down menu. All graphs may be cleared simultaneously by
clicking on “Reset Graphs” located on the menu bar.
When the “Graphs” window is closed, all parameters
selected for graphing are automatically saved to a .csv data
file, and may be viewed using a spreadsheet editor such as
Microsoft® Excel. Each data file is limited by a maximum
file size of 32,768 (2
15
) lines of data. The data file is named
“Turbocor Service Monitoring Software#.csv”, where # is a
unique file number automatically assigned. The data file is
stored in the “$Turbocor_Install_Dir\Turbocor Inc”
directory (typically “C:\Program Files\Turbocor Inc”). Data
files left in the “$Turbocor_Install_Dir\Turbocor Inc” for
more than 15 days are automatically deleted.
The parameters plotted may be played back by loading the
stored data file. From the “File” menu, select “Open”. Go to
the “$Turbocor_Install_Dir\Turbocor Inc” directory, select
the desired .csv data file to be loaded, and click on “Open”.
The stored data begins to playback on the graphs. The
playback speed may be adjusted from the “PlayBackSpeed”
menu.
