I am trying to create 2 strain channels and use one of them to trigger data acquisition because this is for an impact test and the sampling rate needs to be high. I am using DAQmx Reference Trigger to trigger data acquisition once the strain value exceeds 0.00001 which is a pretty low threhold. However, I am not able to trigger the data acquisition even though the strain value well exceeds the threshold.
I am using LabVIEW 2013 Professional Development System, NI cDAQ-9174, NI-9237, and NI-9945. My vi is attached.
Any help would be highly appreciated!
