Burster MIKROMAT Kompensator 9303, mV Standard?

[HighVoltage]

This Burster MIKROMAT Kompensator 9303 was a bargain but I can not find anything about this standard? It seems to be a DC mV standard reference.

I can only find info's to a similar device, the "Burster Mikromat 3401 DC-Standard".

Has anyone here seen such Model 9303?
Maybe someone has a user manual?

Try sending Burster a email?
They were very responsive when I asked about my Digistant 6425T.

Yes, I have done that already and they replied that this instrument is not known to Burster.
They asked for pictures, LOL
Maybe they still find something.

All switches were stuck from bad grease and some contacts slightly dirty.
After cleaning and greasing it seems to work well.
Here is a first test.

Maybe forum member "branadic" has more info...

BTW, it looks like a more simple version of the Burster Digistant:
