[volt-nuts] Best reference after LTZ1000

[Marvin E. Gozum]

Hello WarrenS,

Time for me to leave for the night, but the image/graph came through, 
and it is AWESOME!
This is what's needed.  More later, thanks a ton.

Also the point you emphasize is vital, voltage references are not 
identical, some are more stable that others even within the same 
model line.  Aging and grading is a key function, and very hands on, 
which being labor extensive, translated to expen$ive, as we see in 
the HP 3458a high precision option board.
