Calibration in measurement technology and metrology is the process of comparison of measurement values delivered by a device under test with 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, or a physical artefact, such as a metre ruler.
The outcome of the comparison can result in no significant error being noted on the device under test, a significant error being noted but no adjustment made, or an adjustment made to correct the error to an acceptable level. Strictly, the term calibration means just the act of comparison, and does not include any subsequent adjustment.
The calibrating standard is normally traceable to a national standard held by a National Metrological Institute and can be a physical artefact for direct measurement, a custom built device for indirect measurement, or a similar device to that which is under test.
