Test Load Reference Mass Value for AWI Calibration
M. Grum, G. Grgic
Abstract:
Calibration of automatic weighing instruments in a dynamic mode of operation can not be performed directly with standard weights. It is necessary to use products or items that are normally weighed on these instruments. Several approaches are presented and discussed in the article for determination of the reference mass value of the test loads used for the calibration of automatic weighing instruments. For each presented approach uncertainty components are identified and evaluated. Finally, the indicative classification of presented methods with regard to their accuracy is carried out.
