ABSTRACT:
A test instrument for determining whether an apparatus has a high voltage on the chassis thereof includes a meter, a probe and a socket for receiving a plug from the device being tested. The device also has a plug for insertion into an AC outlet. The test device first tests to determine that the AC outlet into which it is plugged is properly configured, then tests for a voltage on the chassis of a tested apparatus. The test is undertaken by connecting both the high and low contacts of the plug from an apparatus to be tested to the high voltage side of an outlet and connecting the probe to the ground contact of an outlet. Thereafter, when the probe is touched to the chassis of the apparatus the meter will indicate whether a voltage is present on the chassis of the appliance.
