Hi, I recently got a K8067 thermometer kit, but it doesn’t seem to be working. I only get around 130-150mV from the output. I’ve connected the resistors to ground in parallel as it says in the kit manual (I’m using 4 x 1k). The other thing I noticed is that R11 is getting hot.
I’ve checked for shorts, but I can’t see anything.
If R11 gets hot, most likely you have inverted ZD1 or there is another assembly problem.
Make sure the IC is inserted the correct way.

If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
