For the volt and ohm nuts, the interesting stuff was across the hall in the standards lab.
Dave,
I wanted to update this comment as I saw the standards lab video after I made the above comment. The standards lab tour was disappointing as I do not dabble in time and/or frequency. My hobby lab is all SMUs, voltage references and calibrated resistances, DMMs, nanovoltmeters, picoamp source, nanovolt source, etc.
Your host mentioned the "cells" across the hall. I think he was referring to their voltage standard boxes. Probably Fluke 732Bs.
If you get a chance to re-visit this standards lab, please ask for some discussion and eyes-on of the voltage and resistance standards.
cheers....
