The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.
A vernier caliper does not easily lose its calibration, but a sharp impact or accidental damage to the measuring surface in the caliper jaw can be significant enough to displace zero. [29] Digital calipers have zero set buttons, for quick recalibration. Vernier, dial and digital calipers can be used with accessories that extend their usefulness.

[10] Vernier measures in infants and non-verbal children can be done using the preferential-looking technique [11] or by electrophysiological techniques. [12 ...
