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.

- Wht do you understand by least count of instrument?
- how dicovered screw gauage?
- Is there any advantage of screw gauge over vernier calliper or vice versa? If not why do we have 2 instruments?
