    Useful information The variables measured by the instrument are correct if the inputs have been connected ac- cording to the right polarities (see figure below). Should the connection not be conforming to the right polarities, measuring and retransmission errors may occur, both due to the wrong direction of the current flowing in the primary/secondary of the ammeter trans- former being connected.
