THORGUARD LIGHTNING SYSTEM SPORTS COMPLEX
LHL: Lightning Hazard Level. A number from 1-9. 1 means a 10% chance of lightning and 9 which means 90% chance of lightning within the Sensor Range (normally 12-15 miles). An LHL greater than 4 indicates lightning is occurring or has the potential of occurring in your area.
DI: Dynamic Index. Number from 1.0 - 9.9 “1” means 10% chance and 9.9 means 99% chance of lightning within close proximity of your sensor location. A DI greater than zero means there is lightning in the area!
AD: Alarm Level. Any time you get a Red Alert, the AD will start at 10 which means you have at least 10 minutes until you could get an All Clear signal. The AD will reset itself to 10 until all static charge is out of the area and play can resume. The AD will count down when no “new” surges in energy have been detected.
FCC: Field Collapse Count. Basically, the FCC number gives you an idea of how many lightning strikes have occurred within the sensor range. It is helpful to watch the FCC count as the system goes from Caution-Warning-Red Alert as it allows you to see how “active” a storm is in terms of lightning strikes.
