One last question: is there any polarity on the RTD itself? Or will it work no matter which side I choose for the pin 8 connection?
I finished up my other little project
(or least got the plane back together, still need to fly once the WX clears), and will hopefully get to this one soon.
Makes no difference, an RTD is basically a resistor so you can connect to it either way. Just keep the power wire with the + sense wire and you will be fine.
