System and method for verifying failure detect circuitry in safety compliance test instruments
First Claim
1. A verification method for a safety compliance instrument, to check whether the safety compliance instrument will detect failure by a product to pass a safety compliance test, comprising the steps of:
- displaying a verification test-select menu upon power-up of the instrument;
upon selection of a verification test, instructing an operator on which connections to make for the selected test, and instructing the operator on how to initiate verification by activating a test initiation input;
upon completion of the test, indicating the result of the selected verification test by displaying one of a verification successful message and a failure to verify message.

Abstract
A safety compliance test instrument includes a display capable of displaying prompts, a menu display program, software for displaying a plurality of instrument verification menus, prompts, and messages concerning results of the verification tests, and software for enabling or preventing safety compliance tests from being performed depending on results of the verification. The safety compliance instrument includes at least two different safety compliance tests involving different connections to a device under test. The tests may be selected from the group consisting of a continuity test, a ground test, a dielectric withstand test, and an insulation resistance test, and more specifically from the group consisting of a continuity test, a ground bond test, AC and DC dielectric withstand tests, and an insulation test. The verification system of the invention may be implemented on any test instrument having an interactive display capable of presenting a series of menus, and of having the operator select options presented by the menus, including instruments with full keyboards rather than softkeys, or with cursor control type inputs, as well as one or two line displays that require scrolling.
