When using the N2820A probe to make measurements on a
battery- powered (floating) device, always connect the supplied ground lead
between ground on your device and the probe's ground connector as
shown in the following figure. Simply snap the end of the ground lead
onto the probe's connector. Without the ground connection, the probe's
common- mode input amplifier cannot properly display waveforms.
