To Measure Battery-Powered Devices

N2820/1A User's Guide
When making measurements on a battery-powered (floating)
device, such as a mobile phone, always connect the supplied
ground lead between ground on your device and the probe's
ground connector as shown in
the ground lead onto the probe's connector. Without the ground
connection, the common mode voltage is not guaranteed to be
within the common mode range of the amplifiers.
Failure to connect the ground lead may result in inaccurate waveforms.
