What a have is a VI that uses the following SUbvi's, starts with FP OPENvi, then FP Create Tagvi, into a "While Loop" which contains a FP READvi outputting data into a INDEX ARRAYvi outputting to a Display (DBL). This shows the output of a FP-AI-100 monitoring a 9v battery. I have to monitor this battery for a 4 hour period my problem is storing the 4 hours of data and getting it out of the "while loop" into a "Write to Spreadsheet File vi" all I seem to accomplish is just one data sample which I get into a spreed ship file with no problem. I just can't get 4 hours worth. By the way this is my first VI and I'm sel
f trained so have mercy.
