3rd/5th/Current Wave
（
Limit Values
）
If you set Limit Values to “3rd/5th/Current Wave,” the tests using third and fifth harmonic currents
and current waveforms that are shown in section 7.4. 3, “Rated power

5 W and

25 W” of IEC
61000-3-2 Ed5.0 are performed. (It is only valid for single-phase, two-wire circuits.)
When you select “3rd/5th/Current Wave,” the phase angles of the points of the current
waveform are displayed on the V/I waveform screen. This is only valid when the view area is
set to 1-Screen.
The phase angles of the points of the current waveform are measured automatically. From the
cycle that includes the maximum absolute peak value within the window, the phase angles
are determined from the following references: the points that reached the current threshold
(which is 5 % of the absolute peak) and the points where the voltage crossed zero on the
rising and falling slopes.
Correct judgments cannot be made for half-wave rectification circuits.
Ipk(abs): Maximum absolute
peak value within the
window
0.05*Ipk: Current threshold
P1, P4: The phase angles of the
points where the curr-
ent reached the current
threshold with the
points where current
began flowing as the
references
P2, P5: Phase angles of the
positive and negative
peaks
P3, P6: The phase angles of the
points where the curr-
ent decreases to the
threshold
