To retrieve data from the SD card, place the card in the memory card reader. Connect the reader to
your computer's USB port. Windows should recognize the reader as a USB Drive, which will appear in
File Explorer (Drive letter may vary):
Double-click on the DATA folder to view data files:
Notice the file name contains the date in YYYYMMDD format. Select the day you want to view and
double-click to open. Once the file is open you can insert a couple of rows at the top, and add column
headings into the new file. Save the file to your computer rather than to the card, since you have
altered it by adding the header.
To avoid completely filling the memory card (which would cause logging to stop), periodically copy all
the files you want to keep to your computer, then delete the original files from the card.

Data Analysis
In order to make sense of the data when it has been uploaded to a spreadsheet, first make a record of
the parameters and units that the sensor is reporting. This information can be found in the sensor
manual, where the default settings are listed. If the sensor has been re-programmed since leaving
NovaLynx, these parameters may have been changed, and it may be necessary to retrieve the settings
from the sensor itself.
Create a spreadsheet with the appropriate column headings and save it. Each time a log file is
imported to a spreadsheet, insert some blank rows at the top of the sheet, then copy the headings
from your saved headings file and paste it into the spreadsheet containing your data. Save the
modified file to your computer for analysis.
