I just got one of these units.
Anyone know why my temp probe reading would oscillate with a 2 degree Fahrenheit difference (eg 89 degrees, then 91 degrees, and back to 89 degrees every second or so). I’ve used the temp probe that came with the unit and a second PT100 probe from Auber. Anything come to mind that I should look at? I’m wondering if it is the audio connector port? Wiring to the PID controller, etc? I’m not an electrical engineer, so anything would help.
Cheers

my guess is if its not the probe its the way the pid works... perhaps theres some filter setting you can adjust for this but it may just be related to the logic and design used in this economical pid design.
