Solartron 7081 - Reference Circuit

[Ismsanmar]

Just adding a little more information to the connector debate, I have recently bought a couple of original cables on eBay, which are optional accessories, not the one that is suplied with the multimeter. Specifically, the 3 Terminal Input Lead 3193 and the 5 Terminal Input Lead 3183.

And yes, the insulator between pins is PTFE, as in the socket, which makes them a special order by Solartron and truly a unobtanium connector. Here I add a couple of photos of the original next to the copy I bought at Aliexpress. You can see that the pins are a little bit shorter in the Aliexpres connector.
