The continuity reading on a functional fuse will be:

A continuity reading on a functional fuse measures the ability of the fuse to conduct electricity without interruption. When a fuse is intact and functioning properly, it should have a continuity reading of 0 ohms. This indicates that there is no resistance in the path, allowing current to flow freely through the fuse.

In practical terms, this means that when you measure across the terminals of a functional fuse with a multimeter, you get a reading close to 0 ohms, confirming that the fuse is not blown and is ready to protect the circuit from overcurrent conditions. An infinite ohm reading would indicate a break in the circuit, meaning the fuse is blown and not allowing any current to pass through, while the other ranges of resistance values would imply some form of fault or improper functioning of the fuse. Therefore, a reading of 0 ohms is definitive of a good, operational fuse.
