What ohmmeter reading indicates that a fuse is good and no further testing is necessary?

A reading of zero on an ohmmeter indicates that a fuse is good and conducting electricity properly. This means there is continuity through the fuse, and it has not blown or created an open circuit. When a fuse is functioning correctly, it allows electrical current to flow freely, which the ohmmeter detects by showing a near-zero resistance value.

In contrast, other readings like infinity would suggest that there is an open circuit, meaning the fuse is blown and not allowing current to flow. A reading of one thousand or five would imply some level of resistance, indicating that the fuse might not be functioning properly, and additional testing would be needed. Thus, a zero reading is the definitive indication that the fuse is operational and no further testing is required.
