Ben,
I suspect that maybe you are not selecting the option to display the Calibrated Results, as opposed to the regular Results. When you go to create a LabVIEW VI from your script, make sure you scroll through the options, and on the fourth page, you will have the option to select which variables to display on your front panel. Here is where you want to choose the Calibrated Results of your Caliper. Please see the image I have attached. If this doesn't fix the problem, please let me know. Also, it would be really helpful if you could upload your test script, so that I can get a better idea of what your script does.
