The main functions and features :
1. Energy measurement ways: total single-phase power meritorious =positive meritorious + reverse meritorious.
2. Right through infrared interface programming meter settings and copied sheet data to support meter reading with shrinking table, table factory default is bar code numbers.
3. After the blackout enter low-power work, in the blackout shows that the current state of total consumption, continuous 24-hour blackout revealed about the closure.
4. Meter procedural device to prevent the failure caused flight function, and after the failure to stop measurement.
