Measurement of Resistance Standards by a Precision LCR Meter at Frequencies up to 2 MHz

Summary:We report on two-terminal-pair and four-terminal-pair test measurements of a 10-kohm resistance standard by means of a commercial precision LCR meter at frequencies up to 2 MHz. In the case of a two-terminal-pair configuration, we demonstrate that the effect of 2.5 m long measuring cables, which are inevitable for some special applications, can be corrected in the whole frequency range up to 2 MHz with an uncertainty of 9E-6 (k = 1) relative to the dc resistance value. Furthermore, the systematic effects of the LCR meter were investigated. Though distinctly larger than the resolution of the LCR meter, these effects are accurately reproducible. As such it should be possible in the future to calibrate the LCR meter against a well-known calculable high-frequency resistance standard with an uncertainty close to the few-parts-per-million type-A uncertainty of the LCR meter.
