content: You could try making one? A cylinder of insulating material (nylon, teflon?) that will fit inside an existing existing plug that will donate its case (something of similar size, obv, XLR?). you can get the inserts in strips, solder the wires from your cable on and use epoxy to insulate the joins from each other. You could the fit the whole thing into your case. I still think that removing the front panel entirely, fitting your new terminals and then reinstalling it would be the way to go. I fail to see how that would affect the cal in any way.

content: I bodged a male connector to fit into the front panel socket. Using my 7 decade 100kohm KVD driven by a 10V source, and my 7081 in ratio mode, the combination shows a linearity of 1ppm to 2ppm except for the 6666666 KVD setting, where it is 2.8ppm deviation.Key points of the bodged connector:the pins have to be 1.35mm diameter, and it is a pain finding that. I've found two options: an RS211-4252 ferrule, orsomePoGo pinshanks(last picture)the pin location is determined by holes in a PTFE sheet. Drill the holes undersized; the PTFE is soft and can easily be deformed by the pin. My sheet is 1mm thick, which is too thin; 2mm would be betterthe connector body is a copper plumbing pipe, external diameter 12mm. Obviously it does not latch into positionA little ingenuity is required to create a connector body where the PTFE insert is held in fixed position relative to the connector body. I simply made the PTFE insert have a 12mm diameter, and sandwiched that between two 12mm OD copper pipe sections. Those two sections were held together with a copper pipe with internal diameter of 12mm.It might be possible to create an insert for a real connector body, using PTFE and the pins. I suspect the challenge would be to ensure the insert cannot slide up and down inside the connector.

content: Quote from: Neomys Sapiens on May 06, 2018, 11:21:05 pmThanks NS for the tip, it seems that ODU F-series has at least a similar looking footprint and pin size.@tggzzz, or who has an eye for the mechanical layout, could you please verify if the layout is similar, as far as I remember the l original connector, was not only mechanically keyed on the outer shell, but it also has a different spacing between the rows of pins.BTW @tggzzz, it's a nice connector that you've build there, but I don't have the skillz, even if I have some pogo pins somewhere.The ODO datasheet for the F-series is at:https://www.odu-uk.co.uk/fileadmin/redaktion/downloads/downloadcenter/catalogues/ODU_MINI-SNAP_F_Circular_Connector_Series_F_EN.pdfThe suitable pattern seem to be on page 26, but I have just a faint clue how to build the right plug code out of all these options, if someone more experienced could lend a hand, it will be very nice if we can close this topic, Solartrons 70xx series are nice instruments IMHO and deserve a nice test lead.Cheers,DC1MCNinja Edit: Sheeeit, looked at the Digikey prices: 50EUR+, no rest for the poor, probably were used on some military or aerospace application in the '80ies and bam, 600% price increase for a connector with a production prices in single euros, if sohttps://www.digikey.com/products/en/connectors-interconnects/circular-connectors/436?k=&pkeyword=&pv28=1214&pv88=24&FV=fffc0773%2Cffe001b4%2Cffecf2e5&quantity=0&ColumnSort=0&page=1&pageSize=25And nothing is stocked, those Digikey guys are smart.

One group has a narrower gap than the other.My connector ignored the mechanical key. It is thus mechanically adequate rather than good. The pipes are a reasonable electrical/thermal approximation to the real connector.QuoteNeither did I - before I was forced to make that connector.

content: Fischer connectors - not compatible to anything else, and very expensive. They have more variants of connectors that you can ever countI'd recommend you to contact a german representative with a photo of the "Buchse" (and where it is used, maybe they can remember this customer Solartron) and your guessed type number. They should be able to figure out if this is the corrent number and may even sell you the plug in single quantities - but be prepared to pay a high price. Don't know if they deal with individuals, but back then in a former company we've bought these connectors directly from a representative in rather small quantities (some ten per order).

content: Hello everybody, first of all, thanks everybody for the pictures, it seems that the mounting is not as bad as I was expecting it. actually is pretty simple to unsolder and replace the connectors.I believe one member have said that the size is M15, that means the hole is 12mm in diameter, can it be confirmed ? Because if we change the connectors, at least not drill or affect the panel.Now for the few forum members, is anybody else willing to call the Fischer, I'll take two connectors, one for a 2-wire lead and one for a 4-wire lead. Should we try to do a collective order ?Or should we replace the connectors in a consistent way and invest the difference in hi-quality shielded test leads and Kelvin clips ?Knowing my luck, after I'll change the connectors and invest in the test leads, somehow the market will be flooded with cheap or reasonably priced original test leads, if I'll keep the connectors, most likely I'll finish my reincarnation and not even see an original Solartron lead.But whatever the conclusion of the forum is, I will go with the crowd wisdom and do it as such, specking of which, what are some good quality shielded leads with and without Kelvin clips.And what are the favorites for the new connectors, here I'm listing my finds as well:https://www.ebay.de/itm/GX12-Luftfahrt-Rundstecker-Stecker-und-Buchse-Durchmesser-12mm/132576372856https://www.ebay.de/itm/LEMO-3-5-PIN-BREVETE-S-G-D-G-Circular-Push-Pull-Connector-FFA-3E-650-CLAC11/273030611729And for the Teflon or other plastic type original guy, I vote to pick up the least expensive compatible one, if one of bio-Germans will give a call to Fischer, just to get a price and availability, I'll be grateful, if not I'll try to do it, but they may close the phone)Waiting for your opinion,DC1MC

content: Quote from: DC1MC on May 08, 2018, 06:26:31 pmAs for me, I doubt I will use this instrument much, as I have lots of other DMMs (and it is rather big). Didn't even bother to look whether it works. And I do have a plug. But a colleague got the second 7061, and he did not luck out. Coming to think of it, this might well be the source of the 7061 in the OP, so he wouldn't need one.Anyway, his mind is currently stressed with other things.M15 should not fit in a 12-mm hole, as it's diameter is (as the name suggests) 15 millimeters.I might be a "Bio-German", but there's one thing I just hate: Making telephone calls (which explains in part why I don't have a mobile phone).I don't think Solartron's engineers were all wrong. The idea of needing just one connector (with excellent handling qualities) has lots of appeal. They probably hoped to set a standard with others to follow, but that didn't work out. If it did, they'd be commonplace now.

content: Quote from: Kosmic on May 10, 2018, 11:05:58 pmIt appears that the outer insulation jacket is PTFE but it does not state what the individual wire insulation is. That is sufficient to prevent external chemical/UV/etc damage to the cable.However, I've seen quite a few cables where the individual wire insulation is something else, e.g. PVC. That is, if you are fussy, less good with respect to insulation and leakage between wires. Whether that matter is a separate issue, of course.
