The voltage level is straightforward. Do not use a meter/probes rated less than the voltage of the equipment being tested. The meter/probes can explode and cause an arc flash.

How do you check if a fuse is blown with a multimeter?

Place the multimeter on the ohmmeter setting and place the probe leads across the 2 ends of the fuse. If the reading you get is very low, a few ohms, then the fuse is continuous and, thus, good. If the reading is get is very high, such as severeal Megohms, the fuse is broken and, thus, bad, and should be replaced.
