Electric circuit tracer
First Claim
1. A receiver for a circuit tracer, comprising a housing, a display mounted in the housing for visually displaying information to a user, a sensor in the housing for detecting the orientation of the receiver as a whole, the display being responsive to the sensor to orient its information such that it is readable by a user and wherein the display is responsive to the sensor to rotate the information on the display in one of four 90-degree orientations so that the information is always displayed right side up.

Abstract
A circuit tracer includes a transmitter that places one of first and second signals on an electrical circuit depending on whether the circuit is energized. A receiver detects the signals imposed on the circuit by the transmitter, with the signal strength indicating the proximity of the receiver to the circuit. The receiver detects which of the transmitter signals is present and thereby can also indicate whether power is present on the circuit. The receiver has first and second antennas, one optimized for wide area detection and one optimized for circuit breaker detection. The receiver has an OLED display that remains properly oriented for viewing regardless of the orientation of the receiver housing. The transmitter can have a clamp version that inductively couples to the circuit being traced.
