Calibration

Set of operations that establish, under specified conditions, the relationship between values of a quantity indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realised by standards. The result of a calibration is usually recorded in a document, sometimes called a calibration certificate or a calibration report.

Note: Calibration in the mounted condition is advisable in the case of unusual measuring arrangements and/or if the measurement must meet very high requirements for accuracy. For applications in shunt mode, calibration in the mounted condition is essential.
