A multimeter is a vital device for those who are dealing with electrical malfunctions. Especially if you are an automotive expert, you would definitely want to have one of these in your tool box. But in case you haven’t know about this yet, we’re going to explain to you what it is, why you should use it, and how to use it. And after that, here is the list of the best multimeters that you probably want to take a look.

There are two types of multimeters, analog and digital. The analog one is often referring to VOM (Voltmeter-Ohmmeter-Milliammeter). And like how it’s sound, this type of multimeter only capable of three different measurements. It has a bar that shows all the information of the current and you must adjust it manually to get the results. On the other hand, the digital has a display screen that shows all the important information and other additional features. But expert often prefers analog ones better because they’re more precision. This is because the digital multimeter often has a much larger impedance than the analog.

Why use a multimeter?

You can use a multimeter to check for various electrical faults and malfunction. This device also enables you to measure impedance when working with fuses, switch, or sensors and other components of an electric device. Other multimeters (mostly digital ones) also have the ability to read the continuity of the current, therefore, enable the engineers to fix broken wires and any other parts of the devices that the current is passing.

There are two types of multimeters, the auto-ranging, and the manual-ranging. The auto ones often have other additional feature. The auto detect function will guesses what you’re using it for base on the received information from the probes. For the manual one, you must select the input range that you’re going to measure. On the multimeter, there is a switch that can be used for changing between different measurements. There are three measurements that always appear on the switch, its Voltmeter, Ohmmeter, and Milliammeter. Sometimes, there is also an impedance measure function but the three above is irreplaceable. There are two jacks which are the input and output for the electric current you want to measure. Just simply put the input jack (usually the black one) on one side and the output on the other side, the information of the electric current will be display on the screen or the bar on your multimeter. And the less impedance your multimeter has, the result will have more precision. That’s why experts love using manual ones. And if you’re working with a current that is above 30V, you should consider buying a good quality multimeter with safety features. You’ll never know what could happen if the electric leakage happen.
