The second device which showed up on saturday is the Fluke 732A which I stumbled over by chance on Thursday evening.
It is now online for about five hours and the thermistor inside of the oven stabilized at 3475.4 Ohms.
It started around 13kOhm. The output itself looks very clean and now stable at 10.000184V.
Will monitor this further.
I did not open the case of the 732A, first I'll do some readings and looking for the manual.
I think TiN has a copy on xdevs.
Here are some pictures:
Front side, the binding posts. Look at the different colours of the metal inside.
I think, the red ones are the CuTe ones and the yellow-ish ones are brass.
It has sticker all over it and by the looks of it it was used by the air force of the Bundeswehr (German Army).

The "ID-card" of this thing:
"Do not remove seal"
Inventory number
electrical checkup was ok in 2015 and since then the unit wasn't opened.
The batteries were changed in 2014 and last tested in 2015
low voltage power input:
Is this some kind of Lemo connector? Does anybody know?
Last calibration July, 27th 2015
Next calibration: July 2016 (which didn't happen, I think)
Online for around 120min:
Up now for around 5h
Screenshot from the DMM7510:
Will check what it is doing tomorrow. And I'm curious how the batteries behave.
The LED for the battery charging shines but I suspect, that the batteries are dead after this long time offline.
Will keep you updated.
