A new method on measuring the level dependence of AC shunts

We describe a method of the measurement of level dependence in AC-DC difference of current shunts. The method is based on the use of a binary inductive bridge. The measuring principle and measurement results of a 1 A AC shunt at frequencies up to 100 kHz are presented.
