Implementation of a Commercial Quantum Hall Resistance System

Implementation of a Commercial Quantum Hall Resistance System

May 16, 2016

This paper describes the process and implementation of a commercially available Quantum Hall Resistance System into a Primary Standards Calibration Laboratory. Topics include system design, component descriptions and verification of the sample operating characteristics, including the measurement of the QHR device in the MI 6800A system when compared to a cryogenic current comparator. (CCC) The system verification referenced is located at the Institute for National Measurement Standards (INMS) at the National Research Council (NRC), Canada. Also included is a brief description of the most recent on-site installation, the measurement results using the QHR 6800A system to establish the value of a 1 kΩ resistor and the automated measurement process from the 1 kΩ resistor up to the 10 kΩ and down to the 1 Ω value.
