User Manual
6.3.1 Menus
There are four menus visible at the top of the eosLink-FD window:
Menu 1 - File:
This menu provides the ability to collect both the measurement data file and the error log
file (both commands also have their own dedicated button) as well as a means of exiting the program.
Menu 2 - Connection:
The Connection menu has three options, including the ability to refresh the list
of available COM ports and choose a specific port number. If the program was launched prior to the
eosFD being connected, you will need to refresh the connection to allow the correct port to be chosen.
Menu 3 - Options:
This contains a number of secondary functions which are described below.
● The
Pump Options
window allows the user to change
the pump settings used to draw and analyze soil and
atmospheric cavity CO
2
gas concentrations. Altering
these values may affect the accuracy of measured flux
rates.
Purge Time
refers to the length of the purge
cycle between atmospheric and cavity samples.
Number of Samples
sets the number of concentration
measurements from which the median concentration is
taken.
Draw Time
controls how long to allow for
pump-transport of gas from a soil or atmospheric cavity
to the sensor for analysis.

The Pump Options window
● The
Device Settings
window allows the user to
change the eosFD’s operating mode, serial number
and stored calibration. Please contact Eosense for
access to these options if required.
Changing these
options may prevent the eosFD from collecting
flux measurements. Logging Mode
is the normal
operating mode for the eosFD, while
Calibration
Mode
allows for recalibration of the internal CO
2
sensor.
Reset Aux Flags
reverts any changes to the
internal diagnostic values, and
Factory Restore
reverts any changes made to the eosFD settings,
including calibration parameters and measurement
frequency settings.
