Hope you don't mind me jumping on this thread and asking a basic question: is
there any kind of procedure for the 'enthusiast' (say with single 3458A/single
732 and not say 4x732) to measure the drift of a

Betreff: [volt-nuts] 732A drift
I hope someone can help with a strange anomaly on either my 3458A or the
732A. The 732A 10V output as measured on my 3458A seems relatively stable
over time
Randy,
I looked at the 3458a input impedance, and it is difficult to get the meter set
to the FixedZ (10M) mode. However, the 100v range is 10M. It should default to
HiZ on reset.
I forgot to mention to check the outputs and guard resistance to ground. One of
my 732a had some foam baffling
luck.

The output impedance of both the 1v outputs is ~1k ohm. I wonder
I hope someone can help with a strange anomaly on either my 3458A or the
732A. The 732A 10V output as measured on my 3458A seems relatively stable
over time (it bounces around about +/-1 uV but is it the 732 or the 3458?).
However, the 1.000 VDC output drifts downward at a rate around 1-2 uV per
