Kontron Computing Multimeter DMM 4040 Manual ?

[shempe]

Long time ago, I bought this DMM and since then, I am searching for a manual or better a service manual.



I phoned around in Germany but no luck so far.
I searched the usual shops for a manual also no luck.

Maybe someone can help me out.

Guard terminal? External reference option? This is interesting meter. Open it up and let's see how it works

I think it is nothing special on this Meter, but who knows without manual or spec´s?

Here we go, a quick peek inside.

Analog Board.


Digital Board.


Back Side.

Is that a Caddock network near the bottom left on the analog board? These layouts are so dense, I can't pick out the reference.

Yep it is a Caddock.

and here, I think the Ref +  4 1/2 A/D



4 1/2 A/D for a 5 1/2 Meter ??

Hi,

did you make any progress the last years? I have stumbled across a defectiv DMM4040 recently and now I'm looking for schematics etc. but there seems to be nothing available.

best regards, Hermann
