Umm..I need help with vernier calipers!?

Question

Can someone plz tell me the precautions that should be taken when using the vernier caliper.

Answer 1

A caliper must be properly applied against the part in order to take the desired measurement. For example, when measuring the thickness of a plate a vernier caliper must be held at right angles to the piece. Some practice may be needed to measure round or irregular objects correctly.

Accuracy of measurement when using a caliper is highly dependent on the skill of the operator. The caliper's jaws must be forced into contact with the part being measured. A consistent, firm touch is correct.
