Temperature dependent resistance

[sirtaza]

Hello everyone,

This is my first post on this website. I have started working on Pyxis Schematic few months ago. I want to model a resistance whose value varies with temperature. I have a complete data set available from which i can retrieve a second order polynomial. There are few problems: first of all the second order does not exactly fit the curve, so there is a mismatch in resistance values. secondly, is it possible to model the resistance higher than second order polynomial. Actually my target is to model a bolo meter ( whose resistance varies with temperature).

Please help me in this regard. and if you feel i am not clear with my question, please let me know.

Thanks,
Syed Irtaza Haider

I am not familar with Pyxis....................can you call a function.........a function that will do a table look-up? intrapolating between the table vales?
