1. A graduated scale whose increments are fractionally smaller than those on the scale it slides along, allowing very precise readings to be taken by noting which two marks on the scales are most closely aligned. Also called vernier scale.
2. An auxiliary device designed to facilitate fine adjustments or measurements on precision instruments.
Of, relating to, or having a vernier.

[After Pierre Vernier (1580?-1637), French mathematician.]


1. (Mechanical Engineering) a small movable scale running parallel to the main graduated scale in certain measuring instruments, such as theodolites, used to obtain a fractional reading of one of the divisions on the main scale
2. (Mechanical Engineering) an auxiliary device for making a fine adjustment to an instrument, usually by means of a fine screw thread
3. (Mechanical Engineering) (modifier) relating to or fitted with a vernier: a vernier scale; a vernier barometer.
