Software Enabling Measurement Complying with Harmonics Standard

Harmonic Current Measurement Value List
Displays harmonic measurement data as a single list.

Viewing Trends
You can capture various types of data measured into your PC at 200ms fixed intervals. Thus, you can view trends graphically. This feature lets you monitor power supply voltage fluctuations, changes in current consumption and other time-based variations.

Harmonic Current Measurement Value List
Displays harmonic measurement data as a single list.

Harmonic Current Bar Graph
Evaluates whether harmonic data is within the standard limit value, and displays the result as a bar graph. The display of evaluation results is color-coded, in colors such as red and blue.²

Waveform Observation
Lets you display voltage or current signal waveforms, and measure frequencies and peak values. Moving the cursor lets you display values for the displayed waveform.

2:Evaluations conforming to the IEC61000-3-2 Ed. 5.0

Automatic Report Generation
You can print harmonic measurement results as value lists and graphs, and save image data. Titles and comments can be entered in reports, letting you enter information such as measurement dates/times, device names or control numbers.

Entering Settings on the WT3000/WT3000E from Your PC

You can enter settings on the WT3000/WT3000E from your PC. The wiring method, filters, and scaling settings can be modified.

Converting Data to CSV Format

Waveform data and harmonic current values can be saved on the PC. Measured data can be saved to .csv files for easy access by spreadsheet programs such as EXCEL.

Voltage Fluctuation and Flicker Measurement

Voltage fluctuation and flicker measurement complying with IEC 61000-3-3 is executed. Calculates all the voltage fluctuation and flicker values of dc, dmax, d(t), Pst, and Plt, compares them to the preset limits, and indicates the total judgment.

Measured Value and Judgment for Each Observation Period

Normal Voltage Fluctuation and Flicker Measurement

The final values of dc, dmax, Tmax, and d(t) are compared with the respective limits, and the judgment (pass or fail) is displayed to the right of the final value. If a steady-state condition does not occur during the measurement period, it is considered to be a fluctuating condition. The measurement result of dc is displayed as Undef (undefined), and the judgment of dc is displayed as Error.
The short-term flicker value, Pst, is calculated, compared to the limit, and the judgment (pass or fail) is displayed.

Displaying the Trend Graph
You can show Trend Graph View. You can select from the following measurement functions.

dc	:	Relative steady-state voltage change
dmax	:	Maximum relative voltage change
Tmax, d(t)	:	Period during which relative voltage change exceeds the threshold level
idc	:	Instantaneous relative steady-state voltage change
idmax	:	Instantaneous maximum relative voltage change
id(t)	:	Period during which instantaneous relative voltage change exceeds the threshold level
PF	:	Instantaneous flicker sensation (IFS)

Displaying the CPF Graph
You can select the element and color to be displayed on the CPF graph.
Up to four elements can be displayed simultaneously.
You can set a separate color for each element.

Printing
You can create reports using the data measured with the software.
