This screen (Fig. 132) contemporarily shows the instant values of the waveforms of voltage
V12 and current I1, scaled according to the relevant 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 F2 key (or the ZOOM V or ZOOM I item on the dislay) switches between voltage
zoom and current zoom (only if the manual zoom mode has been activated).
 The up (ZOOM+) or down (ZOOM-) arrow keys zoom in or out the displayed
waveforms (only if the manual zoom mode has been activated).
 The F1 key (or the PAG item on the display) advances to the following page of saved
values relative to phase 2 voltage and current.
 The ESC key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 124).
This screen (Fig. 133) contemporarily shows the instant values of the waveforms of voltage
V2 and current I2, scaled according to the relevant Full scale (Fs) and the relevant RMS
values; these values have been saved by the instrument upon pressing the SAVE key.
