Automated Low-Ohmic Resistance Measurements at the $\mu \Omega/\Omega$ Level

A measurement setup is described, which has been developed at NMi Van Swinden Laboratorium for the automated measurement of low-ohmic resistors. It is based on a stand-alone commercial current range extender, which enables automated measurements of many low-ohmic resistors at the muOmega/Omega level. The developed software gives full insight in the measurement process
