User Manual
While the eosFD is water resistant, avoid situating the probe in areas
of standing water or hollows where flooding is a possibility. For best
results choose a flat, clear soil surface that is free of large rocks to
insert the chamber. Where stability is a concern, use pegs and line to
secure the eosFD to the soil surface via the attached Mounting Ring,
ensuring that the guy-lines remain taut when the pegs are driven into
the soil.
Connect the eosFD to the 12-pin end of the SSC Power and Data
cable. Connect the DC+ Power Cable to the 2-pin end of the SSC
Power and Data Cable then to a 12 VDC power supply. Once
powered, the eosFD will pulse the pump 2-3 times, which indicates
that it is properly connected.

5.2 Maintenance
The eosFD should be checked-over monthly for best results. Check
the power supply and connection, ensuring that the eosFD pump
sounds when power is cycled. In the event of fouling, the eosFD
membrane can be cleaned by first gently removing any particles
using a dry, non-abrasive cloth. Then, use a damp (no solvents)
cloth to gently remove any remaining dirt or substance.
If the membrane appears to be significantly clogged or punctured
in any way, contact Eosense immediately to determine if the
membrane needs to be replaced. A damaged or fouled membrane
can lead to inaccurate flux measurements by the device. Make
sure to remove any vegetation growing in the collar or directly
around the eosFD that may block the side membrane. Finally,
ensure the collar is still flush with the surface, re-adjusting if
necessary.
