with the help of a labelled diagram explain how is the negative zero error of a screw gauge determined also explain how such an error corrected

Expert Answer:

There are two kinds of zero error—positive and negative zero error.

1. Positive zero error: The zero error is said to be positive when the zero mark of the circular scale is lower than the base line of the main scale.
2. Negative zero error: The zero error is said to be negative when the zero mark of the circular scale is higher than the base line of the main scale.
