DVM input and leakage resistance analysis in the DVM-based resistance measurement systems

The digit voltmeter (DVM) input and leakage resistances have been analyzed in the DVM-based resistance measurement system using one or two DVMs. The results are given both theoretically and experimentally. Shunting errors due to DVM-input and leakage resistances were substantially reduced by using a proper measurement method. The method is being further investigated for measuring high-ohm standard resistors.
