Custom Scale does not exist in subSCXI Bridge Shunt Cal.vi (Error 200378)

[usuario]

I have this .vi where I can acquire strain & temperature data, with a SCXI chassis and 1520 and 1314 modules. I want to shunt calibrate the wheastone bridges but I get this ERROR 200378. The .vi is based on a LabView Example, from wich I've copied the subvi. If I set the 'perform shunt calibration' to false it works fine, even nulling the initial offset.

How can I fix this custom scale problem? I actually don't want to scale the signals since the units I read are deformations (graphed x10^6 in the .vi).

Guess it's a simple matter but don't know how to solve it. Thanks,

Hi usuario,

     I think I'll keep posting in English in case it may be helpful for non-Spanish speaking users. I guess this errors comes from not creating a Custom Scale for your application. When you set to true the boolean control 'Shunt calibration' in order to perform shunt calibration, this error takes place because you have selected 'From Custom Scale' in the constant cabled to 'task in' and LabVIEW is not able to locate that Scale.

     I think this link may help you in your programming.
