Can a VI Logger Task be Offset Nulled?

[eroberts@water.ca.gov]

I would like to use VI Logger to datalog pressure transducers (strain gage type) using SCXI-1520/SCXI-1314.  At rest (0) I read approx 600mV that I would like to zero out.  Can the Vi Logger task, or NIDaqMX Task be Offset Nulled to provide a zero balance of the strain gage bridge?  Thanks.

Hello eroberts,

Thanks for your post!

I feel that the best way to offset your pressure transducer would be to use DAQmx functions. There is a DAQmx Perform Bridge Offset Nulling Calibration.vi that I feel would be best to use for your situation. You can find this function by going to Measurement I/O >> NI-DAQmx >> Advanced >> Calibration >> Bridge Null Cal. Also take a look at the following knowledge base that also talks about doing a null offset. Let us know if this will work for you and please post back if you have any other questions!

Cheers!
