Either the meter was set on current (amps) which would indeed produce arcy sparky shows and endanger the meter or blow a fuse, or the one probe was indeed touching two things when you were trying to take a reading. Given how crowded and awkward it is inside the control area, it is pretty easy to do. You can always tape up all but the very tip of the probe if concerned.
