Hi friends in this channel you are going to learn about fundamental of electrician. electrician theory, electrician practical knowledge, electrical fundamental & knowledge.
It is a large scale that runs along the body of the vernier calliper. Depending on the usage, the reading on the main scale could be either in centimetres or millimetres. 1 mm is the lowest main scale division according to the SI units. The main scale is stationary.
The first step is to measure nothing through which we can check if the main and the vernier scales are aligned.
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.
Next, look for the point on the vernier scale, which is aligned with the main scale, which gives the vernier scale reading.
It is important to note that the readings will most of the time be in decimals.
The number before the decimal point is the main scale reading, while the number after the decimal point is the vernier scale reading.
