To avoid blowing a fuse, destroying the multimeter, or risking injury, do not attempt to test current higher than the maximum allowed for your unit. Among other things, multimeters can determine: ...

Switch the multimeter to measure resistance at its lowest setting, and test across the fuse. A reading of OL, or significantly higher than 20 ohms, suggests the fuse is blown.

You can use them to test for voltage drop at various circuits, blown fuses, current draws, heating elements, and to verify bad cable connections. The most common task is checking pedestal voltage.
