Zero error
- When the fixed jaw and sliding jaw are closed, but the zero on the Vernier scale coincides with zero on the main scale. Then the Vernier calliper does not have zero error.
- When the fixed jaw and sliding jaw are closed, but the zero on the vernier scale does not coincide with zero on the main scale. Then the vernier calliper said to have zero error.
There are two types of error
- Positive error
- Negative error
Positive zero error
- Positive zero error occurs if zero on the vernier scale lies on right side of zero on the main scale.
- If the error is positive, the correction is negative.
Negative zero error
- A negative zero error occurs if zero on the vernier scale lies on the left side of zero on the main scale.
- If the error is negative, the correction is positive.
Important Points
Zero error is always subtracted from the observed readings.
