I busted my multimeter due to improper use (see Why would a multimeter give an unexpected current reading?) and so decided to change the fuse. Annoyingly I can’t seem to find a 15A 1000V 6.3mm x 32mm fuse, and the closest thing I can find is a 15A 250VAC fuse. I was going to go ahead and assume yes, since I’m only ever going to test DC voltages around 24V or below (but you never know, I may use it to test up to 230VAC in future), but I thought I’d check with the experts before happening upon another silly mistake. The multimeter is an Owon OW18E.
Also, curiously, the rating on the front says 20A.
Also, is it likely that a 1000V 15A 6.3mm x 32mm fuse can be purchased in the UK? I've checked all the usuals in the UK (Farnell, RS, etc), but the highest rated seems to be 250V at 15A. Alternatively, I found a 600V at 10A, but so far nothing near 1000V 15A.
