The SG000 is an optical-coincidence lightning sensor that detects actual lightning strikes for up to 20 miles away. Available as an option for our CS110 Electric Field Meter, the SG000 Strike Guard is used in conjunction with the CS110 to create a complete lightning-threat measurement and analysis system. Data from the two sensors can be used to control warning systems and to help personnel make evacuation and shutdown decisions.Read More
The SG000 Strike Guard detects cloud and cloud-to-ground lightning within a 20-mile radius. Strike information is classified in three range categories as lightning detected within 5 miles, 10 miles, and 20 miles. To prevent false alarms, the SG000 requires an optical signal to coincide with a magnetic-field-change signal before reporting lightning.
The SG000 is typically mounted on the same tripod or pole as the CS110. The SG000 connects to the CS110 via the FC100, the 14291 Field Power Cable, and the FC100CBL1-L (typically 10+ feet), and the following equipment depending on which CS110 port it is connected to.
The SG000 has three categories for lightning detection range estimates:
The SG000 is an add-on option to the CS110. Due to a contractual agreement, it cannot be sold without the CS110, as a stand-alone sensor.

According to the manufacturer, "Lightning flashes in the Alarm category are most likely to have occurred within 5 miles of the Sensor. Lightning flashes in the Warning category are most likely to have occurred within 10 miles of the Sensor. Lightning flashes in the Caution category are most likely to have occurred within 20 miles of the Sensor."
The SG000 is not capable of determining the exact distance to a lightning strike. Determining the exact distance would require multiple sensors and a triangulation method using TOA (Time of Arrival).
The CS110 and the tower should be positioned away from each other a distance of three times the tower’s height.
If the radio signal is strong enough, the SG000 may pick it up as one of the two components the SG000 measures to detect lightning. If this signal coincides with a light flash from a windshield or headlight, it could generate a false strike signal. Also, constant bombardment of the SG000 by sufficiently strong RF signals will pull the sensor out of its quiescent state, affecting its current drain. This will eventually degrade the battery and shorten its expected four-year lifespan.
To simulate a lightning strike to the SG000, use a camera flash to flash the glass bulb from a distance of 5.08 to 7.62 cm (2 to 3 in.). Note: A flash from a cell phone usually isn't large enough to simulate a lightning strike.
To simulate high electric fields on the CS110, run a comb through your hair and hold it a distance of 2.54 to 5.98 cm (1 to 2 in.) from the shutter of the CS110. Other items such as plastic bags or balloons, or fur on glass, can be used as well.
