Claim 17:
18. A method of operating an electrical parameter measurement device, the method comprising:
placing a conductor under test in an opening of a support member of the electrical parameter measurement device;
sensing one or more electrical parameters of the conductor under test, wherein the sensing comprises using a 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 at 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;
receiving sensor signals from the plurality of magnetic field sensors;
determining a physical position of the conductor under test within the opening of the support member, wherein the determining is performed based at least in part on the sensor signals;
determining 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
applying the position-dependent calibration factor to determine a current parameter of the conductor based at least in part on the one or more electrical parameters sensed and the physical position.
