Abstract

An automated guarded resistance bridge has been specifically developed at the National Institute of Standards and Technology (NIST) for the calibration of high-quality 10 kΩ standard resistors. The system is designed to intercompare up to 30 nominally-equal, four-terminal resistors with a resolution and combined relative standard uncertainty of 0.01 μΩ/Ω and 0.02 μΩ/Ω, respectively. With a few minor modifications, the system is capable of comparing other nominally-equal resistors in the range 100 Ω to 1 MΩ
