Hi all,
I've got an HP 3469B multimeter that's not behaving as it should - the
display is behaving sensibly, but the values bear little relationship
to the electrical signals applied. Nothing looks brown/smoked inside,
and it has the largest multi-gang rotary switch which could have some
dirty contacts.
Anybody know anything about the insides of these? Do
calibration/service manuals exist? I'll start tracing the circuit and
checking levels but I'd prefer some intelligence before going in blind.
Thanks,
Michael
