The following keys are active on this page:
 The
F1 key (or the PAG item on the display) advances to the following page
of saved values relative to the voltage vector diagram.
 The
ESC key (or the smart icon on the display) to exit the function and go
back to the “Recording analysis” page (Fig. 181).
This screen (Fig. 207) displays, with graphic and numeric indications, the phase delays,
expressed in degrees [°], between voltage V1 and current I1, so that the inductive or
capacitive nature of the electrical installation may be found out. In detail:
 positive angle: inductive load
 negative angle: capacitive load

This screen (Fig. 208) displays, with graphic and numeric indications, the phase delays,
expressed in degrees [°], between voltage V1 and V2, V2 and V3, V3 and V1. Voltage
unbalance values are also displayed.
