Ronan calibrators.
jchw4:
Somebody recommended them as a cheap voltage source, but there is absolutely no information on them.

Some time ago I bought a Ronan X85 Calibrator as a nice weekend project.
The only data I could find was a brochure basically saying that it exists. No manual, nothing else. >:(
The unit was sold as "Used, fully working".
As received: nothing worked. Display lit with all zeroes, none controls worked, output was fixed at around 4 volts....
I kind of expected that something could not work, but not all. :-//
The first thing I noticed was that it had a charger, so it probably had a battery.
A bad sign, since the 80s it could corrode through.
But as it was a "weekend project" I decided not to return it.
As you can see, corrosion was not that bad. It was probably stored vertically and the acid did not reach the boards.

It's interesting that different boards were probably designed by different people. Just look at these traces. ::)

I have never seen this battery type.
Does anybody know if it was a custom or just abandoned type?
