A multimeter is a powerful tool for measuring electrical values such as voltage, resistance, and current, commonly used in automotive and household applications. This beginner’s guide will walk you ...

3. Complete the Circuit and Listen Simply probe to the other end of the circuit and listen. Again, the multimeter’s alarm signals a complete circuit. Multimeter Resistance Test Disconnect battery 1.

Safety Tip: As previously mentioned, do not test a circuit that exceeds your multimeter’s capability. Multimeters are “fused” at a maximum amount of voltage, which is typically lower than ...

For all of you who have a multimeter thrown in a drawer or toolbox but don’t know how to use it, these instructions will help in your search for missing voltage.

Automotive circuits will use either, depending on the circuit. To test the battery, you’ll want to use the DC voltage setting. This will be illustrated by a ’V’ with a straight line beneath it.
