Acquisition
Click the Acquisition tab of the Preferences dialog to access Acquisition
settings. This allows you to make more fine-grained adjustments to how
the instrument performs acquisition than is available using the pre-set
selections on the Preferences dialog.
You can view a summary of your Acquisition (and other) settings by
accessing Status dialogs from the menu bar:

Vertical → Channels Status

Timebase → Acquisition Status

Trigger → Acquisition Status

Math → Math Status, Zoom Status, or Memory Status
Offset Setting constant in - allows you to specify how Vertical scale
changes are displayed. Choose either:

Div(isions) - As gain changes, keep the vertical offset level
indicator stationary. With this selection, the waveform remains
on the grid as you increase the gain.

Absolute Volts - Have the vertical offset level indicator move with
the actual voltage level. With this selection, the waveform could
move off the grid.
NOTE: Regardless of whether you select Volts or Div, the Offset shown
in the Channel Setup dialog always indicates volts. However, when Div is
selected for the Offset Control, the offset in volts is scaled proportional
to the change in gain, thereby keeping the division on the grid constant.
