Calibration (of a measuring instrument):
A set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realized by standards.


  • The result of a calibration permits either the assignment of values of measurands to the indications or the determination of corrections with respect to indications.
  • A calibration may also determine other metrological properties such as the effect of influence quantities.
  • The result of a calibration may be recorded in a document, sometimes called a calibration certificate or a calibration report.

Adjustment (of a measuring instrument):

Adjustment may be automatic, semiautomatic or manual.
