First thank you for doing this. I managed to import from a spread sheet , instructions on importing could be better..? However the data was full of bad readings as I had to guess some of them. . I would like to be able to use the graphical display to adjust the curve. Basically adding some movable points would be great. I am using this for a kiln controller and hope it works as my trial and error method is very time consuming as it takes a long time and uses a lot of energy to keep heating a kiln. To try and use this tuner I used a step input with just a guess at the controller settings for PID. How does this value that I used affect the results of this tuning system? should I be setting the PID to 0,0,0? help please.
