When you change a channel's volts/division setting, the
waveform display can be set to expand (or compress) about the
signal ground level or the center of the display.
Expand About Ground The displayed waveform will expand
about the position of the channel's ground. This is the default
setting. The ground level of the signal is identified by the
position of the ground level ( ) icon at the far-left side of the
display. The ground level will not move when you adjust the
vertical sensitivity (volts/division) control.
If the ground level is off screen, the waveform will expand about
the top or bottom edge of the screen based on where the ground
is off screen.
Expand About Center The displayed waveform will expand
about the center of the display.
