6.2.2. THE L1 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 (for the C.A 8333 only) the
total RMS value as reference (%r).
A: RMS current of the harmonic in
question.
+178°: 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.
Ad: RMS distortion current.
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 (for the C.A 8333 only) 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, or (for the C.A 8333 only) of the
expert mode (three-phase connec-
tion only - see §6.5). To select the
display press  or .

Notes: Filters L2 and L3 display the current harmonics of phases 2 and 3, respectively. The screen is identical to the one dis-
played for filter L1.
6.3. APPARENT POWER
The S sub-menu displays the harmonics of the apparent power, for all connections except 3-wire three-phase.
The horizontal axis indicates the orders of the harmonics. The bars of the bar chart above the horizontal centreline signify harmonic
power consumed, those below it harmonic power generated.
6.3.1. THE 3L APPARENT POWER HARMONICS DISPLAY SCREEN
This information concerns the har-
monic pointed to by the cursor.
S-h03: harmonic number.
%: level of harmonics with the funda-
mental apparent power as reference
(%f) or (for the C.A 8333 only) the to-
tal apparent power as reference (%r).
+006°: phase shift of the voltage
harmonic with respect to the current
harmonic for the order in question.
: Indicator of energy generated
for this harmonic.
: Indicator of energy consumed
for this harmonic.
The horizontal axis indicates the
orders of the harmonics. The level of
the harmonic is given as a percent-
age of the fundamental apparent
power or (for the C.A 8333 only) the
total apparent power.
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 or L3. To select the display press
the  or .
