How to acquire temperature data from type K themocouple using AD595 amplifier and NI USB6008

[Wallace10]

Thank Jeff,i have tried to put this into the vi,but have this error while connecting the wires"You connected 2 terminals of different types,source is dynamic data and sink is Boolean. Also wondering if my input tp point s of the select vi is right??

Hello all, thanks for your contributions,it's been of great help. I have fixed the error from the alarm option and working perfectly well now using one boolean LED for both temp limit.

However,i'm struggling with the transient response curve fitting vi using DAQ with trigger&gate vi. Any positive idea will b eappreciated.

LAWAL-

Where did you find the transient response curve fitting vi?  If you are simply using the Curve Fitting ExpressVI, how do you have it configured?  What are you seeing verse what you are expecting?  You may have luck looking though some of the curve fitting threads.

Hi All,

I am quite new to labview and I have followed the conversation so far

and it is quite interesting. I am trying to capture the transient response of a thermocouple where there is a change in temperature. i want some help with collecting the x and y values into different arrays to use on the curve fitting vi

Hi Kula27,

Maybe I'm missing something here, but what's the curve fitting VI going to do if you split the x and y values. Why wouldn't you just feed the signal from the DAQ assistant directly into your curve fitting VI.

Also, why don't you have the DAQ Assistant setup as a thermocouple task?

If you want to continually append to an array as you're doing in the for loop, you'll need the shift registers to be on the while loop.

Benny Benson, I got it figured out...
