YSI Data Scout Advanced - Manual (Page 51)

YSI Incorporated Data Scout Advanced 47
All extract requests and option changes on the Data tab turn “pink” just like test parameter changes using the Edit Test function.
Changed fields on the Unit tab do not turn pink since they are simple modifiers of the extract requests on a per test basis.
All extracted AutoLog pressure/level data coming from a Level Scout are downloaded to the PC in fixed units (psi pressure units, degC
temperature units). However, Data Scout Advanced will automatically convert these extracted data to any other pre-selected
transducer units chosen at the time of actual extraction after Send is clicked. It will be these units that are written to PC files. The
default units are those units the transducer has been set to for reading of “live” acquired data. The Units tab (figure 4.31) inherits, and
initially displays, the default units setting for every test when the AutoLog window is first loaded. However, the user may change these
unit settings for each extract request. To extract a particular test’s AutoLog data multiple times, and write each file in different units
and precision, click Send separately for each request.

Behind the scenes, all extracted data are written first to a special raw file (XRTD.raw). When extraction is finished (or is aborted), this
non-human-readable hidden file is always translated into an AutoLog Test Data (.atd) file, which contains human-readable text.
Optionally, a Comma-Separated-Variable (.csv) file may also be written, which is readable by a spreadsheet application. All these files
are stored in the Dat subfolder of Data Scout Advanced. The two “visible” files are automatically named using the transducer’s model#,
serial#, test#, plus date and time of file creation (e.g., VS2_012300_Test1_2006_09_30_10_56_11.atd or .csv). After extraction, each
.atd file is automatically displayed in the Run window. If extracting data from more than one test at a time, only the last test extracted
is displayed. However, the user can re-display the other AutoLog files later after exiting from the AutoLog window and returning to
the Run window. There, use the File | View ‘AutoLog’ Data files menu function to view an AutoLog file in the Run window.
If the current Display type is Table, the extracted AutoLog data file will appear on one row of the spreadsheet only.
