Electrical Test Apparatus

An electrical test apparatus that is adapted to be removably engaged and in electrical communication with an electrical power terminal, said electrical test apparatus comprising:

• (a) analytical circuitry operative in each of a plurality of modes that include voltages, frequencies, three phase circuit rotations, ground conditions, and neutral conditions to monitor the electrical power terminal and produce a plurality of event marker signals;
• (b) criterion circuitry operative in each of said plurality of modes that include voltages, frequencies, three phase circuit rotations, ground conditions, and neutral conditions to receive each of said plurality of event marker signals for a comparison with a selected value for each of said plurality of modes, wherein said criterion circuitry outputs a plurality of indicator signals each corresponding to one of said plurality of modes;
• and
• (c) a means for producing an associated perceptible output in response to each of said plurality of indicator signals.
