6.2 DIRECTORY
Use the arrow keys to highlight the Directory selection in the 650 File menu and press Enter to display the
list of files resident in the 650 memory.
Note that the size of the file is shown in two different ways: (1) the number of samples (logged data points of
several parameters) and (2) the total number of bytes of memory occupied by the file. Highlight the top file
(PROFILE1) and press Enter to generate a display of the details of this file. Press Escape and then highlight
the second file (DEPLOY1) and press Enter to again display information about the file.
For both files, the file name, site name, file size and time of the first and last samples logged are shown. The
information under Interval will identify whether the data were logged by manual control of the system
(Discrete) or to the memory of a sonde set up in an Unattended sampling study. Only for Unattended
sampling studies will the actual sample interval be displayed. When the Interval has the designation
“Discrete”, the time between samples can be determined by viewing the data as described below in Section
6.4.
