Grounding
WARNING
The oscilloscope's ground connection through the USB cable is for
measurement purposes only. The oscilloscope does not have a protective
safety ground.
WARNING
Never connect the ground input (chassis) to any electrical power source. To
prevent personal injury or death, use a voltmeter to check that there is no
significant AC or DC voltage between the oscilloscope ground and the point to
which you intend to connect it.
CAUTION
Applying a voltage to the ground input is likely to cause permanent damage
to the oscilloscope, the attached computer, and other equipment.
CAUTION
To prevent measurement errors caused by poor grounding, always use the
high-quality USB cable supplied with the oscilloscope.
