Retrospective Theses and Dissertations
This report is an analysis of the Model RT-2 Microhmmeter which is a portable apparatus using a pulse current power source in the measurement of load resistances in the microhm range. The need for accurately measuring resistances in the microhm range is quite real for testing electrical power circuit breaker contact resistance. Both during acceptance checking within the manufacturing process and in the field for preventative maintenance, contact resistance must be accurately determined. Before the invention of the Model RT-2 Micrometer, no device existed which could accurately measure resistances in the microhm range that was readily transported by an unaided …
