Well despite whatever seems to be going on with the sine wave, I put the new thermocouple in the oven and it behaved in a Rocksteady fashion. This should make controlling the smoker easier. The Auber thermocouple is fairly small diameter and responsive, way more responsive than the thermistor probe from thermoworks or Maverick. What I have found so far is it trying to control off of those thermistor probes is poorer then a thermocouple because of the added lag time of the higher Mass probe.
