The invention relates to a measurement system of an electric energy meter temperature influence test. A meter hanging rack is arranged in a temperature test box, and the meter hanging rack is provided with a relay corresponding to each row of electric meters. The operation mode of the relay is controlled by a controller. A power source voltage output end is directly connected to an electric energy meter voltage input end, a power source current output end is connected to an electric energy meter current input end through the relay, and the electric energy pulse outputted by a power meter and the standard pulse outputted by a power source are connected to the error instrument of a power source. According to the system, by using an original electric energy meter verification apparatus, the rapid switch of a multiple-type electric energy meter in the error detection of the temperature influence test, thus the temperature accuracy and stability of the temperature test box are guaranteed, the artificial wiring int
