What happens when a fuse is blown on a meter?

If the reading is close to the one you got when you touched the positive and negative leads, the fuse is fine. If the fuse is blown, the meter will not read anything at all, or the meter may say “Open Loop” or “OL.” If you want to use the meter as an ammeter, keep reading! Did this summary help you?
