Function
1. kWh indicator:the variational frequency means the electricity consumption, 1600imp/kWh
2.Alarm indicator:when the electricity consumption reaches to the seted kWh value, the red indicator will flash and the backlight lights and remind the user to buy electricity.
3.backlight display:insert card or the alarm value cause the backlight on.
4.LCD display:
(1)Total kWh
(2)Remain kWh
(3)Relay OFF indication:when the left kWh is 0, relay will turn off and LCD indicate the sign.
(4)Relay On indication:when user buy electricity again, the relay will turn on and LCD indicate the sign.
