#1434 clocking in. 20 higher in build number than LazyJack's and on the other side of the planet  :)

So far after an initial tweak sitting very stably on my 34401a within a last digit on 6 1/2. micro volt had a small 3-4 microvolt offset to chase up other than that put the lid on and use it  8)

Interesting looking at how low the production numbers were over 4 years too.

Apart from being sensitive to input loading this looks like being one of the most boring bits of test gear I own  8)

Min/Max Variation of 0.000001 Vdc with a 10+ degree temperature swing over 24 hours.

Mmmm now is the drift of the meter and reference excellent or are the reference and the meter just drifting together and really really terrible .....   :scared:

You need more DMM (and perhaps more references) to verify that.  >:D

I have rack space available for the 3458a and a few LTZ's waiting for Vishay goodness ;D

These must be reasonably rare on fleabay. I didn't know they existed... would be a cool addition.
