Can the ThunderBolt distinguish between real lightning/storm activity and false signals?
Yes. The ThunderBolt contains a special software routines for detecting and minimizing false triggering from non-storm sources. These routines trigger special warning messages if the level of this background noise is too high for normal storm detection and ranging. A background noise sampling routine can be run at any time from the main menu. It should be re-run any time the unit is moved or new equipment or electronics are placed nearby.
