Determination of the Pressure Coefficients of High Precision Standard Resistors

P.P. Capra, F. Galliana

Abstract

In this paper is presented a system, developed at IEN, for determination and measure of pressure coefficients of high precision standard resistors used to maintain the unity of dc electrical resistance, and to transfer the traceability during the periodic international key comparisons established to verify the degree of equivalence of standard among different National metrological Institutes results (NMIs). Preliminary results of the utilisation of the system for the characterisation of high precision standard resistors vs. environment pressure are also given.
