Abstract :
The paper describes improvements in the determination of the ac-dc transfer difference of an electronic low-voltage transfer standard (LVTS). Expanded calibration uncertainty in the 10 Hz-1 MHz frequency range and 2 mV-100 mV voltage range has been estimated to be less than 100 μV/V. Improvements have been achieved by modification of the step-down procedure that does not require loading error corrections and careful examination of the error sources
