message. This note is then saved as a header in the data file set and can be viewed
along with the data.
You can either choose to have data logged continuously until ‘Stop’ is selected
from the Data Logger menu, or you can choose to set a time limit for data logging
by checking the box labelled ‘Time Limit’, setting the duration in the ‘Run For’ box
and selecting units with the drop down list. For example if you wish to log data
for thirty minutes type ‘30’ in the box and select ‘Mins’ from the drop down list.

Running the Data Logger
If you wish to save the data into a file for later use, check the ‘Save to File’ box
before selecting ‘Run’ from the Data Logger menu. You will be prompted for a file
name and location before data logging commences. The file and path information
will appear in the box at the top of the page labelled ‘Data File Name’. If you
forget to select file saving before starting a run, you will nevertheless be prompted
at the end as to whether you wish to save the run data.
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’.
‘Data Logger’ and ‘Resume’ 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 as a set of
files, each with a date suffix in brackets in yyyy-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).txt’. The data logger
