    "Expert Grill" (Wal-Mart) probes. Anyone else use them? Your settings?

    Being the "Frugal" person I am. I saw that wal-mart has temperature probes for their thermometers. Since they are $8 for a two pack, I figured it was worth a gamble. In the config page of the heater meter I set them up as TX-1001X-OP (Thermoworks Pro Series) with the resist value at 10000 and 0 offset.

    They seem to work. I took an insulated cup filled with ice and water and stirred them using the probes and compared it to stirring it with my Thermapen and it's within .2(F) degrees.

    However, I feel I am missing something. I have not done any PID tuning or anything other than plug and play. I am going to assume I need to do some tuning because the 1hr graph is showing some funky oscillations. If anyone has dealt with the probes, please let me know your settings so I have something to start with. I am not clear on PID tuning. Searched the forums but there isn't really any ELI5 (explain like I'm 5) guides or anything I could find.

    Any help would be appreciated.

    You don't need to change the PID settings when changing probes. Does the noise go away when only using 1 probe? The fluctuation is only 0.5F, which you wouldn't see on a scaled out graph where the scale was more than 1 degree.

    For a test you could put them in the oven and ramp up the temps to 300 and then let it cool down, see what the graph looks like then.

    I'll give that a try. I've been running it for a few days now. It seems to be okay.
