Pressing ESC key (or smart icon at display) to exit from each screen and back to the
previous one.
CAUTION
 The vectors of voltages are referred to the external circle on each diagram
and the vectors of current are referred to second circle. The vectors’ sizes
are designed so that the vector of maximum amplitude can touch the circle
and the other vectors are scaled with respect to it proportionally to their
amplitude.
 The rotation positive reference associated at each vectorial diagram is
clockwise.
