Research abstract
This SBIR deals with developing a commercial AC Resistance-Ratio Bridge based on research work done by R. D. Cutkosky at NIST during the 1980's. His initial work will be extended by this Phase 1 project to allow for a new state-of-the-art product design and development. The product, the Model 8686 Precision Resistance-Ratio Bridge, will have an operating current range from 0.1mA to 10mA user selectable. It will have two measurement ranges: a 40-ohm range (with 0.1uohm sensitivity) and a 400-ohm range. The unit will be able to work from any line voltage worldwide. The Model 8686's intended use is in the standards industry for measuring Platinum Resistance thermometers on the International temperature scale 1990 (ITS-90).
