Socket tester with switchable audible indicator of detected presence of voltage

A socket tester device, comprising:

• an electrical plug configured to be inserted into an electrical socket;
• a tester circuit electrically coupled to the electrical plug, wherein the tester circuit outputs one or more signals indicating a wiring condition of the electrical socket into which the electrical plug is inserted;
• a sound emitting device;
• a communication device;
• a processor electrically coupled to the tester circuit, the sound emitting device, and the communication device;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to:
• receive the one or more signals indicating the wiring condition of the electrical socket into which the electrical plug is inserted,
• control the communication device to wirelessly transmit a first message that includes data indicating the wiring condition of the electrical socket into which the electrical plug is inserted, and
• control whether the sound emitting device emits one or more sounds,
• wherein the electrical socket includes a first receptacle configured to be electrically coupled to a neutral voltage potential, a second receptacle configured to be electrically coupled to a hot voltage potential, and a third receptacle configured to be electrically coupled to a ground voltage potential, and
• wherein the wiring condition of the electrical socket is selected from a group consisting of:
• a first wiring condition in which the first receptacle is electrically coupled to the neutral voltage potential, the second receptacle is electrically coupled to the hot voltage potential, and the third receptacle is electrically coupled to the ground voltage potential;
• a second wiring condition in which the third receptacle is not electrically coupled to the ground voltage potential;
• a third wiring condition in which the first receptacle is not electrically coupled to the neutral voltage potential;
• a fourth wiring condition in which the second receptacle is not electrically coupled to the hot voltage potential;
• a fifth wiring condition in which the first receptacle is electrically coupled to the hot voltage potential and the second receptacle is electrically coupled to the neutral voltage potential;
• and
• a sixth wiring condition in which the second receptacle is electrically coupled to the ground voltage potential, and the third receptacle is electrically coupled to the hot voltage potential,
• wherein the instructions, when executed by the processor, cause the processor to output a first control signal that causes the sound emitting device to emit the one or more sounds with a first acoustic characteristic in response to the wiring condition of the electrical socket being the first wiring condition, the second wiring condition, the third wiring condition, or the fourth wiring condition, and
• wherein the instructions, when executed by the processor, cause the processor to output a second control signal that causes the sound emitting device to emit the one or more sounds with a second acoustic characteristic that is different from the first acoustic characteristic in response to the wiring condition of the electrical socket being the fifth wiring condition or the sixth wiring condition.

A method of operating a socket tester device that includes an electrical plug configured to be inserted into an electrical socket, a communication device, a processor, and a sound emitting device, the method comprising:

• receiving, by the processor, one or more signals indicating a wiring condition of the electrical socket into which the electrical plug is inserted;
• wirelessly transmitting, by the communication device, a first message that includes data indicating the wiring condition of the electrical socket into which the electrical plug is inserted;
• outputting, by the processor, a control signal that controls whether the sound emitting device emits one or more sounds;
• and
• wirelessly receiving, by the communication device, a second message,
• wherein the outputting the control signal that controls whether the sound emitting device emits the one or more sounds is performed in response to a value in the received second message.
