Question

causes of zero error in vernier callipers​

Answer 1

Answer:

Zero error means when 0th devision of main scale is not coinciding with tha 0th devision of Vernier scale when two jaws of Vernier touching each other. So there will be error due to Zero so that's why it is called as Zero error.

Answer 2

A Vernier calliper is an instrument used for making very accurate linear measurements. ... When there is no zero error, the main scale zero coincides with Vernier scale zero when there is no space between the blades. There can be two kinds of error if it doesn't coincide: positive or negative.
