Problems solved by technology

The traditional manual test is to load and run the module on the watt-hour meter, run a certain electrical appliance, and then read the module load identification result through the watt-hour meter to verify, but this method has low test efficiency, and the types of test appliances are single. Long time, not suitable for batch testing

Moreover, with the large-scale promotion and application of such smart energy meters and identification modules, the demand for identification modules is gradually increasing, and the defects of manual testing are becoming more and more obvious. Module manufacturers also need an efficient testing method to Ensure timeliness and reliability of supply
