  • Answer:

    This type of application isn't possible with this logger due to a few reasons.  First, the logger doesn't have a real time output so it won't log while connected to a PC.  The USB jack is only used to plug the logger in for configuration and to download data after its been recorded.  The other reason is that the software can only connect to one logger at a time.  You can use two loggers if you wanted and then open both data files within the software to compare the two.
