Calibration is the comparison of a measured value with the correct value under specified conditions, the documentation of the deviation, the calculation of the measurement uncertainty and the creation of the calibration certificate.

Blackbody calibrators are used as reference temperature sources for the calibration of pyrometers, infrared thermometers and infrared temperature sensors.

Calibration capability
The calibration capability of pyrometers, infrared thermometers and infrared temperature sensors is determined prior to calibration by means of quality, visual and functional tests.
If these tests reveal that there is something wrong with the measuring device in question, it must not be calibrated.

Calibration result:
The measured values documented during the calibration process and the values calculated from them (mean value, deviation, measurement uncertainty) are the main components of the calibration result and are documented in the calibration certificate.
A complete calibration result consists of the reference value, actual value, deviation, tolerance and measurement uncertainty. In addition, the room temperature and humidity are specified as ambient values.
