Disconnect without removing?

That's worked for me in the past at Sports contests. I removed the
vacuum power source (a retractable venturi), and tagged the face of
the instrument INOP. A couple times I checked with the CD, and that
was fine with them, but usually I just figured that anyone who didn't
like it could file a protest and I'd address the issue if I had to.
Never happened.

Thanks, Bob K.
