Check system for the disturbance
Verify that the system does not respond to an external disturbance. You can shake the fence, pretending
if it is the wind, finally, like a tree branch. Because for this example, the level of disturbance is 769 mkV, so
the P
enetration threshold
(4400 mkV for low frequency LF) – is enough to avoid a false alarm.
