The invention provides an electric energy meter and acquisition terminal integrated testing device. The electric energy meter and acquisition terminal integrated testing device comprises the components of a signal source, a standard power resource, a standard electric energy meter, a network switch, a master control computer and a meter hanger. A to-be-tested acquisition terminal and a to-be-tested electric energy meter are hanged on the meter hanger. The to-be-tested acquisition terminal communicates with the network switch through a communication module. The master control computer is connected with the to-be-tested acquisition terminal and the signal source and is used for respectively transmitting DL/T 645 2007 instruction and control instruction to the to-be-tested electric energy meter and the signal source. The signal source makes the standard power source output a standard value which comprises a voltage value and a current value to the meter hanger according to the control instruction. The standard electric energy meter monitors the current value and the voltage value which is output from the standard power source. The to-be-tested electric energy meter generates corresponding data and events according to the instruction and/or the standard value. The to-be-tested acquisition terminal reads the data and the event which are generated by the to-be-tested electric energy meter and transmits to the master control computer. The master control computer simultaneously tests the to-be-tested electric energy meter and the to-be-tested acquisition terminal according to information which is transmitted from the to-be-tested acquisition terminal.
