Abstract
The utility model discloses an electric energy meter detecting device. An AC (alternating current) sampling loop performs voltage and current amplitude sampling through the connection with a voltage input loop and a current input loop, and transmits the sampled digital signals, which is processed by a connected A/D converter and a DSP module, to a connected microprocessor; and the microprocessor calculates the power value and the electric energy value through the sampled digital signals from the voltage input loop and the current input loop, compares the calculated power value and the calculated electric energy value with the power value and the electric energy value which are calculated through electric meter impulses received from two connected electric energy impulse input interfaces, and then displays the comparison result through a connected error display. The electric energy meter detecting device can detect two electric meters at the same time on field, and display the detected error through the display, so that the time is cut by half and the efficiency is doubled compared with the prior art which has electric meter detection respectively.
