| Abstract: | While measuring central value resistance with traditional voltammetry, either the internal connecting method or external connecting method of an ammeter brings system errors of measurement results. A new method of measuring resistance with the voltage compensation voltammetry principle was described. A formula of relative standard uncertainty was given, which measured resistance with internal connecting method, external method, and voltage compensation voltammetry. With comparing the uncertainty, the measurement data were processed. The measurement results of resistance, uncertainty and computing results of errors were provided. |
