Calibration of 10HM based on a QHR standard using a commercial DCC bridge

摘要

A calibration technique of 1 Ω based on a QHR standard(i=4 step) using a commercial DCC bridge have been described. Sample characterizations and bridge ratios have been measured using the DCC bridge without a CCC bridge and total combined uncertainty is estimated as about O.1×1O{sup}(-6) level.
