I make it short: it's just a short
Project is in Public Domain and the actual project files are on
Github.
This item is intended for use with DMMs capable of 4-wire measurement.
Features:
- standard 19mm space between plugs
- low thermal emf design
- gold plated quality plugs
- easy pull out with handle
- low resistance: <5mOhm between HI and LO plugs
Should be suitable for all devices with standard jacks (like Keithley 2000-Series)
NOT SUITABLE FOR DEVICES WITH:
- jacks are even / flush mount with the front panel (e.g. Fluke 8846A)
- inner contacts of the jacks are heavy recessed (e.g. Keysight 344xxA-Series)The plugs are a bit shorter than standard bananas and the pullout needs some space at the bottom.
Borderline:
Keithley DMM7510 (only small elevation of jacks from front panel)
Review from DaveDiscussionxDevsThere is a new batch international available on ebay germany - just search for "4-wire short" (include the quotation marks).

I bought one - like it. Did you consider doing one for the 3458A which has different spacing for the sockets?
Dave
Where did you source the gold plated plugs? I've been looking for those for another project

Thanks for the feedback, Dave!
I thought about
doing one for my 3457A (3458A and others should have the same spacing), but would prefere a PCB only Version.
As it turned out there is already a
design with PCB only.
But if there is enough demand for my
design idea, would think about doing it.
Where did you source the gold plated plugs?
Got the Multi-Contact SA404 22.1054 from german distributor
voelkner,
conrad has them too, but higher price - but not shure if they sell to your country.
Perhaps a search could turn out a distributor for you - if there is no option, could buy for you - send me a PM.
OK Thank you, I ordered Mark Sims' (Texaspyro) PCB version from Oshpark

I'd be interested in buying one of your 4 terminal shorts plus 8 more contacts. PM me if interested and we'll try and work something out.
MiDi, would you happen to have any of these left?
At the moment there are no more left.
But if there is a couple demand, I would do another batch.
Do you want only one or more?
Count me in if you are planning another run please.
I decided to make another batch, but it would take a couple of weeks...
They are not suitable for all devices: The plugs are a bit shorter than standard bananas and the pullout needs some space at the bottom.
If the jacks are even with the front panel or the inner contact of the jacks are heavy recessed, they are not suitable for that device!

I have a Keithley 2100 and a couple of PM2525s I can't actually recall if either of them are so will check tomorrow.

Keithley 2100 should be fine.
PM2525 I saw do not have 4 terminals and even if they would, they are of type "flush mount" and not suitable.
Not suitable:
Keysight 34470A
Borderline:
Keithley DMM7510

I was answering whilst watching TV and didn't really give it a thought. The PM2525 has 3 terminals plus the DIN socket
You'd think I would remember having 2 of them although they get much less use now!! This would really have been for the Keithley though anyway.
Started the new batch today.
It will take a couple of days to finish.
I give an update, when they are ready for shipping.
New batch is internationally awailable on ebay germany - just search for "4-wire short"!
Are they suitable for the 34401A, MiDi?
Are they suitable for the 34401A, MiDi?
Sorry, they are not suitable for the 344xxA-Series, they are to short to fit accurately into the heavily recessed jacks.
I bought one - like it. Did you consider doing one for the 3458A which has different spacing for the sockets?
This design is not suitable for the 3458A for EMF reasons. Nothing beats a copper wire as specified by Keysight for short adjustment/calibration.
Ordered; thanks very much!
They are so nice and cheap, I would so much need one of my Datrons, sadly they have the sockets on a 19x38 grid
.
If you ever make a Datron compatible lot, me and some other Datron owners will thank you and I'll buy at least one.
Cheers,

It is public domain, so feel free to fork it on github and modify it for your needs
Making them is not that complicated, you can even solder by hand.
As I made a couple, I did it with solder paste and heat gun - faster and better finish.

There is no chance in hell to look so nice like yours, offer stands

Ok, understood
I think about it, if there will be demand for min 10 pcs, if demand for min 20pcs thinking would be omitted...
Hope that was the answer you imagined

Genau
!!!
The problem is how can this be better announced, maybe a post in "Buy, Setll, Wanted", also I don't think that 19x36 grid it's really only for Datrons, there should be other DMM as well.
In any case, put me on with 2, and make them 15EUR even with a thicker copper plate.
