A key comparison for the 10 MΩ and 1 GΩ resistance, APMP.EM-K2, has been carried out by the Asia-Pacific Metrology Program(APMP) Regional Metrology Organization(RMO). The purpose is to establish the degree of equivalence of resistance among the national metrology institutes(NMIs) within APMP, in support of CIPM Mutual Recognition Agreement(MRA). The key comparison artifacts are three 10 MΩ and three...
This paper reports the results of an ongoing bilateral key comparison at 10 kΩ resistance standards between KRISS and the BIPM. Two 10 kΩ travelling resistance standards of the BIPM were measured at KRISS against a 100 Ω transfer standard by using a homemade cryogenic current comparator (CCC) bridge system. The value of the transfer standard resistor maintained at KRISS is calibrated against the quantized...
