Analysis of Change of Mass Difference between Weight Support Plates during Subdivision of 1 kg

Matej Grum, Martin Terlep
Abstract:
In the research a possibility was studied how to reduce a number of repetitions of measurements when performing dissemination of 1 kg mass standard and at the same time maintain the level of confidence of the measurement results.
The method considered is designed for weighing schemes where a pair of support plates for weights is required to carry out comparisons of combinations of weights on comparators with automatic weight handler and the same pair of support plates is used for many of the compared weight combinations.
The results of analysis indicate to minor relation between the changes in mass differences of the compared weights and the changes in mass differences of the support plates. It can be seen that there is no influence on the mass of compared weights due to improper handling of the weights. The main reason for the deviations of the measurement results when using the support plates might be the performance of the comparator.
