US 2014/0278176 A1 · PORTABLE DIGITAL POWER ANALYZER

Abstract

A method includes measuring a magnetic field generated by an electrical wire using a three-axis magnetometer disposed within a portable electronic device. The device then determines a first magnetic field strength component aligned with a first direction and a second magnetic field strength component aligned with a second direction. The position of the electrical wire relative to the magnetometer is movable in the first direction, and wherein the position of the electrical wire is constrained in the second direction. The device then provides an instruction via a display to move the wire to a position where the first magnetic field strength component is equal to the second magnetic field strength component.

A method comprising:

measuring a magnetic field generated by an electrical wire using a three-axis magnetometer disposed within a portable electronic device;
determining a first magnetic field strength component aligned with a first direction;
determining a second magnetic field strength component aligned with a second direction that is orthogonal to the first direction;
wherein the position of the electrical wire relative to the magnetometer is movable in the first direction, and wherein the position of the electrical wire is constrained in the second direction;
and
providing an instruction via a display associated with the portable electronic device to move the wire to a position where the first magnetic field strength component is equal to the second magnetic field strength component.
