REPRESENTING METROLOGICAL TRACEABILITY IN DIGITAL SYSTEMS253 KB

When metrological traceability is considered in the context of modern digital systems, a model of the staged collaborative nature of traceable measurements emerges. The key elements of this model are instances of external factors that influence the measurement, and intermediate measurement stage results. Digital implementation of the uncertainty calculation method described in the Guide to the expression of uncertainty in measurement (GUM) requires unique identification of individual influence factors and intermediate results. Systems using the model presented here can implement more rigorous GUMcompliance and provide more valuable data than is currently possible to consumers of traceable measurements.
