seconds, and the YSI 610-DM makes sure that cleaning will end at least 30 seconds
before the sample. You set the number of wipes in the Sonde main menu, see Section
2.9, Sonde menu of the YSI 6-Series Operations Manual. When the YSI 610 is started,
the number of wipes is included in the information screen. This allows you to verify that
wiping will occur.
7.8 FILE SYSTEM (610 DM ONLY)
The YSI 610-DM is equipped with 96 K bytes of battery-backed RAM to hold data files.
Files can be created in the YSI 610 itself (by using Logging, Capture or Add) or can be
transferred from a YSI or non-YSI logger (by Kermit or Xmodem). The YSI 610 can
hold up to 50 files. See Section 5, Files for a detailed explanation of how to use the File
system.
The YSI 610 provides flexible access to the files. You can view them at any time in any
order. You can append data to them in any order (provided you are appending data in the
same manner it was originally placed in the file). You can append data to one file, then
another file, then return and append data to the first file again. The only limit on file size
is the amount of unused memory. Deleting a file immediately frees up its memory to use
for other files.
To access the file system, select 610 File System from the YSI 610-DM Main menu. The
Files list appears with a file size next to each name. File names are always unique and are
case-insensitive. At the bottom of the Files list is a note about how much RAM is free.
Select the file that you want to access, and press Enter. The Files sub-menu appears. If
the YSI 610 only holds one file, the software skips the Files list and proceeds directly to
the File sub-menu.
The View Header menu provides you a summary of administrative information about the
selected file. If the file was uploaded from a non-YSI logger, the summary is not shown.
Instead a text viewer is activated, allowing you to view a flat ASCII text file using the
four Arrow keys and the 0-9 keys (0 moves to the start of the file, 9 to the end of the file,
1-8 part-way through the file).
