[volt-nuts] Get 10K resistor calibrated in UK

[Bill Gold]

Frans:

Mine which was built in 1979, and corrected for the 1990 change in the ohm,
and calibrated last in 2009 has drifted upwards by 1.61 ppm total.  So about
0.054 ppm/year.  I don't have any data from those 30 years so this is the
beginning and end points.  These all seem to have a spectacular performance
to say the least!

Regards
Bill
