Press F3 key to back to graphical screens and F2 key to change voltages’ or currents’
screens. Press F4 key or the up and down arrows (or touch the “HARM PAG” at display)
to show the screens relative to other harmonics orders up to 49
st
.
 Harmonics values of single V1, V2, V3 voltages and neutral voltage Vn and single
currents I1, I2, I3 and neutral current In (for three phase 4-wire system) with THD%
values both with histogram graphics and with numerical values in percentage or
absolute value depending on the desired settings. These values are shown in four
pages selectable by pressing cyclically the F1 key (or touch the “PAGE” at display). As
an example, the situation relative to L1 phase for voltage and current on 4-wire
systems is shown in the next pictures:
