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.
The calipers in the diagram show a primary reading on the metric scale of about 2.475 cm (2.4 cm read from the main scale plus about 0.075 cm from the vernier scale). Calipers often have a "zero point error": meaning that the calipers do not read 0.000 cm when the jaws are closed.
English: Illustration of a vernier caliper. The caliper is showing a measurement of 2.475 cm ± 0.005 cm. Legend: Outside jaws: used to measure external length; Inside jaws: used to measure internal length; Depth probe: used to measure depth; Main scale (cm) Main scale (inch) Vernier (cm) Vernier (inch) Retainer: used to block/release movable part
Using a vernier caliper to take measurements on a nut. The 1st two digits are decided by the location of the 0 on the lower scale. The last digit is determined by the 1st line on the lower scale that exactly matches the upper scale.
Vernier micrometer reading 5.783 ± 0.001 mm, comprising 5.5 mm on main screw lead scale, 0.28 mm on screw rotation scale, and 0.003 mm added from vernier. Some micrometers are provided with a vernier scale on the sleeve in addition to the regular graduations. These permit measurements within 0.001 millimetre to be made on metric micrometers ...
The main scale reading is the rightmost graduation that is to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales. The 0.02 mm engraving indicates the caliper's accuracy and is the "Vernier constant" for this scale. He was born in Ornans, France, in 1580. He was ...
Vernier acuity is measured by asking participants to judge the offset between two parallel line segments with both eyes (binocular vision) or with each eye individually (monocular vision). [10] Vernier measures in infants and non-verbal children can be done using the preferential-looking technique [11] or by electrophysiological techniques. [12 ...
Vernier scale gives interpolated measurements to 1/128 of an inch Retainer : used to block movable part to allow the easy transferring of a measurement Here the metric scale shows a distance of 2.475 cm between the jaw faces: the 0 mark on the vernier is between 2.4 and 2.5, and the 7.5 mark is the one best aligned with a mark on the main scale.
