The UL(voltage wiring mode) parameter should be set as 0, the IL(current wiring mode) parameter should be set as 0 at the parameter setting interface. B Three-Phase Three-Line open Delta Mode (2LL, 2CT) Open delta wiring mode is often used in high voltage systems.
- Page 7 User Manual A Power Supply The power supply for this meter is AC 85-265V (45-55Hz) or DC 85-300V. Terminals for the power supply are (L/+,N/-). The typical power supply wiring is as followed: If the quality of power is poor or there is an EMI problem, it’s recommended to equip an EMC filter in the auxiliary power supply loop.

User Manual The terminal PE1-/PE1+ are used for active energy pulse output. The terminal PE2-/PE2+ are used for reactive energy pulse output. DI (Digital Input) It is used for measuring real state (connected, disconnected) of external switch, and make a resolution of the 2ms SOE event record. - Page 9 User Manual 3) Press button “P”, it will display the values of power parameters circularly.
- Page 10 User Manual 4) Press button “H”, it will display the total harmonic distortion(THD) of voltage or current circularly. Press “H” or“E” , the meter will display the 2nd~31th HC(harmonic content). The harmonic order will increase from 2nd to 31st by one each time P is pressed. And the harmonic order will decrease by one each time E is pressed.
