Abstract
An electrical circuit testing device is provided, comprising a case, a digital voltage level testing circuit with a display means, a switch to initiate measurement using the device, a non-shorting switching means for selecting pre-determined electrical wiring configurations to be tested in an outlet, a terminal block, a five-pole electrical plug mounted on the case surface and a set of adapters that can be used for various multiple-pronged electrical outlet configurations for voltages from 100–600 VAC from 50–100 Hz.
Claims11
A electrical circuit testing device, comprising:
- a case, said case having surfaces consisting of a top surface, a bottom surface, a front surface, a rear surface and side surfaces connecting said top and bottom surfaces, said case comprising a display means on one of said surfaces, a non-shorting switching means on one of said surfaces, an initiator switch on one of said surfaces, and a five-pole electrical plug on one of said surfaces;
- a digital voltage level testing circuit, said digital voltage level testing circuit connected to said non-shorting switching means and connected to said display means;
- switching circuitry for testing wiring combinations, said switching circuitry electrically connected to said non-shorting switching means and a terminal block, said terminal block connect to said five-pole electrical adapter connector;
- and
- an adapter, said adapter having at one end a five-prong adapter plug for insertion into said five-pole electrical adapter connector on one of said surfaces on said case and at the other end having a multi-prong plug, said adapter capable of being plugged into an electrical outlet and transmitting voltages greater than 100 V.
