Defeating the ground connection and "floating" the oscilloscope chassis will probably
result in inaccurate measurements and may also cause equipment damage. The probe
ground lead is connected to the oscilloscope chassis and the ground wire in the power
cord. If you need to measure between two live points, use a differential probe with
sufficient dynamic range.
Do not negate the protective action of the ground connection to the oscilloscope. The
WA R N I N G
oscilloscope must remain grounded through its power cord. Defeating the ground
creates an electric shock hazard.

Input a Waveform

The first signal to input to the oscilloscope is the Demo 2, Probe Comp
signal. This signal is used for compensating probes.
