds an extra degree of accuracy to measurements. On the vernier scale, the smallest increment on the main scale is further divided. The metric vernier scale is divided into 50 equal parts. The measuring range of the vernier scale is usually 1 mm, with each increment representing 0.02 mm. On an imperial caliper with a main scale of 6 inches, the vernier scale is 0.6 inches long and is divided into 25 parts. Each increment has a length of 0.001 inch.

What is a Vernier caliper?

The Vernier caliper is a measuring instrument. The instrument consists of various parts and it is a good idea to be acquainted with these parts and their possible replacements so that the measuring device can be used to perfection. Vernier caliper jaws are used to take the inside measurements of an object, such as the diameter of a hole or a slot.

How is a caliper adjusted?

The caliper is adjusted by moving the instrument’s jaws back and forth. The measurement is read from the left of the Vernier scale. The scale is marked either in inches or in centimeters. The sliding jaw and the depth probe are linked to the Vernier scale, which means that they will only move along the Vernier scale.

Is a Vernier caliper dial mode?

In almost all industries people were using the vernier caliper, not of dial mode and thereby there is a little chance (in terms of microns) that they will get an error. The basic difference between the standard vernier and the Dial Vernier is as follows.

What is the least count of Vernier callipers?

The least count of vernier callipers is also known as the vernier constant. It is defined as the difference between one main scale division and one vernier scale division. It is mathematically given as: When there are n divisions on the vernier scale which coincides with (n-1) division on the main scale, then the least count of vernier calliper is:

How many divisions are there on the Vernier scale?

The number of divisions on the vernier scale, in general, are 10 divisions. Therefore, the number of divisions on the main scale is given as n-1 = 10 – 1 = 9 which is equal to 9 mm. Therefore, we can say that each division on the vernier scale is equal to 1/10 mm.

What does it mean when the main scale reading and the vernier scale reading are at zero?

When the main scale reading and the vernier scale reading are at zero, it means there is no zero error. Now, place a ball between the two jaws of the vernier scale. Look at the 0 mark on the vernier scale lining with the main scale. That gives the main scale reading.

What is the function of the Vernier scale?

The main function of the vernier scale is to provide accuracy to the main scale reading by dividing the reading into smaller increments.

Vernier Calliper Diagram. French mathematician Pierre Vernier invented the vernier scale in 1631. The main use of the vernier calliper over the main scale is to get an accurate and precise measurement.

How to measure depth of jars?

The depths of the jars can be measured using the depth rod. It is a thin rod located at the end of the main scale. Using a depth rod for measuring is simple. The edge of the main scale is placed on the top surface of the object, then the jaws are slowly opened. The opening of the jaws results in the extension of the depth rod. Until the depth rod reaches the bottom of the object, the jaws need to be opened.
