Why is there a time delay in my while loop

I thought it should too, but our data just gives us a voltage in the A column in Excel. It gives a starting time along with a description of the data on the first spreadsheet but besides that there is no time values exported.

Check the data on the group worksheet not the root coverpage

Looking at things from another perspective, you could simply record both voltage and acceleration simultaneously from the start and after you have all the data, search your voltage array to find the index of your target voltage then pull the acceleration data from it's array beginning at that index.

That will give you the position in the acceleration array you want to start with.  You can pull the subsets from each array as needed to lose any unwanted values.  Your tasks will need to be configured to run at the same frequency so each data point is collected in (or near) parallel.  At the same time, you could just cluster one of the arrays and add in a time stamp as needed.

Those devices will not support multi device Tasks

Acknowledged.  I was actually thinking running the two tasks in parallel vs as ingle multi-channel task.  You risk a little bit of a bias in timing but it all depends on what level of accuracy is needed if that approach would work.
