I have a PXI-SCXI combo chassis and iam using SCXI-1520 for my measurements,whenever any data acquisition program i run,for my first iteration it's reading a high value(i.e max limit of DAQ card of 9.99V)and after that it's reading correctly.This happens first time when i run the program.If i stop and re-run again everything is reading correctly,But if i make any configuration change and run it again it behaves differently as mentioned above.what could be the reason?
That does sound like bizarre behavior. What version of NI-DAQ and LabVIEW are you using? Which PXI combo chassis are you using and what kind of data acquisition board are you using? Do you observe any of these unusual readings through MAX? Reply with some additional information and we can investigate further.
