operation on acquired data

[deniz]

 Hello all,

    I am taking a thermocouple reading by using FP-TC-120 module. I need to take last 10 readings of the thermocouple data and calculate the standard deviation of it. With the current code I have it returns that SD is 0 or NAN. How can I do what I want to do?

 Thank you

FieldPoint modules don’t have a buffer on them.  This is probably why you are getting these values returned to you.  Therefore you will have to store the values into an array to be able to access previous values.  From there you can use the array subset like you have to get the previous 10 values.
