VB20SL ‘.VBO’ file format
The VB20SL data files are saved in standard space de-limited text format. This
allows the data to easily be imported into third party applications such as word
processors or spreadsheets. The files each contain a header section before the main
data that describes the channel content and information about the VB20SL such as
serial number and firmware version.
The [Column names] parameter specifies the data in each column of the data
section.
An example of a VBOX VBO file is shown on the right.
Note that the File created time and date is derived from UTC time and date, so will
not reflect your local time unless you logged data on the Greenwich Meridian.
