Current tester
First Claim
1. A current tester for parasitic current leaks comprising:
- a probe,a computing device for converting a voltage drop across a fuse to a current, the voltage drop is associated with the parasitic current leak, said computing device operatively associated with said probe,an input device for selecting among multiple fuses types, said input device operatively associated with said computing device, each fuse type having a pre-determined voltage drop/current relationship stored in said computing device, andan output device for signaling a presence or non-presence of the parasitic current leak, said output device operatively associated with said computing device.

Abstract
A current tester includes: a probe, a computing device for converting a voltage drop across a component to a current, and an output device for signaling a presence or non-presence of current. The computing device stores a pre-determined voltage drop/current relationship for the component. A method for detecting current in a circuit includes: connecting a current tester to the component, measuring a voltage drop across the component, converting the voltage drop to a current via the current tester, and producing a signal by the current tester indicating a presence or non-presence of current in the circuit. A method for detecting current in a circuit may also comprises: connecting probes of a testing device to a component in the circuit; determining via whether the probes are properly connected to the component; and determining a voltage drop across the component to determine the presence or non-presence of current.
