Checking out a Heathkit IMD-202-2 NIXIE Meter

I picked up another one of these things at Dayton, quite literally one of the few NIXIE devices I saw there this year. These meters were part of a class where you built a device and learned how it worked. While "work" is subjective for a given value of "work," it does measure things somewhat inaccurately. It also requires constant adjustment, so if you like that - this is for you! Let's check this device out. I apologize, the device tends to drift off camera for a short time, I'm still getting used to doing video of my projects.
