I really look forward to seeing more on your multi-slope integrator. Not much information out there for doing such a design with discrete components and op-amps these days. Great video as always!
Great video. Those Peak Atlas jobbers really do work well. I have the old DCA 55. It gets confused by IGBT's and some SCR's but other than that it's brilliant. Those little 1 inch CRT's generally have an anode voltage around 800V. Of course so the X/Y plates are around ground potential the cathode is usually down around -800V and the heater needs its own separate winding on the transformer👍
Nitrogen filled resistors? I didn't think such a thing existed. But I found that BI Technologies apparently makes nitrogen filled hermetic resistor networks. I found it interesting that the industry went straight from 6.5-digit DMMs to 8.5-digit ones, and that 7.5-digit ones didn't come until a few years later. I think the Datron 1071 may had been the first one.

The industry trend toward full colour touchscreen HMIs on everything is one of my pet peeves. Even Mart Carts have them now.
