Why Doesn't the WT3000 Display the Phase Difference φU1-U2 of Voltage Between Phases?

Please verify the following settings on the WT3000:
  • Wiring System set to 3P3W or 3V3A
  • ITEM set to φUi-Uj 
    Element set to ΣA
  • ITEM set to φUi-Uk
    Wiring 3P4W or 3P3W(3V3A)
    Assign element 1,2, 3 to ΣA
  • Update rate is not too fast (<250ms)
