| Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. | |||
| Note 1: | A calibration may be expressed by a statement, calibration function, calibration diagram, calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of the indication with associated measurement uncertainty. | ||
| Note 2: | Calibration should not be confused with adjustment of a measuring system, often mistakenly termed “self-calibration”, nor with verification of calibration. | ||
| Note 3: | Often, the first step alone in the above definition is perceived as being calibration. | ||
