1. An electrical test device having multimeter functionality and being adapted to provide current sourcing to an electrical system for selective measurement of a plurality of parameters thereof in at least one of powered and unpowered states, the electrical test device comprising:

  • a conductive probe element configured to be placed into contact with the electrical system and provide an input signal thereto;

    a power supply interconnected between an external power source and the probe element;

    a processor electrically connected to the probe element and configured to manipulate the input signal provided to the electrical system and receive an output signal in response to the input signal, the output signal being representative of at least one of the parameters of the electrical system; and

    a display device electrically connected to the processor and configured to display a reading of the output signal, the reading being representative of the parameter;

    wherein the electrical test device is configured to allow for selective powering of the electrical system upon energization of the probe element during measurement of the parameters.
