Calibration: increased precision and reliability

Calibration involves comparing the reading of an instrument being calibrated with that of a reference instrument, under specific conditions. Other important aspects of calibration include documenting the deviation recorded, calculating the resulting measurement uncertainty and creating the calibration certificate recording this uncertainty. The calibration of measuring instruments is therefore an essential part of quality assurance, contributing to the prevention of rejects, reworking, or claims for compensation.
