- Abstract:
- The physical model for the subdivision of the kilogram into the decade from 1 kg to 100 g was adapted for the measurement system where weight support plates have to be used. That is the case when combinations of weights with different nominal masses are compared. For this purpose the calibration procedure was modified to eliminate the unknown masses of the support plates. The equation was derived to take into account various influences on the measured mass differences. The influence of the plates on the measurement uncertainty budget and on the estimates of unknown masses of weights was studied into the decade. The analysis of results shows that the application of the support plates influences the measurement uncertainty to a small extent and also confirms the adequacy of the used model.
