    3. Function Description

       3.1 Metering Function

    Active & reactive energy

    CT and VT ratio are resettable:CT1~1000:1 VT1~1000:1 Max.CT*VT1000

    Factory Default: CT ratio 1:1, VT ratio 1:1

    To set parameters through button,including code,CT, VT,meter address,CT.VT protection and remotely output control.(to set through communication is optional).

     

     

    3.2 Communication Function

    RS485 Communication (protocol Modbus-RTU)

     

    3.3 Display Function

    3.4 Backlight indication

    When the button is locked via communication, the backlight color will become purple;

    When backlight color is blue, it indicates built-in small relay disconnects; When backlight color is red, it indicates built-in small relay connects.
