afterwards 4) Scrolling display energy consuming information
which is convenient for user 5) Warning when residual energy
is deficient to remind users of purchasing energy in
time 6) Delay trip at overload automatically 7) IC card
adopting ISO standard IC card 8) Adopting large-scale special IC
with industrial class design and high accuracy 9) Special
large capacity meter reading card with high accuracy *0) One meter
with one IC card which adopts special security measures to
ensure the security and reliability of data *1) Special
Setting Card and Meter-replacing Card are convenient for
registration and maintenance of management department
*2) Adopting check and error correction measures in the
software to ensure the data's validity and reliability
*3) Reading back energy consuming data automatically through
IC card, convenient for management *4) Adopting power
failure treatment technique to ensure the data being kept for
*0 years
