Default Re: Small DMM fuses

Not sure I like those fuses, they don't offer much protection to you or your meter. I see there are no PTC's (unless their on the other side) or spark gaps, just those big 5M R's. If it were mine I'd be tempted to replace the fuse holders to accept a normal 3/4" fuse, It looks like there's room to move one post back behind those black screws.

I'd be wary of using your DMM on the mains, is it CAT rated at all? Lastly if you get a chance and a spare £30 try and get a Fluke 25, they have proper protection and survive numpty's trying to measure 600v while on the ohms range. After buying a few meter's and killing them it was the best thing I did. They don't measure capcitance but you can test caps with the DC resistance with a bit of experience.

Sorry for the hard sell on the Fluke, there is a good reason though, why a lot of folk swear by them. They accept standard fuses for one.
