Embodiment Construction

[0032] The present invention is an automatic verification system, method and application of a digital multimeter based on the integration of meter and source. The integration of meter and source means that the verification device can be used as both a source and a standard meter. The system mainly includes upper computer, digital multimeter automatic verification system software, three-phase AC and DC verification device, RS232 or IEEE488 communication line; the upper computer is connected with the three-phase AC and DC verification device through RS232 or IEEE488 communication line in communication mode. The three-phase AC-DC verification device includes a three-phase AC source, a DC source, a standard meter, an error analyzer, a remote console, and the like.

[0033] For the complexity of current digital multimeter verification, the present invention includes the following four verification methods:

[0034] (1) Standard source inspection table mode:

[0035] Such as figur...
