The invention relates to a debugging method for area metering equipment diagnosis, and relates to the technical field of electric power system improvement. The debugging method for area metering equipment diagnosis comprises the steps determining the connection relationship; determining the serial port configuration; determining the debugging strategy configuration; inputting the information of concentrators; inputting the information of gatherers; calling the roll for the gatherers; and intercepting the concentrators by the gatherers. When no power failure occurs, the debugging method for area metering equipment diagnosis helps a debugging staff to perform debugging processing of the gatherers to complete intelligent diagnosis that the meters and the gatherers belong to the concentrators and to analyze the reason why the acquisition fails, so that the data acquisition success rate for an ammeter of a user is improved finally.
