Calibration is mainly used in measuring instrument technology, but also for peripheral devices that must meet the given specifications in their accuracy, color adjustment, contrast and brightness.

Calibration is used to adjust the measurement accuracy of a measuring device to the manufacturer's specifications. It describes the error limits of a measuring device at the time of calibration. The calibration makes no statement about the change of the error limits, which can occur with the time. This aspect is important, because the quality control of production and manufacturing can be affected by shifting the error limits beyond the manufacturer's specifications.

Differentiation of measurement precision

When calibrating measuring instruments, they are calibrated by means of reference quantities. Calibration refers to the accuracy of the absolute measured value. The relationship between the indicated and the actual measured value is established by reference values of measurement standards. It is therefore the comparison between the measured values of the measuring instrument and those of the reference or measurement standard or calibrator.

Calibration is dealt with in ISO 17025 and in DIN 1319-1, with DIN describing the fundamentals of measurement technology. The German Calibration Service(DKD) represents accredited member companies of the calibration industry.
