Up and Coming 6½ Digit bench meters in 2016 or Go for a Keysight 34401A ?

[Dr. Frank]

By spying on the serial numbers, one can figure out the number of units sold.
The serial numbers always run from #151 continuously upwards, therefore:

34461A: 17074 units, ~4/2013 - 12/15, ~18.9M$
34465A: 2394 units, 11/2014 - 1/16, ~ 3.4M$
34470A: 512 units, 11/2014 - 12/15, ~1.5M$

I think, this latest DMM platform from agilent/Keysight is quite successful.

Received my 34461A today - my first new in box Keysight product! Its calibration is 7 months old, came from factory with version 2.08 so it has the proper calibration date stored. I would have been turned off by the calibration date but I knew about it before hand. Slightly older stock meant that it was purchased by the dealer when the CAD to US dollar was better. As a result I got it for several hundred less then it is currently at tequipment. And it is new enough to have the updated front panel silkscreening which I wanted.
I guess its time to measure everything I have here now...

Congratulations on your purchase. You will love it, I have no doubt, especially the graphing / trend chart function.

Same here, I just finished moments ago, demonstrating resistance drift and logging with Matlab , this thing is incredible, there is no way I can afford a second one.

I would recommend diligence over greed any time.

I've been making histrograms of the various Agilent power supplies I have showing the drifting as they warm up.
I haven't tried taking it apart yet but don't see a calibration void sticker on the casing, yet my 34450A has one(from Keysight directly).
