    Abstract: The situations of system errors and data updating failure exist in engineering applications. The non-consistent parameters between the merging unit and the digital electric energy meter cause these situations. This paper introduced the content of the consistency parameters of the digital measurement system in substations to conclude three different types of the non-consistent parameters of this kind of equipment in the engineering application field. This research analyzed the non-consistent parameters and obtained the fault representation phenomenon, including abnormal numerical representations of electric energy, voltage, and current. This study established a diagnosis form by choosing the fault characterization value in engineering practice. A method of diagnosis suitable for a semi-digital measurement system was designed based on the acquisition method of fault characteristic value and diagnosis form. Experiments proved the effectiveness of this method. This diagnosis method can reverse diagnose the specific causes of a non-consistent parameters by using fault phenomena. Therefore,accelerate the troubleshooting speed caused by non-consistent equipment parameters in the engineering application field.
    Key words: digital energy metering; parameter non-consistent type; fault characterization value; parameter consistency diagnosis form;parameter consistency diagnosis method
