Precision Power Analyzer WT3000
* LabVIEW is a registered trademark of National
Instruments Corporation.
Note) This software cannot communicate with the WT using a serial (RS-232) interface (/C2)
or USB port (PC) (/C12).
The flicker measurement of three phase equipment, it requires adding frequency
measurement option (/FQ).
Utility Software
• Harmonic Measurement (/G6 option)
The Harmonic Analysis Software (Model 761922) loads data measured by the
WT3000 and performs harmonic analysis that complies with IEC61000-3-2 A2 of the
edition 3.0. You can use the model 761922 harmonic measurement software to
perform harmonic measurement tests conforming to IEC 61000-4-7 edition 2 (window
width is 10 cycles of 50 Hz and 12 cycles of 60 Hz) with WT3000.
Communications: GP-IB, Ethernet (/C7)
Harmonic Current Measurement Value List and Bar Graph
Enables PASS/FAIL evaluations of harmonic measurement results in line with
standard class divisions (A, B, C, D). Displays lists of measurement values, as well
as bar graphs that let you compare the measured value and standard limit value for
each harmonic component.
Measurement Mode
Three modes are available for harmonic
measurement.
• Harmonic observation: Lets you view
current, voltage, and phase angle for
each order in a bar graph.
• Waveform observation: Lets you view
measured signals to confirm the
suitability of the range and other factors.
• Harmonic measurement (standards
testing): For conducting standards tests
and making the associated judgments.
Efficiency is gained by performing tests
after checking the waveform in
Observation mode.
Harmonic Measurement / Voltage Fluctuation and Flicker Measurement Software (761922)
WTViewer is an application software tool that reads numeric, waveform, and
harmonic data measured with the WT3000 Precision Power Analyzer.
Communications:GP-IB, Serial (RS-232, /C2), USB(/C12), or Ethernet (/C7)
WTViewer 760122 WTFileReader (Combined into the WTViewer)
You can download this software program from our
web site
LabVIEW driver (Free)
• Flicker Measurement (/FL option)
This function enables voltage fluctuation
and flicker measurements in compliance
with IEC61600-3-3 Ed2.0 (2008).
* The flicker test can also be performed with the
WT3000 alone. Using the model 761922
harmonic/flicker measurement software (sold
separately), you can display trend graphs, CPF
graphs, or reports of the dc, dmax, and IFS
(instantaneous flicker sensation) values in
addition to the WT3000 judgment results.
• Numeric Data
WTViewer can simultaneously display
voltage, current, power and various
other measured parameters for one to
four elements individually, and for
∑ A
and ∑ B calculations.
• Measuring Harmonics*
WTViewer can numerically or graphically
display the results of measured
harmonics up to the 100th order for such
parameters as voltage, current, power
and phase angle.
* requires / G6 option
• Waveform
Voltage and current waveforms can be
monitored on the PC screen. You can
confirm the voltage-current phase
difference, waveform distortion, and
other phenomena.
• Viewing Trends
You can capture and view various data,
measured with the WT3000 on your PC
in a graphical trend format. This feature
lets you monitor power supply voltage
fluctuations, changes in current
consumption and other time-based
variations.
WT3000 File Reader (off-line)
WTFileReader software can load and display data measured by the WT3000
Precision Power Analyzer that has been saved to a memory medium. That data can
also be saved in CSV format.
