A device and methods for detecting current changes over a preset threshold in a circuit are provided. The device includes a housing for securing at least a circuit board therein. The device further includes at least one alerting device in electrical communication with and controlled by a micro-controller. The device also includes at least one input device fixed with the housing and configured so that a user may set conditions for the micro-controller. The meter also includes at least one detecting device for measuring a current reading in a circuit, and in electrical communication with the micro-controller. The micro-controller stores a current reading in the memory and the micro-controller then compares subsequent current readings to the stored current readings to calculate a current change. If the current change is greater than the preset threshold, the micro-controller activates the at least one alerting device.
