Doesn't the Fluke 117 have input jack alert? If it doesn't then it should be kept away from mains AC.
Me? I think the only "electricians meter" made by Fluke is the 113.

No, I can't see input jack alert in the specs (Unless I missed it). It just has things like Lo-Z volts to avoid ghost voltages, non contact volts (insufficient for safe isolation), Auto AC/DC volts (useful, checking an AC circuit on DC range is another accident just waiting to happen!). But certainly too many gotchas to consider it anywhere near intrinsically safe (for anything other than not blowing up in your face). Basically, it still relies on you not being an idiot... every single day.
Edit: Yes, the 113 (+ Proving unit!) is better.

Nobody has answer for why brand new meters have blown fuse. I don't either except perhaps those are not brand new.

That's called learning the hard way ... and paying to put a new fuse
And now: process your setup mentally before doing any measurements to avoid this mistake again ...

I never saw this in many brand new meters i have bought : Mastech, Fluke, Beckman, Amprobe, bench or portable ... and all the old stuff i've bought ...
The @OP must be incredibly unlucky ... ?

Moral: Never ever put your meter away with the leads in the amps connector. Always move the leads back to the volts socket when you've finished measuring amps.
(and get a meter with jack alert... I think all Brymens have it)
