Data File
Used to create new data files. If no file has been selected, you will be prompted when the first records are
taken. Click on
Data File
to create a new data file and enter a name in the File name box (.csc extension

New Measurement
Only available once records have been saved. Allows the specification of a new data file (as well as the
other options).
Graphing Options
Allows setting up the graph min-max Y-axis scales. Click on the Graphing Options button to set the
Minimum and Maximum Y-axis values for reference CO
2
(Cr), Delta CO
2
(dC) and soil respiration rate
(Sr). CO
2
, Delta CO
2
and soil respiration rate are plotted simultaneously.
