Calibration - Wikipedia

OverviewBIPM DefinitionModern calibration processesInstrument calibration promptsBasic calibration processHistorical developmentIn measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, a sound tone, or a physical artifact, such as a meter ruler. The outcome of the comparison can result in one of the following: no significant error being noted on the device underGet price
