摘要

Reference resistors are affected by the heating of the resistor element caused by the measurement current. The effects of such loading are complex and can change in magnitude as a function of the initial state of the resistor and the external environment. This paper describes a method for determining relative load coefficients by using cryogenic current comparator ratio measurements in a two-step scaling process. Previously undiscovered loading effects are analyzed using a resistance element made from copper, which has an easily measured change of resistance with temperature. The magnitude of loading effects in several types of resistors are listed.
