Abstract :
The paper discusses systematic errors in the AC-DC difference determination resulting from the comparison of thermal voltage converters with different input connectors. Tests of the internal Tee of the calorimetric thermal voltage converter, as well as, two asymmetrical Tees, with GR-874 and type-N arms, are presented.
