Problems solved by technology

[0003] However, because the power meter has many measurement functions and involves many technical problems, the tester must set the standard output value of the standard signal source on the one hand, and perform manual operations on the power meter panel on the other hand. There are many operation steps, error-prone, low efficiency, not suitable for large-scale batch production, and cannot guarantee the quality of power meters

Embodiment Construction

[0019] The present invention connects the RS232 to RS485 converter externally through the two COM communication ports of the upper computer, and communicates with the standard signal source and the power meter respectively, and the standard signal source is controlled by the compiled monitoring program to automatically send out the standard output signal, and then through the power meter The communication interface transmits the measured value of the power meter back to the monitoring program, and the monitoring program analyzes and compares the received measured value and automatically judges whether the test meter is qualified or not, thus greatly reducing the work intensity of the operator and reducing the operating cost. The error rate of personnel in testing improves the production efficiency and ensures the quality of the products.
