Abstract :
Four different methods used to establish traceability of AC-voltage in the mV-range are discussed. From a reference level based on multijunction thermal converters, voltage step-down is made using thermal voltage converters, micropotentiometers and resistive voltage dividers. A method based on summing of AC-voltages is also used. The results of the different methods are compared and found to be in good agreement.
