Essential function

Keyboard:	input the credit TOKEN, various technical TOKEN and other various control commands through keyboard.
Indicative light of relay status:	green, means relay is under the condition of connection; red, relay is tripping; flash between red and green, relay connected and the remaining amount lower than alarm amount.
Buzzer:	the energy meter have the function of sound warning, the ringing time can be set.
Relay:	Energy meter at the normal condition (non-tamper condition), rechargeable amount minus overdraft amount is more than zero, then the relay closing.
Load control and protection:	when energy meter detected that the current total power more than ot the same as user's electrical load threshold, last to test time (default time is 1 minutes), energy meter will disconnect user load. When the load threshold is zero, this function has no effect.
