Abstract :
A proposal for a new electrometric method for high precision ac/dc transfer measurements is described It is based on a high resolution analytical balance and on a suitable automatic control of the distance and the parallelism between the electrodes detected by means of capacitive sensors. Possible sources of ac/dc transfer difference are identified and an evaluation of their effects is reported.<>
