Digital multimeters are a useful test tool that can check the levels of electronic components. They troubleshoot electrical issues by measuring the voltage of alternating and direct currents and provide accurate measurement results. They can also measure the voltage levels and the resistance. They can be used to test car batteries, wall outlets, wires, circuits and other electronics. Multimeters can help beginners test comfortably without the need call an electrician. Here are the best automotive multimeters on Amazon.

How to use a multimeter
Make sure you are familiar with the instructions provided on the packing before getting started. Once you are ready, turn on the multimeter and turn the selector knob to either DC or AC and match it to what type of current you are testing for. Next, place the red probe onto the positive terminal and the black probe on the negative terminal. Soon after your meter should start displaying numbers to let you know the levels of the component it’s testing.
What can a multimeter be used on?
Multimeters can be used for a variety of electrical components and devices. It’s suitable for testing wall outlets, wires, circuits, batteries, car batteries, etc. It’s a great tool to have for testing in home, office or industrial settings.
Analog multimeter vs digital multimeter
Both types of meters are great devices that provide quality measurements in similar ways, but still have a few differences. Digital meters show the numbers directly on the screen while analog meters have a dial that turns to show the numbers it’s receiving. Analog meters are cheaper and more responsive than their digital counterparts, but tend to be less accurate and can be harder to read.
Voltmeter vs Multimeter
Multimeters can measure voltage, current and resistance while voltmeters only measure voltage.
