Measurements on Battery Powered Devices
Measurements on Battery Powered Devices
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 Figure 4. Simply snap the end
of 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.
NOTE
Failure to connect the ground lead may result in inaccurate waveforms.
