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
