To record the data that is shown on screen, go to the
Toolbar and click on Logging > Start Logging. A window will
pop up on screen asking for a file name for the log file to be
captured. DO NOT change the file type, as LabVision must
record the log file as .Csv. As soon as file name is confirmed
by clicking on ‘Open’, LabVision begins capturing the data
immediately.
Also notice that the status bar has changed from blue to red.
This demonstrates that LabVision is recording to the log file
specified. The amount of data collected can be limited to a
certain size inside LabVision. When a maximum memory
limit is set, this results in over-writing previously written data
in the same log. Therefore it captures the most recent
amount of data. To prevent this from occurring this feature
can be turned off by clicking on Options > Options > Logging
tab and uncheck the parameter ‘Limit Logfile’. With this
feature disabled the log file will be dependent on time as
opposed to memory size.

When logging is complete click on Logging > Stop Logging.
Notice that the status bar has changed from red to blue. This
informs that Logging is complete.
