Here is the simple answer. If you wrongly try to measure volts while the meter is setup to measure current (amps), you create a short circuit. Short circuits melt or fry things, like the meter. The meter companies put a fuse inside to protect the meter from this damage while it is set to measure amps. If you never misuse the meter in this way, the fuse will likely never blow.

It is very easy to make the mistake of leaving the meter set for amps when you go to measure volts. When you do, the fuse will likely blow and then the amps setting will no longer work until you replace the fuse.
