My meter (Fluke) has two possible inputs for measuring current. One goes up to 10A (I think) and one is fused at 100 mA. If it isn't fast enough to save the electronics, then what is it for? Why not just have one input at 10A? Radio Shack does have 500 mA fuses, so I would gladly use one if it is going to be the same.
