Fluke 123 continuity buzzer

[melovelo]

Fluke 123 scopemeter when set to continuity will sound buzzer intermittently without test probe and common probe touching. I can’t see why so any ideas please.

There's a fair chance of some contaminent or foreign object down in the jacks or on the pcb. Give it a careful clean with IPA and dry it thoroughly and see if that helps.
