resistance at t0

[Faezeh]

Hi, I am using the DAQ assistant to get continuous resistance data from an LCR meter. I also need to plot the change in resistance since t0. How can I extract the resistance value at t0 so I can use it in my calculations?

If you are using the DAQ assistant, does the wire come out as a dynamic datatype (blue wire)?  If so, convert it to a waveform data using one of the express VIs.  The waveform datatype is a bundle of 3 values, a t0 time, a dt time interval and a Y array of data.  Unbundle the Y array and use index array to get the zeroth element.

Thank you so much

How do I unbudle the y array?
