content: While I believe this unit is functional, it's sold as spares / repair because I haven't tried all measurement ranges. It certainly works with a 34901A card, measuring resistance etc on multiple channels. The rear plastic panel is missing, looks like it got damaged somehow. Display excellent, bright and clear. Knob and buttons fine.Edit: The CR14250 lithium backup battery (for RTC, state storage) needs replacing, but the unit functions without it.£75 inc delivery to UK mainland address. No cards or cables.£140 inc delivery to UK mainland address with a 34901A scan card included. No cables.

content: Yeah, that was a good deal indeed, congrats (and thank you) to whoever bought it - I'm not sure I would've been able to resist :-)One of my units is also missing the rear bessel and I've seen EBAY ads where it's also missing. I wonder if it perhaps has to be removed in order to rackmount the unit.EDIT: Although, you don't have to knock it of with a hammer :-)

content: I've thought about drawing one up in CAD and print it, but yeah, someone else seems to have done a great job already.https://www.thingiverse.com/thing:6159453I will print one this weekend and see how it looks/fits. Thanks!

content: Quote from: H.O on June 26, 2025, 04:52:57 amI just removed the rear bumper from my 53181A and noticed that it can catch on the rear bezzel quite vigorously at the corners. If there is a weakness around the screehole in the 34970A design of the bezzel, I can see how removing the rear bumper incautiously breaks it in the way that's indicated by the residue.

content: Allright, printed one. Fits nicely except the design has sort of a lip around the corner where the IEC input socket is and it interfered with the socket on my unit so I had to cut it off, couldn't be bothered modifying the part and reprint.

content: Quote from: H.O on June 28, 2025, 07:46:16 amMaybe that was intended as the extra support to hold the iec socket in place, like the metal bracket that normally surrounds it (see picture in OP).

content: Ah, that's probably it.None of my units have that bracket and I didn't notice it in your photo. On a parts donor I have the IEC socket is indeed loose so that bracket might have been an afterthought to rectify that. It's possible that the IEC socket on my unit has been replaced at some point, I don't know. Either way, the lip had to go in my case.

content: AFAIK the lip on the moulding was a modification to fix an issue where the mains inlet could come unclipped and potentially expose live terminals. There was an HP note or something about that. It looks like the metal bracket is another fix for the same issueOne of my (second hand) 34970A’s arrived with a broken rear moulding. It had failed at one of the screw attachment points. I fixed it my fabricating an aluminium reinforcement piece, with a hole for the screw, that just fit inside the recess surrounding the hole. It is fixed in place with epoxy resin, and I have had no problems since.Note that you don’t need to take the rear moulding off to remove the rubber bumper.

content: I've never noticed this retaining bracket for the IEC power inlet, and I have 4 of these units... very interesting.
