Abstract
A device is provided for measuring the voltage and energy between the contacts of a male connector from a piece of electronic equipment after it has been disconnected for a given period of time from a source of AC power. The device has both a voltage meter and a milli-joules meter which are connected into any one of a series of four circuits. In the first circuit, the meters are connected across the high voltage contact and the low voltage contact of the male connector. In the second circuit, the meters are connected across the high voltage contact and the safety ground, in the third circuit the meters are connected across the low voltage contact and the safety ground, and in the fourth circuit the meters measure the residual voltage and energy between the tip of a conductive probe and safety ground. A control element controls a relay to connect or disconnect the meters into the circuit selected after the piece of equipment being tested has been disconnected from a source of power for a given period of time.
