for this procedure. Using your finger provides insufficient accuracy. The
calibration has a ten-second timeout in case no cross is touched.
Avoid parallax errors by placing your line of sight directly in front of each
cross before touching.
Preferences
Audible Feedback
You can elect to have audible confirmation each time you touch a screen or
front panel control.

Touch Utilities  Preferences from the menu bar.

Touch the Audible Feedback Enable checkbox so the oscilloscope emits
a beep with each touch of the screen or front panel control.
Auto-calibration
You can choose to have your instrument automatically recalibrate itself
whenever there is a significant change in ambient temperature. If you do
not enable this option, the oscilloscope only recalibrates at startup and
whenever you make a change to certain operating conditions.

Touch Utilities  Preferences from the menu bar.

Touch the Automatic Calibration Enable checkbox.
Offset Control
As you change the gain, this control allows you to either keep the vertical
offset level indicator stationary (when Div is selected) or to have it move
with the actual voltage level (when Volts is selected). The advantage of
selecting Div is that the waveform remains on the grid as you increase the
gain. When Volts is selected, 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.

Touch Utilities  Preferences from the menu bar.

Touch the Offset/Delay tab.

Under Offset Setting constant in: touch either the Div or Volts button.
