The stability is not high enough to be useful!
Have a look to http://www.on4jln.be/infos/getfile?file=515A-OM.pdf,
it is the Fluke 515A, to learn how they dealt with that problem. If your 10V
is good you will get better results too. And it needs to be very good to calibrate
the 7081! Stability is more important than everything else and that is the problem.

Have a good day.

Bye,
Jean-Louis
