百科释义

A vernier scale is an additional scale on a measuring device that lets the user read distance or angle measurement more accurately than could be done by reading a uniformly-divided straight or circular measurement scale. It is a sliding secondary scale that indicates where the measurement lies in between two of the marks on the main scale.
