Scxi 1122 - strain gauge measurement problem

[Setu]

Hi all,
Has anyone ever used scxi 1122 and 1322 with labview? If so could you please post a vi so I could check my setup here?

I am measuring 8 quarter bridges with scxi 1122, 1322 and labview. I am using quarter bridge II configuration in MAX and a dummy resistor for half bridge completion. I need to get the mean of 100 samples for each channel.
If I configure AIConfig, AIStart and AIRead to scan rate of 100 per second, I get the wrong numbers to the test panel in MAX. If I scan each channel 100 times, then average them, it takes longer than a second.

Can anyone please suggest something? Perhaps I have wired them up incorrectly to the terminal block.

Thanks,
-Setu.

Hello;

If you go to www.ni.com and type +labview +1122 in the search field, the second result is a Labview example showing how to program the SCXI-1122 module.

Furthermore, you can download the SCXI-1122 from www.ni.com, to double check if you made the proper connections and configuration.

Hope this helps.
