Offset nulling a task with multiple strain and non-strain channels

[pallen]

Greetings,

I have a DAQmx task with 24 channels in it.  12 of these are strain gages that I would like to perform an offset nulling on.  

I have looked at the documentation for the VI and it appears that this is possible.  But I do not understand how to add multiple channels to the Channel input of the VI.  

Is it actually possible to perform an offset nulling on more than one channel at the same time?  

I've noticed that this is not a quick procedure, so performing it 12 times sequentially would not be ideal.

Does anyone know how to null multiple channels at the same time?


Thanks very much.

pallen,

What VI are you referring to? Is it the Cont Acq Strain Samples (with Calibration).vi shipping example? This example is set up to read multiple channels and perform nulling already. Perhaps this KnowledgeBase article will help you out with DAQmx Channel Strings. Also, did you create this task programmatically, or in MAX? Please let us know a bit more about your application, and I will be more than happy to help.

Regards,

Thanks for your reply Ryan. 

I managed to figure out what needed yesterday with a little help from my friendly neighbourhood NI sales rep. 

Turned out I was 80% there.  I just didn't know how to select multiple channels as part of a task subset.


Now I do.

Glad to hear you got it working!
