Whether you own a performance sports car or a motorcycle, an ammeter can be a very handy gauge to have. This tool will help you determine whether or not your alternator and battery are working in harmony. These meters are used in many cars where there are multiple pieces of equipment that are dependent on the battery. Although some cars come with a very simple ammeter already installed, for those that make additions to their car or motorcycle, it is recommended that you wire up a more professional style of the meter to ensure that everything is functioning properly and your battery is staying charged. For some components, it is very important that they do not lose power, as items that incorporate the use of computers may reset to default settings if they lose power entirely, which could harm the performance of your motorcycle or car. By installing an ammeter, you can put your mind at ease that you are on top of your voltage needs.

You can use it to measure very small electrical currents or very large ones. However, if you are a beginner, only use it to measure small currents. Large electrical currents can be dangerous. Connecting an ammeter to measure current only takes a few minutes or less. For example, they might just attach the two probes to the wire. The key to connecting an ammeter correctly is remembering that the connection is such that current will flow through the ammeter, as if it was a wire. Set the current type switch.

Current is measured in amps, and one-thousandth of an amp is called a milliamp. Multimeters can function as ammeters measurers of current , and you can use the meter to read the number of milliamps flowing through a circuit. This process usually requires connecting the probes to the appropriate ports, breaking the circuit so the current can flow to the multimeter, choosing a suitable setting on the meter, and then connecting the probes to the circuit.
Because measuring current in this manner requires the meter be made part of the circuit, it is a more difficult type of measurement to make than either voltage or resistance. Some digital meters, like the unit shown in the illustration, have a separate jack to insert the red test lead plug when measuring current. Other meters, like most inexpensive analog meters, use the same jacks for measuring voltage, resistance, and current. When an ammeter is placed in series with a circuit, it ideally drops no voltage as current goes through it.
