Setting guidelines

GlobalBaseSel : Selects the global base value group used by the function to define ( IBase ),
UBase ) and ( SBase ).
(
Operation : With the parameter Operation the function can be set On / Off .
Mode : The voltage and current used for the power measurement. The setting possibilities are
shown in table 21.
