Povzetek

Calibration of measuring instruments in the industry is a process that is done regularly both internally by internal laboratories operating within the companies and externally by accredited external laboratories. The goal of the diploma thesis was to document and carry out the calibration process of a production line within a manufacturing plant, and to deliver a final report on the overall calibration. The result is obtained by calculating the combined uncertainty of the measurement process. As any measurement is gathered certain uncertainties are bound to influence the measurements, in our case we have three main uncertainties which are the standard uncertainty, uncertainty due to the resolution of the measuring instrument and the uncertainty from the calibration certificate from the measuring equipment that is used in the measurement process. The final combined uncertainty is calculated with the standard uncertainty which has a 68% confidence that the true value lies within that range therefore we need to expand the range to obtain a 95% confidence and we achieve this by multiplication of the combined uncertainty with the K = 2 factor.

Sekundarni povzetek:	Kalibracija merilnih instrumentov v industriji je proces, ki ga redno interno izvajajo laboratoriji v podjetju in zunanji akreditirani laboratoriji. Cilj diplomskega dela je bil dokumentirati in izvesti postopek kalibracije proizvodne linije v proizvodnem obratu ter izdelati končno poročilo o celotni kalibraciji. Rezultat kalibracijske meritve dobimo z izračunom skupne negotovosti merilnega postopka. Ko so vsemeritve zbrane, določene negotovosti prav gotovo vplivajo na meritve. V našem primeru vplivajo tri glavne negotovosti. Te negotovosti so: standardna negotovost, negotovost zaradi ločljivosti merilnegainstrumenta in negotovost, ki jo določa potrdilo o kalibraciji merilne opreme, ki se uporablja za kalibracijo. Končna kombinirana negotovost meritev se izračuna s standardno negotovostjo, ki ima 68-odstotno zaupanje, da je prava vrednost znotraj z negotovostjo določenega območja. Da bi dobili 95-odstotno zaupanje, moramo območje razširiti. To pa dosežemo z množenjem kombinirane negotovosti z vrednostjo 2.
