Vertical Position (Vertical Position)
This is useful when you want to view the relationship between voltage and current waveforms, or when the
section of the waveform that you want to view does not fit into the display frame.
• You can select a value between 0.000 and ±130.000%.
• When the zoom factor is set to 1, a value of 100% corresponds to half the height (display range) of the
waveform display (which is three times the measurement range when the crest factor is set to CF3 and six
times the measurement range when the crest factor is set to CF6 or CF6A). The upper and lower vertical
display limits of the screen are 100% and –100%.

• As shown in the figure below, when the zoom factor is set to a value other than 1, the upper and lower display
limits of the screen do not correspond to three times the measurement range (or to ±100%) when the crest
factor is set to CF3 and six times the measurement range (or to ±100%) when the crest factor is set to CF6
or CF6A. You must take the zoom factor into account when setting a waveform’s position. In the figure below,
the crest factor is set to CF3, the voltage range is 100 V, the zoom factor is 2, and the vertical position has
been shifted by –25%. The waveform is shifted by the same amount that it would be if the zoom factor were
set to 1 and the vertical position was shifted by –50%.

When you want to zoom in on part of a waveform, we recommend that you take the steps below.
1. Set the zoom factor to 1.
2. Following the instructions in this section for shifting a waveform’s vertical position, shift the part of the
waveform that you want to view to the center of the display.
3. Set the vertical zoom factor.
