There is a Custom button on the LoggerNet Connect screen that allows a variety of different data collection tasks, including collecting a range of data between dates.
Note that, by default, data collected in this manner is stored to the C:\Campbellsci\LoggerNet\Data directory. This is a different directory and different file than where the data is stored from the LoggerNet scheduled data collection and from the Collect Now button on the Connect screen. (Scheduled collection and Collect Now data go into the same file and use the same data collection pointers.)
