- a short graduated scale that slides along a longer graduated instrument and is used to indicate fractional parts of divisions, as in a micrometeralso vernier scale
- any device that makes possible a finer setting of a tool or measuring instrument
Origin of vernierafter Pierre Vernier (1580-1637), French mathematician who invented it
of or fitted with a vernier
- 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 .
- An auxiliary device designed to facilitate fine adjustments or measurements on precision instruments.
Of, relating to, or having a vernier.
Origin of vernierAfter Pierre Vernier (1580?-1637), French mathematician
- A secondary scale with finer graduations than the primary scale of a measuring device; the vernier measures between graduations of the larger scale.
- A secondary control input with finer control than the primary, or coarse, input; for example the vernier frequency tuning knob on a radio.
- (physics) A secondary system of force application for the attitude control of a spacecraft; for example a vernier thruster.
