Wanted, the Fluke DMM cap for the banana terminals, especially if you never going to use it and probably they're gathering dust in your drawer, or you're going to toss them.
My DMMs are frequently used in very dusty environment, especially in logging mode while they will stay exposed to dust for long time. Currently I use sticky tape to seal off the mA and A terminals to prevent dust getting in it. Just hate it when I lifted the tape, those sticky gunk left over + dust sticking on it, making the DMM so dirty.

Photo attached below are the example plugs came with Fluke 287 or 289, not sure at other Fluke's model.
