When the instrument is supplied, these pages are not enabled, see

analysis of the harmonics. After pressing the
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
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.
The pointer
shows which
harmonic is
being measured
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.

SIMPLE ANALYSIS:
Line phase being measured
(L1-L2-L3) and relevant
voltage or current value
Total harmonic distortion and
relevant value in percentage
DETAILED ANALYSIS:
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.
