Note that most DMM are usually rated for 1kV CM. You could look for the littlefuse FLU.44 they might be compatible. (sorry the ar. link) Good thing your DMM is still pretty useful in the meanwhile.mattamatta said:I'm part of the 0.2%!
Only time I've ever seen one blow was trying to measure the test current of a hipot tester. "It's basically floating and the 1.5kV is all common mode, I'm sure the meter will be fine", I said... not so much. I guess that's one reason that they put a fuse there!

i have second DMM, same exact model, needs fuse too on mA(400mA), but
i will install 200mA rated fast blow fuse from tubedepot, instead $35 / 400mA...
10A socket measures mA pretty accurately... no idea, why even bothered buying that expensive fuse!
joaquins said:I work on big industrial connections capable of 10s KA short circuits, it's a lot of energy to be released in my hand if I screw my chopsticking, expensive fuses account for that, and provide no flying glass across myself, cheap fuses doesn't. That's why special DMM fuses are expensive.
