    Measurement
    		kWh&kVarhTotal active kWh (bidirectional --positive and negative in total)
    Electrical ParatmetersU (Voltage), I (Current), P (Active Power), Q (Reactive Power),S (Apparent Power), PF (Power Factor), F (Frequency)
    Function Mode
    		Prepaid ModeMeter will shut down the power once the credit balance is below zero. (Data like credit balance is saved in the meter)
    Postpaid ModeMeter won't shut down the power once credit balance is below zero. (Can remotely control the meter to shut down the power by using Prepaid System)
    Mode ChangeMeter can change the mode between prepaid and postpaid by receiving the command from prepaid system
    Control
    		Auto-tripping Control  Auto-tripping control is processed by the built-in high-capacity holding relay of the meters to realized on-off control of circuits breaker, also, this type of control will only be triggerred when meter is in Prepaid Mode
    Remote ControlRemote control will be command by prepaid system. When users give a command of switch on-off to a certain meter, this command will be send to meters through wireless communication and finally meter will shut down or recover the power after receiving the command. This type of control can be done when meter is in Postpaid Mode
