What is vernier caliper with diagram?
Vernier scale is a visual aid, That allows the user to read measurements more precisely than any other instrument. Vernier scale indicates where the measurement lies in between two of the graduations on the main scale. See the following GIF to understanding how the vernier scale is moving over the main scale.
What are Vernier calipers used for?
We know the core uses of Vernier Calipers is for measuring the distance between two opposite side of a surface. We can measure the internal and external dimensions and even the height of an object with accuracy. It can measure up to one-hundredth of a millimeter.
What is Vernier caliper PDF?
1. A Vernier Calliper has two scales–one main scale and a Vernier scale, which slides along the main scale. The main scale and Vernier scale are divided into small divisions though of different magnitudes. The main scale is graduated in cm and mm. It has two fixed jaws, A and C, projected at right angles to the scale.
What are the main parts of Vernier caliper?
Parts of a vernier caliper:
- Outside jaws: used to measure external diameter or width of an object (Blue)
- Inside jaws: used to measure internal diameter of an object.
- Depth probe: used to measure depths of an object or a hole ( not shown in this model)
- Main scale: gives measurements in mm.
What is scale in engineering drawing?
Definition. A scale is defined as the ratio of the linear dimensions of the object as represented in a drawing to the actual dimensions of the same.
What is the 3 basic uses of a vernier caliper?
(a) Measuring the internal diameter of a tube or a cylinder. (b) Measuring the length of an object. (c) Measuring the depth of a beaker or a bottle.
How do you read a vernier caliper?
Follow these steps to read the vernier scale:
- Read the main scale. Look for the last whole increment visible before the 0 (zero) mark.
- Read the secondary scale (Vernier) measurement. This is the division tick mark that lines up best with a mark on the main scale.
- Add the two measurements together.
What is the range of Vernier caliper?
Vernier calipers commonly used in industry provide a precision to 0.01 mm (10 micrometres), or one thousandth of an inch. They are available in sizes that can measure up to 1828 mm (72 in).

What are the types of vernier?
Type A, B, and C. Vernier calipers are classified based on an international standard IS 3651-1974, according to this standard three types of vernier calipers have been specified to meet external and internal measurement requirements of up to 2000mm with the accuracy of 0.02, 0.05, and 0.1 mm.
What is RF in drawing?
Explanation: Representative factor is the ratio of the length represented in drawing to the actual length. Here given actual length is 1 cm and length of drawing is 30 cm. R.F. = 30 cm/1 cm = 30.
