Here is my problem;

I tried to adjust the nominal gage resistance in my PXIe-4330 in quarter bridge configuration. I get mentioned error at DAQmx Start Task.vi when trying to configure a strain task by Cont Acq Strain Samples.vi.

Hi Tresa,

That error message appeared because you were trying to specify a gage resistance which is not supported by the module of the software. You must specify the Nominal Gage Resistance value into 250.00 if you are trying to configure using Quarter Bridge. You must remember that  the PXIe-4330 supports gage resistance of 120, 350, and 1000 Ohm. See the illustration below:
