cursor is already selected will cause the item to be deselected.
All items in the list can be selected or deselected at once using
the "Select All" and "Un-Select All" LSKs.
The “Logs” LSK provides two options - "Full" and "Since Last".
The "Full" option causes
all of the data each selected log to be
downloaded. The "Since Last" option causes only that data
which has been logged
since the last time a download was
completed to be downloaded. Since the logs contain a large
amount of data, the second option will be a quicker option in
almost every case.
Once the desired set of logs to download have been selected,
press the "Proceed" LSK to start the download process.
Download times are highly dependent on the number and types
of logs being downloaded and the length of time since the last
download. Times can range from a few seconds to more than 15
minutes. The more often logs are downloaded, the shorter the
download times will be.
A progress bar will be presented as the download process
proceeds. As the list is processed, each item will show a status
of
“OK”, “In progress…”, “Pending”, “Skipped”, “Active”, or
“Failed”.
Once the download is complete, press the “Done” LSK to exit
maintenance mode.
When downloaded to the USB fob, the data logs will be saved in
.csv files with a unit number prefix (e.g. “1_” or “2_”). This can be
imported into newer versions of Microsoft Excel

in a table format.
The data can then be plotted or analyzed by several third-party
tools. Note that files can easily contain 50MB or more of data.
