In sciences/technology/engineering, wording is paramount. If the reader can't make a picture as it reads, nothing will come out. This time you have it ! and w/o Mathcad sheet. What about some NIST input/output card ? To a certain degree, Mathcad and NIST are convivial friends. It is so true that you will find the Mathcad DAEP "calibration of T/C's [Thermo Couple]" in their system.
So, Mathcad holds two data files as "sample & hold" Z-1, Z, you need that whatsoever for the Process Control Engineer/Optimizer "expert system", then spool back to the "User".
Preston, does it make sense (the diagram) ?
So, you have or will have the "Expert system", collabs will help script if possible, Preston & his client will be happy & Jean too.
