7. In the File name text box enter the name of the file in which to save the data. The extension
.ctd is added automatically.
NOTE.
Windows 7® will not save any data files to the folder selected in the dialog box.
Instead it saves to the desktop by default. This is a known bug that will be addressed in a
future release of CTDPro.

10. Select another file to download or click Close in the Download dialog box to close it.
Exporting and Viewing Saved Data
After data have been downloaded from the CTD-N and saved to a CTD data file, the data in the CTD
file can be exported to a text file, a file of extension .txt, and viewed. The data can also be exported
to a spreadsheet file or to CTDPost. The specific parameters to be exported can be selected, includ-
ing calculated parameters and the date and time. You can view a text file directly in CTDPro or by
using a text editor program installed on your computer. A spreadsheet program is required to view
and process the data in a spreadsheet. When exporting to CTDPost, CTDPro creates three files:
DAT, C00 and HDR. These files have extensions .dat, .c00 and .hdr, respectively, and are used by
CTDPost for processing.
NOTE.
For the most accurate depth calculation, enter the latitude at which the CTD-N was
deployed, if available, in the Latitude for Depth text box in the Properties dialog box. The
Properties dialog box is shown in Figure 6. To open the Properties dialog box choose
Properties from the File menu.
