Avoid Overdriving the Vertical Input Amplifiers
N O T E
When the oscilloscope is running, the input waveform can overdrive the vertical input
amplifiers if you expand the vertical excessively. The result is distortion of the waveform.
Ensure that you select a region that will keep all of the waveform on the screen vertically.

Click and hold the left mouse button or touch screen stylus in a blank
space within the waveform display area, then drag the pointer to draw
a rectangle around the areas of interest on the waveform(s), then
release.
Click the Waveform Zoom menu item.
How the zoom takes place depends on whether acquisition is running
or stopped. If running, the oscilloscope adjusts vertical scale, vertical
offset, horizontal scale, and horizontal position as necessary to best
rescale the area you defined in step 1. If stopped, the oscilloscope does
a software magnification of the waveform.
In either case, a small dialog box appears in the corner of the screen,
with an "Undo" button; by clicking this button, you will undo the zoom
and return the oscilloscope to its previous settings.
