Function and Features

1. Measure Function
1.1 Can measure positive and reverse active energy consume.
1.2 Can judge following data if it is with correct working: Battery, Comunication, clock, energy directions etc.
1.3 The energy is seperately stored by differenct tariff
1.4 Reverse active energy consume measuring, except to measure it as positive direction, also record total time of reverse, total energy consume, and each time period of energy consume, and the last time reverse energy start and over time, and store data.
1.5 Can store 12months frozen data.
1.6 When power cut, all data will not lose, and store more than 10 years
1.7 Can initialization of total energy and each time period of energy.
2 Clock and time period, tariff function
3 Calibration time function
4 Displaying function
4.1 Can display 5 integral + 1 decimal
4.2 Displaying required data circulate, circulate period can be set from 2~30s,the default value is 10s
5 Communication function
6 Output function
7 Program function
8 Copy meter function
