You do not need to "eject" the USB mass storage device before removing it.
Simply ensure that any file operation you've initiated is done, and remove
the USB drive from the oscilloscope's host port.
Do not connect USB devices that identify themselves as hardware type
"CD" because these devices are not compatible with the InfiniiVision
X-Series oscilloscopes.
If two USB mass storage devices are connected to the oscilloscope, the
first one is designated "\usb" and the second one is designated "\usb2".

To choose "expand about" center or ground
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.
To set the waveform expansion reference point:
1 Press [Utility] > Options > Preferences > Expand and select:
• 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.
