The previous owner did not have the manual. I searched on the internet but there is not a lot to be found. Would love to know the real specs!Also does anyone know what the Objektstand sticker (1) means ? or the Gepruft H126 sticker ?Sticker 2 shows Ausgabe , is that like the build year ?I will tear it down after the weekend when i'm back at my dorm.

content: Very nice find, I love the old Siemens gear."Geprüft" simply means "tested". Good thing, somebody somwhere has tested this thing."Objektstand" your guess is as good as mine. It could be a revision number or something of that sort.It could also have something to do with a companies inventory or a thousand other things.I'm not sure how to translate that because I don't know what they meant by it."Ausgabe" this could be translated as "issue". So this could also be a revision number or similar.It was absolutely certainly not built in 2005. Not even in 1995. I'd date it to the early/mid 80ies at best. I wouldn't be too surprised if it was even older.AFAIK Siemens stopped producing T&M gear sometime in the 80ies or early 90ies.Would you mind taking the top off so we can have a peek inside, please? Then we'll be able to date it. I bet it's full with Siemens made IC's and caps. They made very nice bright orange electrolytics back then and they were always stamped with a datecode.EDIT:I can tell you it was probably serviced after 1993, back in '93 Germany changed postal codes from 4 to 5 digits, we had to after taking back the GDR.

content: I've got one, too. I recieved my unit half-broken. The HV Option (100V, 1000V) caused the whole device to fail when installed. Some relays were stuck and some caps had gone bad. I've posted some pics here:http://www.mikrocontroller.net/topic/263461#2741110

content: Looks impressive enough.Would love to know the accuracy and drift specs and see how it compares with say my MV106Dave.

content: Considering Siemens crazy way to name things (Boost converter=Hochsetzsteller, which convolutedly means "Level-increasing adjustor/regulator") "Objektstand" (object status, object position) most probably means Revision level.
