2) Accurate measuring of single/three phase active electric energy

3) Large-scale integrated circuit to lower power consumption

4) Anti-electromagnetic interference circuit improves anti-jam ability

5) Three-phase power supply and meter work normally if up to two

phases fail

6) No deviation occurs under normal delivery condition, no

calibration needed

7) Application: all meters adopt two-way electric measure circuits

and advanced SMT techniques through an advanced mechanism of digital

electric energy measurement,specified by IEC61036 technical

requirements
