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.

The main functions and features :
Meter circuit design and selection of the components are according as the tolerance of greater choice of environment, so we can guarantee long-term stability of a piece of work. Basically error will not affected by the frequency, temperature, high harmonics, and the installation of location is arbitrary. After sealing unit manufactured without adjustment, greatly reduced the power sectorf+s workload of testing and calibration, meter - button box with pulse interface light coupler facilitate error testing. Detection the constant of pulse output / kw.H to find weather it is the same as constant table marked on nameplate meter, meter also provides low-frequency pulse acquisition (opts). When the one phase of three-phase three-line network is broken, three-phase four-wire network with a two-phase power outages, the watt-hour meter still normal, and display the lost pressure. Power meter in the factory before carefully debugging and test the installation of qualified lead seals. Energy applies to an ambient temperature of -25 fp c to 70 fp c and relative humidity over 85% of the region.
