The UK's National Physical Laboratory, in collaboration with Fluke, recently completed a feasibility study on internet-based calibration of electrical quantities (result of which were presented at the NCSL 2000 conference). We report here a study on the performance of the 4950 multifunction transfer standard (MTS), which is central to facilitating this new route for transferring accurate traceable measurements of DC resistance and voltage. The corresponding measurement functions of the MTS have been evaluated at different environmental applied conditions, such as temperature, humidity, mains supply and warm-up times, to determine its suitability in terms of drift, stability and accuracy for providing calibration of electrical quantities via the internet.
