When the Graph Window is Bar
• Display Item (Display Item)
The following parameters can be displayed.
RMS (rms value), P (active power), hdf (percentage content), φ (phase)
• Maximum Order to Display (Display Max Order)
Set the harmonics to display in the graph window.
The range is as follows.
Line RMS mode: 1 to 40
Power mode: 1 to 35
• Vertical Scale (V Scale)
Set the vertical scale to Linear or Log (logarithmic).
This setting applies to the scales for RMS (rms value) and P (active power).
Graph display example
1st harmonic Up to the 40th harmonic
When the Graph Window is Vector
• Numeric Display On/Off
Set whether to display the numeric measured results in the graph window.
ON: The numeric measured results are displayed.
OFF: The numeric measured results are not displayed.
• Zoom (U:Zoom, I:Zoom)
You can change the size of vectors. When you zoom the vectors, the value that indicates the size of the
vector display’s peripheral circle changes according to the zoom factor.
Range: 0.1 to 100
When the wiring system is 3V3A (three-voltage three-current method),
3P3W→3V3A (conversion of three-phase three-wire system to
the three-voltage three-current measurement method), or
3P4W→3V3A (star-delta transformation)
• U1(1), U2(1), and U3(1) are line voltages.
• I1(1), I2(1), and I3(1) are line currents.
