[volt-nuts] Pickering Patent

[Frank Stellmach]

Hi John,

the "degaussing" technique by Pickering (for former Metron Corp.) is 
used in the Fluke 7000 reference, which is based on the LTZ1000.

This would be an interesting volt-nuts project, to add an degausser 
circuitry, as it seems that it can be realized easily.

On the other hand, I did not find hysteresis effects on a 1ppm level yet 
on my 2 (3) LTZ1000 references, although my dearest wife has cut off the 
supply of my double LTZ standard for a few days to save energy.
Until then, the box had been running for about 2 years without 
interruption, and they had been and still are in agreement with the 
3458A and the 5442A to the mentioned stability level.
