Current monitor for indicating condition of attached electrical apparatus

摘要

A current monitor is described that indicates a condition of attached electrical equipment. The current monitor can determine a predetermined range in which current being withdrawn by the attached electrical apparatus lies. Based on the determined range, corresponding display electronic elements, such as light emitting diodes (LEDs), can be activated. Activated LEDs of a particular color can indicate corresponding conditions of the electrical equipment. For example, activation of green LEDs can indicate normal functioning of the electrical equipment, activation of one or more amber/yellow LEDs can indicate that lubrication of the electrical equipment is required soon, and activation of one or more red LEDs can indicate that lubrication of the electrical equipment is required and that the electrical equipment may not be used to avoid damage/failure due to overheating of the electronic circuitry associated with the electrical equipment. Related apparatus, systems, techniques and articles are also described.

1. A method comprising:
obtaining, at an electrical circuit and in accordance with a current requirement of an electrical equipment, current from a power source; comparing, using the electrical circuit, the obtained current with at least one of a first threshold and a second threshold; if the obtained current is less than a first threshold, activating one or more light emitting diodes of a first color; if the obtained current is equal to or more than the first threshold and is less than a second threshold, activating one or more light emitting diodes of a second color; and if the obtained current is equal to or more than the second threshold, activating one or more light emitting diodes of a third color, wherein the electrical circuit includes a latching mechanism that enables the color of the activated one or more light emitting diodes to be retained after the electrical equipment stops being used.
