Zumbach - ( Self ) calibration of Measuring Units Increases Accuracy of Measurements
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 and 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 .
The validity of a calibration period follows practical requirements such as manufactures information , requirements of quality standards or company internal and customer specific regulations , rather than an official calibration with a fixed time period validity for use .
Return and Calibrating Hierarchy
In order to be able to compare results of measurement , it must be possible to « feedback » information via a chain of comparison measurements to a national or international master . For this purpose , the display of the measuring unit in use or the material
