Abstract

This paper describes the ac resistance measurement system developed at CEM. It consists on a four terminal-pair coaxial bridge that allows the measurement of ac resistance with traceability to dc resistance by means of a calculable resistor with a nominal value of 10 kΩ. This coaxial bridge enables the determination of ac resistance standards between 1 Ω and 100 kΩ, in a range of frequencies from 40 Hz to 5 kHz, with an expanded uncertainty between 1 µΩ/Ω and 5 µΩ/Ω, depending on the nominal value of the resistor and the measurement frequency.
