A person typically performs a calibration to determine the error or verify the accuracy of the DUT’s unknown value. The results obtained by calibration are traceable to the International System of Units (SI) using unit standards and fundamental physical constants stored by national metrology institutes.
Calibration has a wide range of practical applications in various industries. It allows manufacturing or trading companies to identify measurement deviations (thus saving production costs), avoid errors in the construction sector, and build consumers’ trust when purchasing services or goods. For laboratories, calibration is the only way to ensure metrological traceability.
