I think I ran into this or a similar issue trying to use a type K thermocouple. Graphing internal temp and AUX DC voltage with a K type thermocouple both of them are on a constant slow creep – internal temp on the way down, aux voltage on the way up. When looking at the temp on the main app screen temperature is stable. Is there any way to use graphing with the thermocouple so that it displays the compensated temp rather than the aux DC voltage?
