Jorgen,
I have an original manual for the HP 3440A voltmeter, which is the same
as the 3449 except for the sample rate, cost U$S 12.00 plus shipping.
Let me know if interested.
Thank you.

Hello All
I was just given an old HP 3439A Digital Voltmeter to play with.
It has the 3443 High Gain/Auto Range plugin. The Nixie tubes
light but display random digits. I have searched for a schematic
and found nothing. Really, like others have said here before, its
the challenge to see if I can get it functioning, so any info about
it is appreciated.
Thanks

Did you check all supply voltages for ripple?
Power Supplys has to be checked first, ever!
