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.

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.

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.

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.

Flicker Measurement Display

Displays data during measurement

in real-time. Display can also be

switched to D measurement and

"Pst" value.

*2. Decision function not included.

*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.
