AVO 8 4mm sockets
Any one know if it's possible to get sockets for the Avo 8 that will take shrouded 4mm plugs? OR to get test leads with right-angled, unshrouded sockets? I'd like to get some right-angled 4mm plugs + leads for my Avo 8, but looking at the CPC catalogue I can't see any without shrouding.

Re: AVO 8 4mm sockets
Cut the shroud off with a Stanley knife?

Re: AVO 8 4mm sockets
For safety, I buy the retractable shroud leads from CPC, made by Hirschmann.

Re: AVO 8 4mm sockets
"Cut the shroud off with a Stanley knife? "
Thanks Paul. After my original post, I also wondered if that would be the easiest solution. But I do like the idea of shrouded plugs - after making difficult connection to a component, you might want to transfer measurement to another instrument (such as a scope) without disconnecting the component ends of the leads - possibly leaving the plugs wandering around workbench and looking for an "interesting" home for a moment. Unusual circumstance I know, but it happens.. Seems odd that straight unshrouded plugs are easily available, but not apparently right-angled ones.

Re: AVO 8 4mm sockets
"retractable shroud leads"
Thanks Sinewave, sounds like perfect solution. But I've just looked at CPC catalogue, and can't find any leads mentioning retractable shrouds. Can you point me in right direction? Thanks Mike |

Re: AVO 8 4mm sockets
You can get adapters that are effectively a 4mm socket (which is designed so a shrouded plug will fit) to 4mm plug (unshrouded).
For example, from RS : a 'plain' one : https://uk.rs-online.com/web/p/test-...pters/1222780/ one that can be locked in place by an allen setscrew at the bottom of the socket : https://uk.rs-online.com/web/p/test-...pters/5071029/ another type : https://uk.rs-online.com/web/p/test-...pters/7260647/ Not cheap, but probably worth it if working on high voltage stuff. |

Re: AVO 8 4mm sockets
Thanks Sinewave and Tony. They look useful, but the essence of what I want is right angled and unshrouded. My workspace has to double as a workbench and as a proofing & editing desk, so the Avo (and other testgear) normally lives in it's leather case on the floor, being brought up occasionally for use as necessary. I use it in it's leather flap-top case, so its useful to be able to leave the probe leads in the terminals for quick use. I could close the case flap with right-angled leads in place, but straight ones stop it closing, so I have to unplug them to put meter away and then fish around for them in the leads compartment when I next use it. Sorry - tortuous explanation! I'm just puzzled as to why a simple thing like an unshrouded right-angled plug seems impossible to get. Perhaps I'll have to go with the suggestion of just cutting off the shrouds.

Re: AVO 8 4mm sockets
Why not use these as adapters - they are 'right angled' as they don't stand up from the meter. Available from CPC and others.

A point to note with those is that shrouded plugs will fit these terminal adaptors. https://cpc.farnell.com/tenma/76-079...red/dp/IN07822 https://cpc.farnell.com/tenma/76-078...-me-pd-mi-alte

Re: AVO 8 4mm sockets
Thanks for those tips. Why didn't I think of the spade adaptors? Genius idea! That's probably the way to go - and will give an even lower profile than angled plugs. I'm a bit puzzled by the maximums rating however - CATIII-1000V, yet the voltage rating is only 30V AC/70V DC. Not sure how that works out.

Re: AVO 8 4mm sockets
I've tried the spade adaptors, and decided they are too cumbersome and cluttering. The spade bits don't fit the Avo sockets well. Thought I'd try cutting off the shrouds, and that gives a very good and much neater fit, with no bare metal left exposed. I'm happy to bear the very slight risk of fingers contacting plugs on insertion and removal - after all, we all lived happily with that for many decades until very recently...

Re: AVO 8 4mm sockets
One of my AVO 8's, ex-BBC Rampisham, is fitted with shrouded sockets (purists look away now, please). It works a treat and was modified to save using those protruding terminal appendages that one secures with an internal grub-screw.
