Overdraft can be permitted once under emergency condition, the over draft amount=Load Gate*24 Hours
· When meter trip at overload or after energy is exhausted, signal will be output for external

Warning facilities to remind customer of purchasing power or reducing load used.
· Load control can be selected
(1) Delaying trip at overload automatically and delay time can be selected freely
(2) No trip at overload but measuring overload energy separately

Maximum Demand Clear:
Max Demand can be cleaned by use of Data Collected Card.

Overdraft Function:
The selection to the energy overdraft function can be processed according to the requirement of user to realize the overdraft function once when residual energy is less than the warning gate. If no selection, the meter will take as no overdraft.

Pre-warning Output Function By Means of Trip:
To make the meter's warning function more effective in reminding user, this meter add an output return circuit with no battery contacts (AC 220V*5A/DC 12V*12A)to realize the output of 
(1) warning at overload and
(2) pre-warning at deficit energy
