Under the background of human society entering the era of the knowledge economy and the rapid development of information technology, instrument, and their measurement and control technology are increasingly widely used, which provides a good opportunity for the rapid development of the instrument and instrument industry. Instrumentation is the source and component of the information industry and the important foundation of information technology. The international information production industry is classified into three industries: computer, communication, and instrument.
Instruments and meters are widely used in measuring and controlling the technological process of equipment and the transformation of traditional industries. They are an important part of modern large key sets of equipment and an important link for informatization to drive industrialization.
Through the instrument interface, engineers can intuitively view and understand the problems between electromechanical systems. These instruments capture, analyze, and display data, allowing the back office engineer to monitor and control the machine and make all necessary corrections. During testing or prototyping, the instrument can implement circuit improvements that create new and better designs.
This paper focuses on the application characteristics of these instruments in electricity meters

With the combination of automation technology and power system verification device, there are mainly the following products in the electric energy meter automatic verification system market:

Automatic Verification System For Single-Phase Watt-Hour Meter:

Single-phase watt-hour meter automatic verification system in a whole system for single-phase meter (including remote fee control meter, local fee control meter) to achieve the appearance inspection, voltage, power consumption, multi-function verification, key programming, verification card, labeling, and other functional items collinear test pipeline. It realizes the operation of the automatic upper and lower meters, receiving and dismantling verification, sorting logistics, and transportation, and solves the low-efficiency problem of traditional verification and storage method for large quantities of electricity meters.

Automatic Calibration System For Three-Phase Electricity Meters:

The automatic verification system of a three-phase electric energy meter can automatically realize the functions of meter warehouse connection, container disassembling and stacking, container loading (discharging) or taking out (feeding), identification, positioning, sewing disassembling, detection, labeling, meter sealing, sorting of qualified and unqualified meters, transmission control and so on.
