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.
