1. A method for testing an electricity meter including a light emitting diode and an optical interface having an infrared transmitting diode, said method comprising the steps of:

  • applying a test load having a predetermined energy level to the electricity meter;

    generating a first plurality of meter pulses having a frequency corresponding to the predetermined energy level;

    dividing the first plurality of meter pulses to form a second plurality of meter pulses;

    feeding the second plurality of meter pulses to the light emitting diode;

    causing the light emitting diode to generate a visible display representing the predetermined energy level of the test load; and

    transmitting a first request message to the optical interface to initiate an injection of at least one of the first and second plurality of meter pulses to the infrared transmitting diode.
