AbstractA new current-comparator-based dual-channel calibration system for AC voltages in the millivolt range for operation at power frequencies has been developed. The range of generated voltages is 1 mV - 100 mV. The calibration system in-phase and quadrature expanded measurement uncertainties (k=2) are estimated to be within 25·106. The traceability to SI units is established through the calibration of standard resistor, capacitor, and current comparator ratios.
