thank you very much for the schematics and the photographs!
Using XP / firefox, I was able to retrieve the files with the given 
special link, and also very easily with the FileZilla Client.

The most interesting part, i.e. the precision resistor circuitry, 
obviously resides on the bottom side of the ref board.

Would be great to get a photo also from that side, as Datron made some 
efforts to get rid of strain and heat conduction effects.

Best regards - Frank Stellmach
