The present invention pertains generally to a corded probe for use with a measuring device that allows a user to simultaneously observe the status of a measured electrical property and provide control inputs remote from the measuring device while taking measurements in locations that may be difficult to reach and methods of using the same.
Metering instruments, such as multimeters, volt meters, bond meters, thermometers, and the like, are useful for measuring electrical properties such as current, resistance, impedance, continuity, and temperature. When using measurement instrumentation for servicing or maintaining equipment, there are often situations where the location of the desired measurement is difficult to reach. There are also situations where it is difficult for the technician to reach the measuring location while simultaneously observing the instrument display to ascertain the desired reading. Conventional measuring instruments utilize often use probes attached to the metering device, but the display or other indicators are located on the metering device itself. If the technician is in an environment where the display is not easily accessible, it may not be possible to determine readings in real time.
When making probed measurements using corded probes, such as required when measuring resistance and impedance, there is a need to provide some control input to the measuring instrument, for example, hold the reading, send the reading to a remote database, etc. When the probe operator is working in a confined space, access to the panel controls of the measuring instrument are often limited, and the operator may not be able to easily reach a control input on the instrument. The operator typically has to blindly try to keep the probe in contact with the electrical contacts and turn back to the measuring instrument to make control inputs leading to inaccurate readings.
Further, certain status or alarm indications such as “measurement good”, “reading outside normal limits”, “broken wire”' etc., are valuable information to the probe operator. These indications are normally presented by means of lamps located on the measuring instrument front panel, which will not be visible to the operator when they are remote-probing in a confined space. Once again, the operator must blindly try to keep the probe in contact with the electrical contacts and turn back to the measuring instrument to observe status or alarm indications of the device being tested.
Therefore, there is a long felt need in the art for a device with a display and input devices integrated into a probe that provides critical information at the measuring point. Further, there is a long-felt need in the art for a system for remotely observing the status of a measurable electrical property. There is also a need for a method of remotely controlling input to the measuring instrument while measuring the status of an electrical property.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

The measuring instrument may be any instrument configured to generate or measure an electrical property, such as, but not limited to, multimeters, volt meters, bond meters, thermometers, continuity testers, humidity meters, and the like in a device having an unknown electrical status to be measured. Measurable electrical properties or parameters may include, electrical current, voltage, resistance, power, capacitance, inductance, temperature, and the like. The wired probe assembly is configured to allow an operator to take measurements in difficult to reach or remote areas while simultaneously observing a status of the measured electrical property in real time when the operator cannot see a display of the measuring instrument. Additionally, the operator can provide inputs to the measuring device remotely via the wired probe assembly.

The measuring signal element 134 is typically a plurality of wires that electrically connect the measuring input 124 to the measuring instrument 10. The measuring instrument 10 then receives signals from the measuring input 124 via the measuring signal element 134 and determines a measurement, then uses the user interface control element 132 to transmit the information to the display element 114 and the visual indicator 114 at the point of measurement. The operator may provide inputs to the measuring instrument 10 using the at least one input element 106 to transmit a signal via the user interface control element 132.
