Question

What is meant by zero error of a vernier
callipers ? How is it determined ? Draw neat
diagrams to explain it. How is it taken in account
to get the correct measurement ?​

Answer 1

Answer:

Due to mechanical errors, sometimes the zero mark of the vernier scale does not coincide with the zero mark of the main scale, the vernier callipers is said to have zero error. It is determined by measuring the distance between the zero mark of the main scale and the zero mark of the vernier scale.
