[time-nuts] HP Agilent 34401A

[Volker Esper]

Thank you, Bob, yes, that was my first guess, too. I opened it and 
shortened the relay contacts with an extremly low ohms short and the 
display changed significantly when coming to K101. I have to get one.

Besides, after fumbling and knocking and all that handling the 
instrument is now quite stable - that lasts till the next hyper 
important unattended long time measurement...

Thanks a lot

Volker
