6.1.2. L1 PHASE VOLTAGE HARMONICS DISPLAY SCREEN
Information about the harmonic at
the cursor position.
V-h03: harmonic number.
%: level of harmonics with the
fundamental RMS value as
reference (%f) or the (total) RMS
value as reference (%r).
V: RMS voltage of the harmonic
in question.
-143°: phase shift with respect to
the fundamental (order 1).
max – min: maximum and
minimum levels of the harmonic
in question. They are reset
when the harmonic number is
changed or the button is
THD: total harmonic distortion.
Vd: RMS distortion voltage.
NOTES: Filters L2 and L3 display the harmonics of the phase-to-neutral voltage for phases 2 and 3, respectively. The
screen is identical to the one displayed for filter L1.
There is no phase shift or distortion value for the neutral channel.
6.2. CURRENT
The A sub-menu displays harmonics of the current.
6.2.1. 3L CURRENT HARMONICS DISPLAY SCREEN
Information about the harmonic
at the cursor position.
A-h05: harmonic number.
%: level of harmonics with the
fundamental RMS value as
reference (%f) or the (total) RMS
value as reference (%r).
A: RMS current of the harmonic
in question.
+179°: phase shift with respect to
the fundamental (order 1).

Display of the 3 phases 3L, of L1, L2,
L3, N, or of the expert mode (three-
phase connection only - see §6.5). To
select the display press or .
The horizontal axis indicates the
orders of the harmonics. The level of the
harmonic is given as a percentage with
respect to the fundamental or to the
total RMS value.
DC: DC component.
1 to 25: harmonics of order 1 to 25.
When the cursor exceeds order 25,
order 26 to 50 appears.
