Zero error in vernier caliper implies:
Select the correct option:
Solution
Incorrect! Answer:
Scale does not start at true zero
Zero Error occurs when the zero marks of the main scale and vernier scale do not coincide when the jaws are closed.
- Positive Zero Error: Vernier zero is to the right of the main scale zero. Correction is subtracted.
- Negative Zero Error: Vernier zero is to the left of the main scale zero. Correction is added.
- True reading = (Observed reading) - (Zero error with sign).
