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.
The standard for a caliper is usually a constant of 0.02 Vernier caliper scale with the normal 0.02 vernier constant, showing measurement of object at 19.44 mm to two decimal places The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object.
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 ...

A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal , which can then be decoded into position by a digital readout (DRO) or motion controller.
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. Similarly, the inch scale shows (15 5 / 8 )/16, or 125/128, of an inch.
