(EP1107009-A1)   NOVELTY - The input terminals of differential voltage amplifier (10) are connected to conductors at opposite ends of segment (12). A microcontroller (22) converts the output voltage value of the amplifier into electrical current value and is connected to electrically erasable programmable read only memory (EEPROM) (20) that stores calibration table in digital form.    USE - For measuring AC or DC current flow in the conductor, used in vehicle to measure battery current.    ADVANTAGE - Since the microcontroller is connected to memory that stores calibration table, the output voltage value of amplifier is correctly converted to current value. The cutting of cable is avoided, since the amplifier is connected conductor at ends of segment.
