I recently acquired an HP 3457A. The instrument seems to work, but I
get error "9 NOT CAL'D" when switching to ohm and freq functions and
on completion of the self test, even though it says "SELF TEST OK". I
do not get any HW errors and the cal ram seems to be working. Anybody
have any ideas what could be causing this? Any info on error codes
and the DIAGNOST and TEST commands would be greatly appreciated as I
don't have any manuals.

Best Regards,
