Abstract :
The calibration is carried out by measuring the ratios of voltages on an auxiliary resistor, once as a result of the current flowing through the previously calibrated capacitance standard, and the other time as a result of the current through the resistance standard. Using these voltage ratios, obtained with DC and low frequency AC current, measured by the precise digital voltmeters, a resistance standard can be calibrated with the uncertainty of 0.2 ppm.
