Calibration of the standard resistors by means of the standard capacitors and precise digital voltmeters

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.
