But it's obvious how to use a caliper: it's reading the vernier scale which needs instruction, and I still think that's the focus of this animation, not how to insert the nut. (Which makes me notice that the captions are wrong: the bolt is the screw-without-a-pointy-end that goes inside the nut).
A vernier scale (/ v ə r ˈ n iː ˈ ə r / ver-NEE-er), named after Pierre Vernier, is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation, thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation ...

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.
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 ...
The stopwatch is more precise at measuring time intervals than the sundial because it has more "counts" (scale intervals) in each hour of elapsed time. Least count of an instrument is one of the very important tools in order to get accurate readings of instruments like vernier caliper and screw gauge used in various experiments.
In computational geometry, the method of rotating calipers is an algorithm design technique that can be used to solve optimization problems including finding the width or diameter of a set of points. The method is so named because the idea is analogous to rotating a spring-loaded vernier caliper around the outside of a convex polygon . [ 1 ]
