7.3.3 Alarm or Lightning Warning
The Alarm or Lightning Warning state indicates any of the following:
l
The one-minute running average of the electric field is greater than |±2000 V/m|.
l
The SG000 shows close (0 to 5 mi) or near (0 to 10 mi) strikes.
At the Alarm state, display software shows E_FIELDALARM or LIGHTNINGSTRIKEALARM.
The red light flashes on RA100 remote alarms, and the siren sounds for 3 seconds every 2
minutes if within the start and stop times.
7.4 Lightning warning logic
The EFM measures electric field (efield) from -25,000 to +25,000 V/m. The EFM one-second
measurement of the electric field allows it to detect both cloud-to-ground and cloud-to-cloud
lightning strikes within a 25-mile radius. Lightning strike detection efficiency is 95% when within 5
miles, 93% when within 10 miles, and 68% when within 20 miles. The optional SG000 measures
lightning strikes and their approximate distance broken down into close (0 to 5 miles), near (0 to
10 miles), or distant (0 to 20 miles). The optional RA100 strobe provides lights that indicate the
lightning danger (Table 7-1 (p. 19)).
