650 MDS Section 3
At the end of the 90 minute profile determination, the user either confirms the Stop logging command by
pressing Enter or simply presses the Escape key to return to the sonde Discrete sample menu, highlights the
Close file selection, and confirms the file closing by pressing Enter.
The profile data taken at a 16 second sample interval is now stored in the sonde memory under the file name
PROFILE1. It can be viewed on the 650 display and/or uploaded to the 650 memory or directly to a PC by
accessing the sonde File menu.
3.5.2.4 SONDES WITHOUT MEMORY
If your sonde is a 600R, 600XL, or 6820 purchased prior to September 1999, it may contain a circuit board
that does not have memory. With sondes of this type, you will not be able to log data to the sonde – only to
the 650 as detailed in the following section. With these no-memory sondes attached to your 650, the Run
display will show a blank Sonde logging window as shown below.
