Re: [Phys-L] ceramic fuses

Fluke is a brand that can always be trusted.
(With a name like that - ya GOTTA be good ! ! !)

Extech is cheaper, I'll wager. (and for a reason!!!)

I am pretty sure that the problem with the Extech meter was that the
fuse was rated very close to the maximum displayable current. And as
the fuse got warm, its resistance changed. The resistance of the meter
*definitely* changed significantly with current (on the same scale!).
This did not happen with a Fluke meter that I tried.

Regarding my discussion, the meter manufacturer never explained the
problem I was seeing.
