Abstract
This invention relates to the modification of a moving magnet type of a direct current reading meter wherein by the addition of an electro-magnetic coil, the permanent magnet of the meter is influenced by the magnetic field of the coil with respect to the current flow to provide a reading to indicate full scale values of a much lower current value than that of the basic movement of the meter.
