Which leads me to a second point:

My Fluke 37 has two fuses on the low current range. A cheap-ass 600mA fuse and a big expernsive 2A HRC fuse.

It seems like an awesome idea to me. I wonder why it was discontinued. You could even have the cheap fuse accessible from the outside for user serviceability.

(my understanding is that Fluke, etc., deliberately make maters that you have to disassemble to change the fuse so that corporate types can seal them up and know which meters have had their fuses blown)

I think that is obvious:  removing 12 $ fuse is 12 $ more profit for Fluke. They are not in business of making dream meters, but making money...

Oh great, thanks.

I would love to see Joe Smith put a Fluke 25 / 27 through it's paces, I think the closest he has come is the Fluke 77, but that used spark gaps rather than 5 MOVs. Even then, he does not have the capability to test high current fault clearing. It would probably be one for Photoinduction! :scared: Comprehensive testing would require a large pile of expensive fuses anyway.

This may be the only statement I read on the internet today that is true!!   :-DD    20J or even 600J is nothing.  Photonicinduction with his cap bank would be closer.  Best to let the pro's run these tests:

Maybe they learned that once the non-safety fuse came apart it started a reaction that could not be stopped.  I could see it (expanding plasma) bypassing the safety fuse all together.   It seems like a stupid idea to me.

Small, cheap HRC fuses exist. A meter can be designed so that the small fuse can't create a chain reaction.
