The CS110 kit includes:
The CS110 uses a reciprocating shutter instead of the traditional rotating vane field mill. The reciprocating shutter is electrically connected to ground potential by a flexible stainless-steel strap. The strap operates below its fatigue limit, resulting in an ultra-reliable electrical ground connection to the shutter.
The reciprocating approach provides better low-frequency error performance than the traditional rotating vane field mill because it has a convenient zero-field (closed shutter) reference. The zero-field reference allows the CS110 to measure and then correct for electronic offset voltages, contact potentials, and leakage currents of each individual measurement (Patent Pending).
The CS110 also contains circuitry to measure and compensate for insulator leakage currents occurring on the charge amplifier input, eliminating measurement errors caused by fouled insulators. If insulator surfaces become conductive because of surface contamination, a leakage current compensation circuit applies an equal and opposite polarity current to the charge-amplifier input that prevents saturation of the electronics.
The CS110 has a one year warranty against defects in materials and workmanship. Campbell Scientific does not warrant that the CS110 will meet customer’s requirements or that its operation will be uninterrupted or error-free.
Atmospheric or local electric field conditions or different site characteristics may cause false information, late data, or otherwise incomplete or inaccurate data. The CS110 only measures conditions that make lightning more likely. Just as with weather forecasts, the CS110 measurements only help assess the probability of lightning. Lightning can occur causing personal injury, even death, or damage to property without any warning from the CS110.
Campbell Scientific is not liable for special, indirect, incidental, or consequential damages from the use, failure, or malfunction of the CS110. A full statement of the CS110’s Warranty is contained in the CS110 Manual.

Datalogger Considerations
The CS110-LGR can be interfaced to another datalogger via the Power/SDM cable if the application requires an additional datalogger.
The CR1000’s on-board programming language, CRBasic, provides data processing and analysis routines that support user control over sample (measurement) rates and setting of alarm conditions. LoggerNet Datalogger Support Software facilitates programming, communications, and data retrieval between the CS110 and a PC.
The CS110 has sealed connectors for attaching meteorological sensors and three digital control ports for controlling external devices and/or triggering alarms. The embedded CR1000 datalogger measures the sensors, processes the measurements, stores the data in tables, and can initiate communications.
Connector Label | Compatible Sensors (one sensor per connector) |
Temp/RH | HMP60-L, HC2S3-L (choose the -C cable termination option for these sensors) |
Wind | 05103-LC, 05106-LC |
Solar | CS100 barometer, CS106 barometer (barometers connect to the CS110 via the 17460 cable; barometers must be housed in a separate enclosure such as the ENC100) |
Rain | CS700-LC, TB4-LC, TE525-LC, TE525WS-LC, TE525MM-LC |
Communication options compatible with the embedded CR1000 include direct connect, Ethernet, phone modems (land-line and cellular), radios, short haul modems, GOES satellite transmitters, and multidrop modems.
The 17642 Zero Electric Field Cover (ordered separately) is used to check the electric field offset voltage of the CS110. If the measured electric field is ≥|60 V/m| with the Zero Electric Field Cover on, then inspection and cleaning of the electrode surfaces is recommended.
The SG000 (ordered separately) can be used in conjunction with our CS110 to create a complete lightning-threat measurement and analysis system. This system combines the advantages of two complementary lightning-warning technologies. The SG000 reports actual lightning strikes occurring at distances up to 20 miles—providing a comfortable warning time for incoming storms. The CS110 reports electric fields associated with local thunderstorm development—providing a warning prior to lightning strikes.
