It allows all electrical parameters to be displayed and utilized for communication and/or output functions. Advantages Easy to use Five direct access pushbuttons enable all measurements to be clearly viewed on the backlit LCD display. Integrated temperature sensor It allows variations in temperature to be detected. Detects wiring errors An integrated test function can be utilized to detect incorrect wiring and to automatically correct CT installation errors. Compliant with ANSI C12.20 and IEC 61557-12 IEC 61557-12 is a high-level standard for all PMDs (Performance Monitoring Devices) that are designed to measure and monitor electrical parameters in distribution networks. Compliance with IEC 61557-12 ensures a high level of equipment performance, in terms of metrology, as well as mechanical and environmental aspects (EMC, temperature, etc.).
