■ Applications of 3193
Support up to Harmonic / Flicker analysis when using the optional 9605 HARMONIC / FLICKER MEASUREMENTS UNIT
.
Graph Display of Harmonics
Voltage, current and power
can be analyzed and displayed
by bargraphs of harmonic
amplitude, content and phase
angle.Voltage, current and power
can be displayed simultaneously
for a single channel, or a single
parameter can be displayed
simultaneously for each of three
channels.
List Display of Harmonics
The harmonic list display
shows the amplitude, pro-
portion, phase angle and
distortion for each harmonic
of voltage, current and power.
Displaying only proportion,
or two parameters simul-
taneously, such as amplitude
and phase angle, is selectable.
Vector Display of Harmonics
The harmonic vector display
shows the voltage, current and
phase angle for each harmonic,
making clear the voltage-
current phase relationship.
Waveform Display
The waveform display shows
one cycle of the voltage and
current waveforms. RMS and
peak values can be displayed
along with voltage and current
waveforms, or voltage and
current waveforms for up to
three channels can be displayed
at the same time.
Flicker Measurement Display
Displays data during measurement
in real-time. Display can also be
switched to D measurement and
"Pst" value.
Monitor Display
The relative "d" voltage change
∆V/V and the instantaneous
flicker value "S(t)" can be
displayed in a time series,
so past variations are clearly
displayed.

*3. The reading accuracy of the input unit must combined with the analysis accuracy shown above. When
used with a clamp sensor, accuracy and frequency characteristics of the clamp must be added to the
analysis accuracy above.
*1. The 9605 does not support limit values, so pass/fail decisions based on limit values, classification
of special waveforms (A to D) and 2.5-minute measurement function for measuring transient harmonic
currents are not supported.
