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.

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.
Dimensional characteristics (size, shape, and feature location) are normally inspected using calibrated tools such as Coordinate Measuring Machines (CMMs), Vernier calipers, Go/no go gauges, etc. It may also be a requirement for material testing to be completed, checking the hardness, conductivity and other properties.
They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role). Gauge blocks are the main means of length standardization used by industry.
