Hi!
I sold on eBay about 3 years ago a Metrix OX 8627 (analogue/digital CRT based) oscilloscope with a number of faults because Chauvin Arnoux (the lot that took over Metrix) refused to supply me with a service manual and quoted me over 400 € plus shipping costs (both ways!!!!) to send it somewhere in France to look at it!
I found a post from somebody who claimed to have schematics for this on another forum but when I contacted him he just ignored me – I knew he must have got documents of some sort from somewhere as he quoted circuit reference nos. in his post, and those oscilloscopes are totally devoid of silkscreen on any of the PCBs anywhere!
Have C.A. always had this policy of refusing technical help and support or was it a policy change of theirs fairly recently?
(If I could have afforded this I'd have paid then kicked up a nasty stink with C.A. afterwards stating the repairs hadn't been done to my satisfaction and insisted on a refund or a copy of the S.M. – in short – paid under duress and then make their life a misery afterwards!)

PS!
I never got to hear anything back from the buyer, by the way, so I've no idea whether the faults on that oscilloscope got fixed or not!

I know of someone on here who has successfully been in touch with C.A. in the past few years and obtained DMM schematics that he was kind enough to share here.
I asked them for help once over, they redirected me to https://www.manumesure.com/ (https://www.manumesure.com/) for the technical aspects. I don't think I took it any further.
To me C.A. are going down the drain, you even have to login to their website to download free software now, other T.E. manufacturers do that too, I can't see the point.
When you do find schematics from the Metrix era never take them for granted, they aren't always that clear and I've spotted a couple of inconsistencies on the previously mentioned DMM schematics.
For the OX 8627 if still of interest, it should have at least some PCB's in common with other models from the OX800 family if schematics for those are around the www.
There are some schematics to be found here for a OX 8627 scope that apparently had PSU and CH1 problems:
