Classification: CPC G | IPC G

Claim 0:
1. An electrical parameter measurement device, comprising:
a front end that includes an opening that is sized and dimensioned to receive a conductor under test;
a plurality of magnetic field sensors disposed around the opening, the plurality of magnetic field sensors comprising a first set of magnetic field sensors positioned at a first radial distance from a center of the opening, and a second set of magnetic field sensors positioned a second radial distance from the center of the opening, the second radial distance being greater than the first radial distance, and each magnetic field sensor in the first set is radially aligned with a corresponding magnetic field sensor in the second set; and
control circuitry operatively coupled to the plurality of magnetic field sensors, the control circuitry being configured to:
receive sensor signals from the plurality of magnetic field sensors;
determine a physical position of the conductor under test within the opening of the front end based at least in part on the sensor signals;
determine a position-dependent calibration factor based at least in part on the physical position of the conductor under test within the opening of the front end of the electrical parameter measurement device; and
apply the position-dependent calibration factor to determine a current parameter of the conductor based at least in part on the sensor signals and the physical position.
