This screen (Fig. 145) contemporarily shows the saved instant values of the waveforms of
voltages V1, V2, V3, Vn scaled according to the Full scale (Fs) and the relevant RMS
values; these values have been saved by the instrument upon pressing the SAVE key.

The following keys are active on this page:
 The up (ZOOM+) or down (ZOOM-) arrow keys zoom in or out the displayed
waveforms.
 The
F1 key (or the PAG item on the display) advances to the following page of
saved current values.
 The
ESC key (or the smart icon on the display) to exit the function and go back
to the “Recording analysis” page (Fig. 143).
