temperature stablization criteria

[deniz]

 Could anyone please send me an example of action engine that is illustrating my case? The one in the forum is not that explanatory.

 Which VI or VIs should I use to take the last 10 TC readings (and the 10 before that) and make calculations on them?I tried build array but it did not work.

 Thank you

I spoke with Josh, my colleague, and he mentioned he has been working with you over e-mail.  I will defer to him to continue assisting you.  If anyone else would like to comment, please do so.

Here is an action engine to determine temperature stabilization per UL1778 Section 49

"Temperature change shall be less than 2 degrees C over 3 consecutive 15 minute intervals"

 You feed it a numeric array containing your measurments every 15 minutes to test for stabilization

You might have to change the High and Low limits depending on your aplication in the "Wirte" state.

I use this in a program for thermal testing power transformers and use redings outside of 0C and 200C as open thermal couples.

aeastet beat me to it... 

As I was saying lastnight you might as well remove the highlighted section in the attached JPG.

As I put this in to try and detect open or bad thermocouples.
