So I'm very new to LabView and struggling to understand the example code for the C Series NI 9237. I've set up my load cell, module, and the LabView Getting Started NI 9237 example code. So far everything is working and I can see an input from my load cell.
However I was wondering if there was an documentation I could read on this example program about the parameters on the FrontPanel. I don't fully understand many of the input parameters (For example Poisson's Ratio) and the meaning/effect it will have on my data. My load cell spec sheet doesn't specify a lot of the parameters besides Bridge resistance.
I also don't understand the graphed output either, and why I have essentially four data lines and the FPGA error out.
The example code can be found under the NI 9237 example finder

Thank you!

Quick edit. The example code can be found under the LABVIEW example finder

I would look at the other examples that show up under an Example Finder search of "9237"
Good links:

Terms not explained in the code may be more general terms that could be read about in a text book or similar source.

If you open the host VI and follow the control, you will see that Poisson's Ratio gets used in
