Zumbach: self-calibration of measuring units increases accuracy of measurements

摘要

Calibration in measurement technology means establishing the measurement deviations on the measuring unit. During the calibration, no technical intervention occurs at the measuring instrument, as opposed to adjusting, where a measuring instrument is set or adapted to keep the measurement errors as small as possible or that the number of measurement errors do not exceed the error limits. The official calibration of a measuring unit is carried out according to the rules & regulations of the examining authority and the unit is marked with the respective stamp. The examining authority establishes whether the respective measuring unit fulfils the respective prerequisites.
