Question

what do you understand by the zero error of a measuring instrument ​

Answer 1

Answer:

Zero error is defined as the condition where a measuring instrument registers a reading when there should not be any reading. In case of vernier calipers it occurs when a zero on main scale does not coincide with a zero on vernier scale. If the zero line of a measuring instrument does not coincide with the index line. The instrument is said to have a zero error. By knowing the zero error, the reading taken by the instrument can be corrected.
