How to use a multimeter to check if a fuse is broken?

1. Whether it is AC or DC, first switch the multimeter to the corresponding voltage position, first check the voltage of the pile heads on the two fuses, if normal, it means there is no problem with the power supply, and then check the voltage of the pile heads on the two fuses. If the voltage is the same as the upper pile head, there is no problem with the fuse. If the lower pile head detects no voltage, it can be concluded that one fuse is burned or both fuses are burned.
