Description

BACKGROUND

1. Field of the Invention

The present invention relates generally to circuit testing systems, and more specifically, to a dual circuit current loading analysis apparatus for determining failures or defects in electrical systems such as wiring or circuits.

2. Description of Related Art

Circuit testing systems are well known in the art and are effective means to isolate breaks or flaws in electrical systems. For example, FIG. 1 depicts a conventional multi-meter device 101 having a positive probe 103 and a negative probe 105 attached to a test device 107. The test device 107 having a digital display 109 where the results are shown. During use, the probes 103, 105 are touched to various places in a circuit allowing electricity to flow creating a result that is displayed.

One of the problems commonly associated with device 101 is its limited use. For example, the multi-meter device 101 can check for continuity, voltage or current and provide a numerical result, however the device 101 does not create a full electrical load on the circuit causing diagnosis errors.

Accordingly, although great strides have been made in the area of multi-meter devices, many shortcomings remain.
