Reading list from configuration file python Good day, tldr; Configuration read script returns single characters instead of strings. I haven't done any PID tuning or zone stuff yet, so I can't help that much, lakeshord I did notice that at least with the you have to do more than load the zone table, you also have to set the "mode" to "zone" rather than "closed-loop" in the "Configure Heater Output.
The vi reads the first temperature and then sets that as setpoint of the PID controller. What I want it to do is read the first setpoint, pass it to the output, then wait for some time say 1 hr, which is adjustable and then read the second setpoint and so on.
These can be greatly effected by distance to the heater and the thermal resistance of each interface between the heating element and control sensor.
Also how do we know the best values of PID setting to run the experiment.?? I will give it a try.
Michael Santiago 6 2. If you can not get good temperature control in manual mode, you will likely NEVER get it via software control the software drivers will simply take over the role of you pushing buttons.
This is the way to do it and this is the How far is the temperature sensor from the heating element? Your model may be different, of course. What is the vi that is taking the output from it? Message 2 of 9. Lakdshore learning about the basics of LabVIEW programming, here are some great resources for getting started.
The problem I am having is that when I run this vi attachedthe setpoint indicator on the temperature controller the hardware goes to zero and stays lakehore. Derek Lim 93 When you 33 only lakeahore to plot data of the current sweep you need to delete the data stored in the shift registers aka feedback nodes when you start a new sweep! I would recommend trying out the VIs in that library to see how they work.
A portion of it can I am interested in reading the MAV bit 4, which should be set if instrument has something it would like to send It would be a great help if you could clear my queries I know we have to manually tune it but is there any other method of doing it. Below K, the stability of the controller begin to deteriorate and below K it is very difficult to control the temperature.

For tuning specifically, this table http: Esben Jensen 11 1 6. I do not know how to go by P and I values for different temperatures that will allow me to record labivew spectra at least for 10 different temperatures per day. Message 7 of 7. If so try to debug.
