Accessing the files
If the logger was configured to generate files, a new drive letter or mounted device will
appear. The device name will be created from the serial number of the VFC400-USB. You
can access the files by browsing to the newly created drive and double-clicking the PDF,
CSV or LTD files:
l
If you have selected PDF as one of the files to be generated, you will find a single
file with the .pdf extension, containing the data for both channels. For PDF files,
you need Adobe Acrobat Reader or a similar PDF viewer.
l
If you have selected LTD as one of the file types, you will find a single file with the
ltd extension, containing the data for both channels. To open the LTD file you need
to install the free Control Solutions VTMC software.
l
If you have selected CSV as one of the file types, you will find two files with the
*.csv extension, one for each channel. CSV files can be opened with a text editor,
or imported into a spreadsheet program such as Microsoft
®
Excel.
To retain the logger-generated files, copy them to a permanent storage location
on your computer, such as the
Documents
folder, as they are not automatically
copied.
The data on the logger is retained. Each time you plug the VFC400-USB back into
the computer the files are re-generated, until the device is re-configured. Once
the battery is exhausted, the real time clock on the unit stops and dates and
times for the retained data may no longer be accurate. You will, however, still be
able to access the last trip's data.
