Abstract
An apparatus for measuring current carried by a conductor has a differential voltage amplifier having inputs for connection to the conductor at two spaced-apart points thereof, constituting the ends of a segment. A circuit which converts an output voltage of the amplifier into a current value incorporates a microcontroller associated with a programmable memory storing a calibration table in digital form.
