(Old) Hioki 7010 DC Signal Source - Any information? Schematics?

[kblue]

Hello there!

Found this "little" thing and its a bit "off-spec". For example 5.000 V Output is reported as 5.012 +/- V. Tested with different Meters. So far no luck with any useful information. However, i was able to find some pictures with similar looking units with up to 10 VDC output (my one stops at 8.000 V for V-DC and 80.00 mA-DC) at japanese auction sites. Mayhaps someone here has more informations available? It does look like a rather nicely made unit and it would be nice to check some simple meters


Best wishes from germany!
