Abstract :
The new generation of PMJTCs on quartz crystal chips and on quartz membranes developed at the Physikalisch-Technische Bundesanstalt (PTB) results in new calculable ac-dc current transfer standards for a current of 10 mA in the frequency range from 10 kHz to 1 MHz, with considerably reduced uncertainties. AC-DC current transfer differences below 1 μA/A with standard uncertainties below 1 μA/A have been achieved.
