2.1.4 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.
