The pointer
shows which
harmonic is
being measured
Page 00
Total harmonic distortion and
relevant value in percentage
Line phase being measured
(L1-L2-L3) and relevant
voltage or current value
Harmonic order (h1 to h50) of the
phase being measured (L1-L2-
L3) and relevant absolute current
or voltage value of the harmonic.
Harmonic order (from h1 to h50),
relevant conventional sign (– or +)
and value of the harmonic given in
percentage.
Phase angle between the voltage and current harmonic of the
same order: a phase angle between 0
°
and 90
°
and between
270
°
and 360
°
corresponds to a generated harmonic; an angle
between 90
°
and 180
°
and between 180
°
and 270
°
corre-
sponds to an imported harmonic.

Displaying of the harmonic analysis
When the instrument is supplied, these pages are not enabled, see
page 29 to enable them.The
key is active, access to the detailed
analysis of the harmonics. After pressing the key, a pointer
appears along the horizontal axis (see figures below). To display the
data relating to the single harmonics move along the histogram using
the (moves from left to right) and (moves from right to left)
keys. For each harmonic the instrument measures the % value with
reference to the fundamental and the single harmonic angle between
the "V" harmonic and the "A" harmonic of the same order.
