Hmmm...I've wired it up, but it looks like the output of the derivative VI is an array of the size of the number of samples. And it's producing nonsense values. If the voltage was constant, I would expect the derivative to be zero for example. Adjusting the voltage up would produce a positive scalar, and adjusting the voltage down would produce a negative scalar. How do I convert the output array into a meaningful scalar value? I can provide my current vi if you need to see it..my email is [EMAIL PROTECTED] thx Jeff
