6.1.2. THE L1 PHASE VOLTAGE HARMONICS DISPLAY SCREEN
This information concerns the har-
monic pointed to by the cursor.
V-h03: harmonic number.
%: level of harmonics with the fun-
damental 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

key is
pressed.
THD: total harmonic distortion.
Vd: RMS distortion voltage.
The horizontal axis indicates the
orders of the harmonics. The level of
the harmonic is given as a percent-
age 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.
Harmonic selection cursor. Use the  or  key
to move the cursor.
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 .
Figure 53: example of display of harmonics of L1 phase-to-neutral 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 the harmonics of the current.
6.2.1. THE 3L CURRENT HARMONICS DISPLAY SCREEN
This information concerns the har-
monic pointed to by the cursor.
A-h05: harmonic number.
%: level of harmonics with the fun-
damental 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).
The horizontal axis indicates the
orders of the harmonics. The level of
the harmonic is given as a percent-
age with respect to the fundamental
or to the total RMS value.
Rang DC: DC component.
1 to 25: harmonics of order 1 to 25.
When the cursor exceeds order 25,
order 26 to 50 appears.
Harmonic selection cursor. Use the
 or  key to move the cursor.
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 .
Indicator of the presence of non-zero
harmonics of order higher than 25.
