Vernier caliper scales; main at top, vernier at bottom. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). The main scale reading is that 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.
Caliper is the American spelling, while calliper (double "L") is the British spelling. A single tool might be referred to as a caliper or as calipers — a plural only (plurale tantum) form, like scissors or glasses. Colloquially, the phrase "pair of verniers" or just "vernier" might refer to a vernier caliper.
For example, a measurement of 5.783 millimetres would be obtained by reading 5.5 millimetres on the sleeve, and then adding 0.28 millimetre as determined by the thimble. The vernier would then be used to read the 0.003 (as shown in the image). Inch micrometers are read in a similar fashion.
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 skinfold caliper is a handheld instrument used to pinch and measure the width of a skinfold in millimeters. Calipers are used by fitness coaches and trainers as well as medical professionals in ...
Calorimeters are called active or heated if they heat the sample, or reformulated: if they are gauged to fill the sample with a defined amount of entropy. Actinometer heating power of radiation. Constant-temperature calorimeter , phase change calorimeter for example an ice calorimeter or any other calorimeter observing a phase change or using a ...
A caliper log is a well logging tool that provides a continuous measurement of the size and shape of a borehole along its depth [1] and is commonly used in hydrocarbon exploration. The measurements that are recorded can be an important indicator of wash-outs, cave ins or shale swelling in the borehole, which can affect the results of other well ...
The diameter of an object measured with a caliper is sometimes called the caliper diameter; it is the same as Feret diameter. Feret diameter applied to a projection of a 3D object. The Feret diameter or Feret's diameter is a measure of an object's size along a specified direction. In general, it can be defined as the distance between the two ...
