Traditionally, DC resistance measurements to sub-ppm accuracy have been performed by using a number of discrete measurement, reference resistance and temperature bath devices that were manually connected together by the test technician. These devices may have been manually controlled or provided with automated control through data acquisition software. This paper describes developments in incorporating all of the necessary hardware components and data acquisition software into one integrated DC resistance measurement system. Automated methods for verifying the accuracy of the resistance measurement system and calibrating its working standard resistances against resistance standards traceable to National Standards are presented. Automated methods for testing special resistive devices are also presented. |
