    ▋ Work-site Installation

    Parameter Description&Value
    Measurement
    		 kWh&kVarh Total active kWh (bidirectional --positive and negative in total)
    Electrical Paratmeters U (Voltage), I (Current), P (Active Power), Q (Reactive Power),S (Apparent Power), PF (Power Factor), F (Frequency)
    Function Mode
    		 Prepaid Mode Meter will shut down the power once the credit balance is below zero. (Data like credit balance is saved in the meter)
    Postpaid Mode Meter 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 Change Meter 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 Control Remote 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
