5.2.5. SCOPE waveforms screens
Starting from a any page of numerical values it’s possible to select waveforms screens of
the input signals by pressing F2 key (or touch SCOPE at display). By pressing cyclically
F1 key the below screens are shown by meter:
 Simultaneous waveforms of voltages V1, V2, V3 and neutral voltage Vn (for three
phase 4-wire system and single phase), with their TRMS values as shown in below
screens:
