Multimeter Temperature Mod

Remember that $4 multimeter that I took apart? Well, I still have it. And its not very reliable nor useful. So, I have decided to make it useful! How you may ask?

My impressions will this whole thing was a big roller coaster, but lets start from the beginning. First impressions, the packaging was fairly cheap and the box looked like it had been through a big journey. The instruction manual was surprisingly well written for such a cheap multimeter and the multimeter and probes felt very solid and quality.
