The meter features a comprehensive LCD display showing current, previous month, and 12-month cumulative electricity consumption data across various rate periods.
Visual indicators include communication status, reverse power flow, rate period sets (① ②), battery/supercapacitor undervoltage, programming status, and password verification errors.
T1, T2, T3, T4 indicators show current rate status (tip, peak, flat, valley).
Clear ON/OFF indicators display the current relay state for load circuit control.
For optimal performance, install the meter indoors whenever possible. Outdoor installations require special instrument box protection. Mount the base plate on fire-resistant, vibration-free walls. Avoid locations with corrosive gases, excessive dust, or salt spray. Always follow the wiring diagram provided in the meter's tail cover and use copper wiring for terminal connections. Ensure terminal screws are properly tightened to prevent overheating and potential meter damage.
