PEC-HA single-phase energy meter field calibrator is one of Kehui company’s series products. PEC-HA single-phase energy meter field calibrator is a kind of multi-functional modern meter calibration device designed and produced by use of large-scale programmable logic array and a series of advanced technologies and devices, with advanced technology, complete functions, compact structure, reliable performance, convenient use and other advantages. Its successful research and development provides great convenience to field energy meters and various other instruments, and it is a high-end product with excellent performance in single-phase electric energy measurement!
The single/three-phase standard energy meter is an advantageous product in our company's electric energy metering series products. With wide range measurement, the voltage terminal range is 30V~480V, the current terminal ranges from 1mA~100A, wide range current input does not need to replace the input port; good temperature coefficient 5~10ppm/℃, greatly reducing the influence of temperature changes on measurement errors.
This product is developed by our company for the uplink fault diagnosis of the terminal of the low-voltage centralized copying system. It can detect the signal strength of each standard network of the three major operators, and provide the operator and network standard with the best signal to provide judgment for the on-site personnel. in accordance with. This product integrates 3 independent signal detection channels, each channel can diagnose SIM card faults independently or simultaneously, and each channel automatically supports signal detection of the whole network and all standards (supports all standards of mobile, telecom and China Unicom detection). Each channel supports automatic detection of SIM insertion, automatic identification of SIM card information (CCID, IP, operator, network standard, etc.), automatic identification of base station location information (CELL_ID, LAC), uplink PING detection, and uplink master station login detection and other functions.
