Do you really have to start a new thread every time you mention this (7075) DMM?

Kleinstein provided you with an informed response here...   https://www.eevblog.com/forum/metrology/solartron-7075-413074/

From your thread on UK Vintage radio, you seem to be asking for somebody to read the manual for you because you "don't fancy trawling thru 200+ pages of the service manual to find out".

You need to read and thoroughly digest the manual if you're going to stand any chance of fixing it!

Dont give up your day job!.

If the OP hasn't got time to read the & manual, block diagram & circuit diagrams, we certainly haven't.

Not only is it a near-duplicate post, he hasn't even got time to put the model number in the title, nor to have conventional capital letters and punctuation.

In the days of snail-mail, his missives would be handwritten in green ink.

Definitely a timewaster.

Here's that post: https://www.vintage-radio.net/forum/showpost.php?p=1613791&postcount=4 At least he managed to put "7075" in the title over there.

"Paul Larner of Northampton" is pissing people off over there, too. Reminds me of another irritation: f*/t*/o*

[factory]

I can't remember if he did get the title correct on the radio forum, as the mods usually correct them or add missing info, note only the mods can edit titles after posting there.
 
Oddly his location is different on here.

There's a reason for that

Reason for pissing people off is easy to understand. But is your response also about why we are reminded of that other nuisance? Are you implying the two posters are correlated?

The second one (Dave confirmed it a few months back).


Edit: Oh, sorry, you meant treez. No, m3vuv (I thought you were meaning the lower case, no punctuation).

[factory]

I've thought this is the same as user as the banned "m3vuv" (aka "M3VUV51" on the radio forum, who was banned too) for a while, think the a bit of google confirms my suspicions.

Anyone able to look up the QRZ call-sign list to confirm?

Bloody hell. This is the post: https://www.eevblog.com/forum/projects/chinese-electronic-load/msg5132787/#msg5132787

I'm becoming seriously irritated by some of the posting behaviour on this forum. I perfectly understand why the mods let many things pass until members bring their attention to such behaviour; rational, proportionate, etc. But if there are too many "broken windows in the neighbourhood", people start to move out because of the deterioration.

[factory]

Trouble is it can be hard to tell (apart from the illegible posts in this case), when banned people return under new names and at least three different locations.

You can't escape anywhere on the web, see post #137 here; https://groups.io/g/Solartron_Schlumberger_Equipment/topic/input_connector_cable/103448605?p=,,,20,0,0,0::recentpostdate/sticky,,,20,0,0,103448605,previd%3D1706264012417121716,nextid%3D1596896352824358660&previd=1706264012417121716&nextid=1596896352824358660

I rest my case...

yeah  become a pleague here in some cases, even reporting similarities to the mods, does not end in locking the offending thread(s)   for sure  when you see it the same section 3x  almost identicals titles / descriptions about the same thing  pffff   

lost some faith here

and i do think  some  whant to see their count postings goes up ?

Gurgling for "m3vuv" leads to...

Public access gives a photo of a person at South Queensferry and some person's biographical details. I have no opinion of veracity of this, and no way of verifying it, nor whether it relates to this thread's OP. Make what you will of that public information.

Searcbing this forum for "quadzillatech" is also interesting.

[factory]

Interesting, but as you say doesn't relate it to the OP here, but the post on the Solartron groups.io about input connector, dated around when this was DVM was purchased is from a member with the username of "Paul M3VUV", or maybe someone joined to troll using his name IDK.   

The Quadzillatech (bet there are more alias we haven't spotted) posts made very interesting reading, especially the scamming on ebay one.  Makes me question if I want to continue selling on there, I will definitely be avoiding buying any Solartron 7075 DVMs with banana sockets.

See the HP groups.io too; https://groups.io/g/HP-Agilent-Keysight-equipment/message/120903

P.S. almost forgot the this thread, the radio forum & mods got attacked; https://www.vintage-radio.net/forum/showthread.php?t=185578
