DAQ Measurement Analysis

[rajeswari]

Hello Team, i am using NI USB 6225 DAQ using Labview 8.6 version, after I got measurements from one of the AI channels, for suppose say 15 to 30 samples I want to know whether the data points are going to raise or whether they are falling down or are they fitting in some tolerance value. I want to know is there any polynomial function thats suits to my exact requirement , I could find out Mask & Limit Test.vi to find the values in some +/- tolerance value but i couldn't find out whether the samples or going to raise or falling... Could you please let me know any solution for this.                                                                   Thanks In Advance.

In LabVIEW, under Mathematics -> Fitting.  You should find all the models that you need.  If you want to find out is something falling or rising, you can use a linear fit and extract the slope.
