How do I know if my multimeter fuse is blown?

If you try to measure the current with a blown fuse, you'll probably notice that the meter reads '0.00' and that the system doesn't turn on like it should when you attach the multimeter. This is because the internal fuse is broken and acts as a broken wire or open.

How do you tell if my multimeter is broken?

If it's very low (close to 0 ohms), it's still good. If it's very high (open circuit), it's blown. A 200 mA fuse should have a very fine wire visible inside the glass. If it's completely clear, the wire is gone (blown).
