shunt calibration NI 9235

[WyoEng]

How do I wire strain gage for shunt calibration (is it different wiring than normally without shunt calibration?) and programmically set up shunt calibration at DAQmx level (not DAQ assistant)?  I've got 50 feet of lead wire that's going to be added to 10 foot lead wire on 120 ohm resistance strain gages, and I need to be able to calibrate properly to take the resistance added into consideration so that we get the correct strain readings.  I've looked at http://zone.ni.com/reference/en-XX/help/370466W-01/measfunds/quarter1/#GUID-F34636DC-B311-4257-BDD0-... and http://www.ni.com/pdf/manuals/374645a.pdf#page=11 strain gage and NI 9235 related manuals, but they don't completely outline how to do this.

I'd greatly appreciate any help anyone can offer.

Thanks!

Hi, here is an article that clarifies your doubt but with a different module. Now, in your case, in figure 5 from the 9235 manual states that there is a 50 kΩ internal Shunt Resistor. In summary, for the acquisition you just need to configure a strain task and input the sensor data that comes with the calibration certificate. I hope this helps
