Siemens Voltage Calibrator D2300

[Spikee]

So i got this unit from German ebay and it is awesome !

Known specs:
0-1000V (positive or negative)
2 or 4 wire
Current limiting 30% 50% 100%

- 1V 100mA max
- 10V  100mA max
- 100V 10mA max
- 1000V 1mA max

Picture of the unit doing 0.999 99 V (not warmed up) 4-Wire :

Anyone know more about this machine ? 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.

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.

on Sunday evening i will go back to my dorm an i will take the top off to look whats inside.
Would love to go to a calibration lab to test what this puppy can do! To bad that's out of my reach  .

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

To bad your device failed. i tested mine on the 1000v range and it worked fine.
Did you find more info about the machine?

Looks impressive enough.
Would love to know the accuracy and drift specs and see how it compares with say my MV106

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.
