650 and 800 nm, observing the SIF signal within the O A and O B oxygen absorption bands. To perform these measurements, the FluoreSENS 10 uses a fiber optic cable, motor, and data logger. NOTE: A second Flame spectrometer for measuring vegetation indices that covers the range from 350 to 1000 nm can also be added. -
Page 7: Hazards
Do not modify or attempt to repair the FluoreSENS 10 unit without consulting Campbell Scientific. 2.1 Hazards 2.1.1 Electrical hazards DANGER: To prevent electrical shock or potential danger, turn off the main power supply before connecting or replacing the battery. Failure to adhere to this imperative precautionary measure may result in serious injury or even loss of life. -
Page 8: Initial Inspection
The use of desiccants is recommended to prevent or eliminate the condensate. 3. Initial inspection Upon receipt of the FluoreSENS 10, inspect the packaging and contents for damage. File damage claims with the shipping company. Immediately check package contents against shipping documentation. Contact Campbell Scientific about any discrepancies. -

FluoreSENS 10 operations: (a) radiometric calibration, (b) manual dark sampling and (c) Real time monitoring of SIF signal The FluoreSENS 10 RTMC panel displays useful data from the data logger. For example, the data loggers built-in web pages, which display data logger health and program statistics, such as panel temperature, battery voltage, and program run-time errors, can be accessed through RTMC. - Page 25 6. The system will measure 50 samples. The integration time for each sample is automatically determined by the program based on the intensity of light. Once calibration is complete, prepare for manual dark measurement. Next, manual dark sampling is performed. FluoreSENS 10...

The data logger internal CPU can only store a small amount of data, so a microSD flash card is recommended with the CR1000X. In some situations, it may also be possible to remotely transmit time series data. For additional information on these options, please contact Campbell Scientific. FluoreSENS 10... -
Page 29: Post Processing
WARNING: Campbell Scientific recommends and supports only the use of microSD cards obtained from Campbell Scientific. These cards are industrial grade and have passed Campbell Scientific hardware quality testing. Use of consumer grade cards substantially increases the risk of data loss. - Page 30 (an .lmp file is provided by the manufacturer, or the coefficients can be found in the lamp calibration data sheet).
