Explanation
• Selecting the Target Element to Be Specified
Only the installed elements are displayed. The Element menu is displayed according
to the element configuration of the product.
• Zoom (Vertical Direction Only)
You can expand or reduce each displayed waveform (voltage/current). You can select
the zoom factor from the following:
0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8, 1, 1.14, 1.25, 1.33, 1.41, 1.5, 1.6, 1.77, 2, 2.28, 2.66,
2.83, 3.2, 3.54, 4, 5, 8, 10, 12.5, 16, 20, 25, 40, 50, and 100
• Moving the Position (Vertical Direction Only)
The displayed position of the waveform can be moved vertically to the desired position such
as when you wish to view the mutual relationship between the voltage and current waveforms
or when the section of the waveform you wish to view goes out of the display frame.
• The position can be set in the range from 0.000 to
±
130.000%.
• When the zoom factor is 1, half of the total vertical span of the waveform display
screen (equal to measurement range
×
3 or measurement range
×
6 when the
crest factor is set to 3 or 6, respectively) is considered to be 100%. The span
between the vertical center of the screen to the upper limit of the screen is 100%;
the span between the vertical center of the screen to the lower limit of the screen is –100%.

Note
To expand and view a section of the waveform, we recommend the following procedure.
1. Set the zoom factor to 1.
2. Move the vertical position so that the desired section of the waveform is at the center
position (according to the procedure described in this section).
3. Set the vertical zoom factor.
