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.

The Snapshot All measurement type displays a popup containing a snapshot of all 
the single waveform measurements.
Charge Charge (in Amp-hours) is the measured area under 
the waveform. See “Area" on page 266.
