Improvements in 10 Kilohm Resistance Measurements at NIST
L. L. Scott
The 10 kilohm measurement system at the National Institute of Standards and Technology has been improved. The guarded resistance bridge is based on the Warshawsky bridge model and is self-balancing through the use of a precision feedback system. A unique guarded switch was designed to automatically switch each resistor into the test arm of the bridge. The graphical user interface program allows the system to be fully automated from control to calculations, so there are no transcription errors and the system is self-contained. Additionally, scaling from 1 ohm to 10 kilohm has been automated through use of a cryogenic current comparator system.
