I am trying to replace the burned out fuse in my multimeter. It is very small with dimensions of 3.6mm X 10.25mm and has a rating of 600mA @ 250V. I can't seem to find this fuse. I can find one with the same dimensions but it has a 1A rating and much larger ones with the same ratings. Is there any reason why I shouldn't use a larger(physically) fuse in my multimeter? I'd have to make some modifications to the multimeter to accept it of course...(I'd only ever be using this multimeter for low power applications).

the fuse itself spot for the fuse

    \$\begingroup\$ You've already blown one fuse which indicates that you are error prone and need protection. Putting a higher rated fuse in is a bad idea. Putting a physically larger fuse in will compromise safety clearance. I'd recommend getting the right fuse. \$\endgroup\$

    \$\begingroup\$ The fuse is there to prevent fire. Replace it only with equivalent or faster fuses. \$\endgroup\$

  • \$\begingroup\$ Do you have an image of the old fuse, or can you provide the markings on it? \$\endgroup\$

  • \$\begingroup\$ ive added a couple of images. not sure if they'll be of any help. I would say i am reasonably error prone as any beginner is yes but as i stated i wont be working on high voltage projects. i really just wanted to know whether there was any different in the way the fuse operated because if there isnt then it should work in my multimeter after i modify it. \$\endgroup\$

  • \$\begingroup\$ the blob on the end of the fuse indicates that the fuse wire is soldered in .... just break a 600mA glass fuse and use the fuse wire to replace the blown one .... i have done this before and it works .... otherwiese, install an inline fuse holder, if there is room \$\endgroup\$
