The metroscope has been used very frequently for exercises in subject - Engineering Metrology at the bachelor study. New systematic errors have been obtained from calibration process. Other measurements have been also realized and corrections of results have been executed via using of new systematic errors. Measured errors from acceptance test have confirmed that metroscope is out of the limits defined through the maximum permissible error. Nevertheless the metroscope is fully functional and errors could be eliminated through the including of new measuring system consisting from suitable distance sensor. http://pubs.sciepub.com/ajme/2/7/21/ajme-2-7-21.pdf metrology measurement systematic error gauge blocks
