Handheld metering fault error analyzer

The invention provides a handheld metering fault error analyzer. An input module is used for receiving output voltage signals and output current signals of an electric energy metering device. A power inspection module in a controller is used for judging and calculating the two output voltage signals and two output current signals, and comparing the two output voltage signals and two output current signals with a first preset relation, and generating an inspection result. An electric quantity compensation module in the controller is used for generating a compensated electric quantity according to the inspection result and a second preset relation. A display module is used for displaying the inspection result and the compensated electric quantity. There is no need of professional knowledge of metrology, and only two output voltage signals and two output current signals are needed for obtaining the corresponding inspection result and compensated electric quantity through the strong calculating capability of the
