For high-resolution applications, a 10 mΩ rheostat may be added for the lowest step of the decade resistor. The rheostat is a 20 µΩ resolution “decade”. In order to eliminate contact resistance and thermal emf, the HARS-LX integrates the rheostat in such a way that the wiper is in the low potential circuit. As a result, voltage and contact resistance effects are removed by being effectively added to the input impedance of the measuring instrument.
