RMS skewing signal

Katie,

Glad you  got  it working.

The second VI you posted appears to be the same as the original.  I do not see any indexing and both sets of DAQ VIs are still tere.

One last question since you are so helpful.  The three coefficients in the Steinhart-Hart equation change as they cross certain temperature thresholds.  Is there a simplier and neater way to do that than a bunch of case structures and comparison functions?

Katie,

Case structures and comparisons are quite fast and with a few labels can be easy to understand.  Without seeing the specifics of the changes, it is difficult to say whether any other approach would be better.  If you implement the equation using built in LV functions rather than the formula node, switching coefficients might be cleaner.

 If you use the temperature output from the equation as the parameter to be tested to change  the coefficients, it may be important to look at the transition regions to avoid "jumping" back and forth across the boundary.
