I.Function and Feature
1.Wide load range ; high accuracy , reliability and sensitivity; low power loss.
2. Bi-directional measuring, accurately measure the active energy of both forward and reverse power.
3.Passive pulse output interface with optocoupler isolation.
4. The meter uses LCD in a clearer display and nicer appearance.The total consumed energy is displayed in the top line, while the other items of constant,meter NO., voltage , current,power, power factor and frequency are displayed in the lower line in turns with an interval of 5 second .
