Default DVM from the dark ages

This was top of the line a half century ago. But it still works! Five digit resolution, AC converter, all in three rack mountable chassis. The Nixie tube readouts are precious...

or perhaps you may consider it a frequency driven display ;p

I have two counters like that; they are very good and shouldn't be cannibalized. In fact, if you want to sell that plug-in unit I may be interested in it. I can't quite read the markings on its panel. I believe the counter is a 5245L and I would love to have it, but I'm sure you want too much for it. How about a trade for my digital voltmeter?

well, it isn't actually that model, but similar and not rack-mount width. That was just a convenient photo I found on the 'net. Sorry..

That one in the photo is a great unit and wouldn't rape it.

Well one of my counters is in need of a small circuit board. What model do you have? Perhaps it uses that board and we can make a deal. It's a tiny thing maybe the size of a business card, parallel to and close to the front panel on the bottom.

My dad has it back east. I just remember the looks of it. Any trade would take a long time to fulfill

I just played with my good one for a while tonight. Works great, even though these days it's of less value than before. I can read my ham transceiver to 10 Hz and it's pretty solid. Of course I can read the counter much more closely but it's seldom necessary. The real purpose is for fun.

It also has a very good frequency standard in it, with multiple ovens and coarse, medium, and fine frequency adjustments. Keeps warm even when unit switched off.

But I have drifted off topic; once I checked my ancient DVM I took it off the bench and now need to store it for the time when my heirs will toss it in the trash. I have other meters that are plenty accurate.
