In addition to the skin mapping that John_F mentioned, there are also
post installation "storm simulators" that are used to make sure the unit
is working. Keep in mind that a stormscope, for all practical purposes,
is a fancy noise detector, so any electrical noise in your airplane is a
potential problem. You need to take care to avoid ground loops. If I
remember right (from the installation of my WX900), they want you to run a
discrete ground wire directly to the battery, and keep the unit isolated
from any other ground.
