Main functions

◆  Able to measure the bi-directional energy, exactly the negative and positive energy, both to be accumulated at one direction, effectively avoid the tampering user and electric loser.

◆  LED used to display the user code, accumulated      the consumed KWH and rest KWH in turns (for prepaid type meter).

◆  It will record the KWH datum every 15 minutes, and save them in case of power failure.

◆  Able to clear the datum, and backup the data for check.

◆  Push key provided to set meter No, maxi power limit, able to forcedly switch off power supply, clear off the data (need to verify the password, and the password can be changed).
