- 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 small, movable auxiliary graduated scale attached parallel to a main graduated scale, calibrated to indicate fractional parts of the subdivisions of the larger scale, and used on certain precision instruments to increase accuracy in measurement. 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.
