If you leave your 34401A on 10G input with nothing connected in
a dry atmosphere, it is going to build up charge and trigger the
autorange relay.  Anti-wear-out mechanisms are certainly relevant.

A similar mechnism is documented in one of the 3458A manuals.

Never attribute to malice what can adequately be explained by incompetence.
