Product introduction:
The test system's control operations are based on a PLC programmable logic controller and a touch-operated integrated computer software interface. Through optimized software design, all test items can be completed automatically. The introduction of a data management system enables automatic storage of test results and generation of test reports for each test item, eliminating the need for test personnel to perform tedious operations such as recording and inputting data, thereby improving test efficiency. The system features intelligent test process control, intelligent line switching, intelligent data processing, intelligent data upload, and intelligent determination of energy efficiency levels.
