Is there functionality in DF to store a 5-value calibration array per channel so that calibration is applied to each value read from, say, a load cell?

Sure.  Use a Conversion on the channel.  You can either hard code the 5 values into each Conversion, or use variables that you then persist to disk using one of a variety of methods.  Which method to use depends largely on exactly how many total values you expect to persist.  The easiest way is to create a Test D to A channel for each value with a History of 1 and a Persist of 1.  But if there are a lot of values to store, you'd be better off using the File. functions to store them to a flat file.  Of course if you are using the program internally using a development version of DAQFactory and don't need to change them often, you can just put the values directly into the Conversions.
