For few euros I got this portable calibrator:
*Thommen multifunction calibrator Model 230*
see pictures at:

I was able to test it on the output voltage mode and it seems rather precise
(tested with a Solartron 7150+)
Unfortunately I wasn't able to find any info on its usage in the other
different modes (current/resistance/...).
I tried to contact Thommen AG but with no avail...

Do someone of you have more info/manuals/... about this calibrator?
