I have a GB Instruments multimeter (GMT -19A). I've had this meter for years and it's always worked fine.
It came with 2 fuses. One was installed in the fuse holder inside by the batteries. The other is a spare fuse which was in a plastic clip on the other side of the batteries, and meant to be a spare.
The fuses are 7/8 inch long and are supposed to be SFE 0.5 amp / 250V.
I have gone to several hardware stores, an automotive parts store, and a home improvement center. No one carries this amperage fuse, at least not in that length (SFE). I thought I'd use a 1 amp if nothing else, but I cant even find those.
For now, I found a 9 amp that fits, and am using that, but I know that is not going to protect the meter.
I dont buy much online, and only use Ebay when I do. I thought Ebay surely would have them, but I was wrong. Ebay has SFE fuses, but only in larger amp sizes. Seems 7.5 amp and higher are common.
(I searched ebay using these words "sfe 1 amp fuse" )
- Now I know why I miss Radio Shack, they usually had stuff like this.
Does anyone know where I might find these fuses? (Even a 1 amp size).
No, I am NOT willing to go to one of those places that have a large minimum order, or charge $10 or more to ship a small item like this. After all, multimeters like this only cost around $25.
One thing I did find, is at a local hardware store they do have a few boxes of AGA 1 amp. Those are a little short though, but I was wondering about slipping a tiny piece of copper tubing over one end....
Without having one of them in front of me, I am not sure what the actual length is for a AGA type. But a website lists them as 5/8" so I assume that's correct. I also learned that the AG means "ALL GLASS".
[ I do wonder if I might still find these using other wording, on ebay. I really would expect Ebay to have this... ] But what wording???
