The blue progress bar displays the state of completion of the run, and the blue box
to the right of it the same information as a percentage. You can stop the run at
any time by selecting ‘Stop’ from the Data Logger menu. The yellow Status bar at
the bottom of the page gives information about the data logging operation.
Once data logging is complete you may open the text format data file using any
compatible spreadsheet programme such as MS Excel, and use the data to
generate plots and reports.
You can pause the data logger at any time by selecting ‘data logger’ and ‘pause’.
Repeat to continue logging from where you left off, noting that the clock keeps
ticking during the pause period.

Auto Date Stamped Files
If you are planning to run the data logger for extended periods of time then you
should consider checking the ‘Auto date stamped file’ option. This feature will
save the data at midnight for the previous twenty four hours and so on until the
data-logging is complete OR the user interrupts. The data file is stored with a date
suffix in brackets in yy-mm-dd format.
This feature ensures that data is saved periodically in sensible sized files. This
will prevent the computer from crashing and will also ensure that the data is small
enough to fit into an Excel spreadsheet
As an example, the user wishes to run the data-logger for seven days recording
every minute starting at lunchtime on 12th November 2005. He starts the data
logger with the auto-date stamp function enabled. When prompted he gives the
filename as test1. In this situation the data logger will run from lunchtime to
midnight and then save the first file as test1 (2005-11-12). The data logger then
clears and continues for another twenty four hours until midnight the following
day. The data is then stored as test1 (2005-11-13). This will continue for seven
days when the data-logger will finish.
After this the user will have a sequence of files:
test1 (2005-11-12).txt
test1 (2005-11-13).txt
test1 (2005-11-14).txt
And so on. Combined together they represent all the data over the last seven days.
Note that the Rapidox uses the computer clock and date to perform this action, so
make sure that they are correct before starting a run.
To view the data in its entirety the user would need to load each file in turn back
into Excel to combine.
