| Forced Diffusion | |||||
| 2016-06-06 | FD20160001 | eosFD | Installed | Forced Diffusion | Installed at Twitchell Alfalfa. Powered from CR1000 power connector, but did not seem to be running. Could not find the software to check on it. |
| 2016-07-07 | FD20160001 | eosFD | Removed | Forced Diffusion | Removed from the Twitchell Alfalfa. It does not seem to be getting power even connected to a independent 12V battery. Brought in for testing. |
| 2016-07-15 | FD20160001 | eosFD | Installed | Forced Diffusion | Installed after testing in the lab. It seemed to work with no changes to the set up. |
| 2017-06-23 | FD20160001 | eosFD | Removed | Forced Diffusion | Removed from Twitchell Alfalfa and brought back to lab to send back to Eosense |
| 2017-09-06 | FD20160001 | eosFD | Installed | Forced Diffusion | Reinstalled with new 90 degree cable after factory refurb. |
| 2017-09-19 | FD20160001 | eosFD | Removed | Forced Diffusion | Removed from the field because it has not been collecting data and some of the data were 0. Brought back to the lab for troubleshooting. |
| 2017-09-21 | FD20160001 | eosFD | Installed | Forced Diffusion | Reinstalled at TA after testing in the lab. It is now on its own individual DC-DC converter to step down from 24V to 12V. |
| 2017-10-13 | FD20160001 | eosFD | Removed | Forced Diffusion | Removed from TA because it was giving bad readings (200? ppm +/- 200? ppm). |
| 2018-04-05 | FD20160001 | eosFD | Installed | Forced Diffusion | Installed at TA in the soil between the soilco2 datalogger enclosure and the solar panels. We tried to sync the sensor time to system time, but the change was not saved. |
| 2018-06-13 | FD20160001 | eosFD | Removed | Forced Diffusion | Removed with Twitchell Alfalfa site decommissioning. |
| 2014-08-13 | FDC-11-13-006 | FD Classic | Installed | Installed with the other soil co2 equipment at Twithell Alfalfa. | |
