YSI 610DM - Manual (Page 19)

YSI Incorporated Displays and Loggers 17
The Mark feature of the YSI 610-DM allows you to store data from several sites into a
single file. You can only create a marked file using the “M” key prompt during Run
mode. You may upload the file to YSI EcoWatch for Windows software just like any
other data file.
Example: A typical application would be a horizontal profile on a river or lake studying
the effect of location on readings. At each site, you would place the sonde in the water,
wait for readings to stabilize, select a name from the Site List, and store a set of readings
in the “marked” file. At the end of the study, you will have one file with data from many
sites. Each set of readings includes a Mark Number identifying which site the readings
came from.
To use the Mark feature, start by building the Site List. Normally, the Site List includes
pairs of file names and site names. Marked data goes to only one file named “marked”.
Since there is no need for other file names, the YSI 610 interprets the Site List as pairs of
site names and site numbers. Use the Site List “File” item to hold the Mark Name. Use
the Site List “Site” item to hold the Mark Number. The Mark Name can be anything you
wish, but the Mark Number must be numeric, -99999 to 999999, usually 1, 2, 3, 4, etc.
The YSI 610-DM stores a site number in the data file, not a site name so it is important to
remember the association of the number with the name.
After building the Site List you are ready to use the Mark feature. You may choose to
add a single set of readings to the Marked file, or capture sets of readings to the Marked
file as fast as they come from the sonde. Start by pressing the “M” key while in Run
mode. Choose a name from the Site List. Next, choose whether to Capture or Add.
From this point, proceed as any other time you would Capture or Add. Press “C” or “A”.
If it is the first entry to the Marked file, the YSI 610-DM prompts "New File yn?". Press
“Y” to create the file. The YSI 610 then prompts you for Weather information. If you
want to enter Weather information, press “Y” and enter information. Otherwise, press
“N”. Next, the YSI 610 indicates that it has added a single set of readings to the file or
that it is capturing data to the file. To terminate Capture, press the “C” key again. You
