The Real-Time Clocks of the 71M65XX Metering ICs
要約:All Teridian single-/polyphase energy-meter system-on-chips (SoCs) support time-of-use metering. The devices have real-time clocks (RTCs) that adjust to better than 5ppm, which provides excellent timekeeping capabilities. This application note describes the features of the Teridian electricity-meter ICs relating to their RTCs. The article also recommends sequencing production processes of meters containing batteries.
