OPEC Open-Path Eddy-Covariance System TIP NOTE • Set the file size (Bale size) in the "Time Settings" screen. For the time series files, use a one hour file size and for the online flux data, use a one day file size. Practice converting the data from the card and processing it with your off-line tools. Only through this type of experimentation will you determine the file sizes that work best for you. • Finally, change the output file name. The default output file name is TOB1_stationname.ts_data.dat, where stationname is the datalogger's station name and can be set using DevConfig.exe (part of LoggerNet). The factory default station name is the datalogger serial number. Right click on the stationname.ts_data file and select "Change Output File". If any other parameters are later changed, CardConvert will return to the default output file name. • Click on the "Start Conversion" to start the conversion process (FIGURE 4-9). FIGURE 4-9. Fully configured CardConvert start up screen The converted files will look something like the 20 Hz files shown in FIGURE 4-10. Each file name will consist of a user specified file name and the time stamp of the first record in each file with a one minute resolution. Note that the first file and last file in the folder are smaller than the rest. This is because they do not contain a complete hour of data. 20

Set the file size (Bale size) in the “Time Settings” screen.
For the
time series files, use a one hour file size and for the online flux data,
use a one day file size.
Practice converting the data from the card and processing it with
your off-line tools.
Only through this type of experimentation
will you determine the file sizes that work best for you.
TIP
•
Finally, change the output file name.
The default output file name is
TOB1_
stationname
.ts_data.dat, where
stationname
is the datalogger’s
station name and can be set using DevConfig.exe (part of LoggerNet).
The factory default station name is the datalogger serial number.
Right click on the
stationname
.ts_data file and select “Change Output
File”.
If any other parameters are later changed, CardConvert will
return to the default output file name.
NOTE
•
Click on the “Start Conversion” to start the conversion process
(FIGURE 4-9).
