SECTION 7 ANALYZING DATA WITH ECOWATCH
FOR WINDOWS
7.1 INTRODUCTION
EcoWatch for Windows has been supplied on CD-ROM with your Model 9600 and is intended to be used
to facilitate the analysis of data from the nitrate monitor. It is important to understand that several of the
commands in EcoWatch for Windows will not be relevant to applications involving the 9600 since the
program was also designed to provide direct interface to YSI 6-series sondes. As explained above, users
MUST interface to the 9600 using NUview software, and thus the portions of EcoWatch which deal with 6-
series sonde interface cannot be used with the 9600. These unusable software commands are identified in
the following section.
Users should also be aware that ONLY 9600 files that have been uploaded in YSI Data Format can be
opened with EcoWatch for Windows and that ONLY these files will provide calculated nitrate
concentrations. These EcoWatch-compatible files are characterized by a .DAT extension. Users who have
uploaded files in .CSV (raw data with no nitrate calculation) format must use a spreadsheet to view the
data.
With these limitations in mind and, as was pointed out in Section 5.3 above, there are very few
circumstances in which users should not upload their data in YSI Data Format (.DAT) and open it in
EcoWatch. If users want to customize their data presentations at a later time using spreadsheets such as
Excel, the data can be exported from EcoWatch in a spreadsheet-compatible format as described in Section
7.4 below and in Appendix A at the end of this manual. Use of the .CSV file upload format is designed for
users who want to use their own algorithms for conversion of raw absorbance data to nitrate concentrations
and/or for diagnostic use in troubleshooting operations.
7.2 INSTALLING ECOWATCH FOR WINDOWS
EcoWatch for Windows software must be used with an IBM-compatible PC with a 386 (or better)
processor. The computer should also have at least 4MB of RAM and Windows Version 3.1 or later.
To install EcoWatch for Windows software to your computer, perform the following steps:
• Place the EcoWatch CD-ROM into the CD drive of your computer.
• Use Windows Explorer or My Computer to view files on the CD-ROM. Double-click on the
Setup.exe file.
The display will indicate that the set-up routine is proceeding. Follow the instructions on the screen as the
installation proceeds. For most applications, the default settings should work without problems. After
installation, there is no need to restart the computer.
