The Best Automotive Multimeters 2019

One of the first items that you will purchase as an automotive student is a Multimeter. Below are some things to look out for when you purchase a multimeter and or if you're looking to upgrade equipment that you have that might be better suited for your automotive work. Multimeters are available in both analog and digital formats and is a diagnostic tool used to measure electrical properties the three most likely things that you might measure with a multimeter would be the AC or DC voltage resistance or current.

Multimeters take the properties of an ammeter, and ohm meter and a voltmeter and rolls them into one. they are commonly used to detect potential malfunctions with your car battery, electrical issues and pinpoint the exact cause of those issues.

As an amateur mechanic, a vital to diagnosing an electrical fault in a car is an automotive multimeter. The latest multimeters on the market can even connect to a smartphone or other forms of data on top of real-time data.

Digital Automotive multimeters are the better buy compared to using or buying a analog alternative this is because the analog multimeter alternative has a lower input impedance and are often limited to amp, ohms and voltage readings.

The purposes of a digital multimeter for car Diagnostics.

An automotive multimeter could be used for three primary purposes. The most common reason to use a Multimeter would be to test continuity. Be continuity testing will tell the user weather car whether parts of the car are continuous, and thus whether or not an electrical current can flow from one end to the other. When there is no new continuity you will know that there is a break somewhere in the circuit and the part likely needs to be replaced.

You can also use your multimeter to measure resistance and parts of your car, like fuses ignition coils and sensors. Measuring resistance can help determine whether a part of a headlight, for example, needs to be replaced.

the third use is to measure voltage with in parts of a car. As you probably know, heavy bass subwoofers and Powerful amps will require a certain amount of voltage to work, otherwise your home speaker system will not work.

In the automotive world, having the correct tools to diagnose problems makes things much easier. Even the best automotive scanners may miss many electrical issues that multimeters will find in seconds. This is probably the most important purchase that you will make starting out as a student.

How to use an automotive multimeter

In all in all tests with your multimeter, you will first want to make sure there is no current running through whatever component of your car that you’re testing. this is a safety measure to make sure that you don't do not get electrocuted in the process of testing.

in order to test continuity, you will want to First switch the dial on your multimeter to continuity test mode. Then, you will need to plug your probes into the hole they fit into, known as the forts. Finally you will need to put one of their probes on each and of whatever component your testing for continuity.

The probes work by sending an electric current through the component. so if the circuit you're testing is in fact continuous the digital readout may say 0 or your multimeter will admit a beeping sound. If the circuit is not continuous, the display will show either a 1 or o l for open loop. when testing for resistance you will skip the step of plugging your probes back in, as you will assume that you have and left them in front of the last test.

You will need to switch your meter to the resistance setting. You will then need to set the range of resistance you want to test for, and if you are not sure what to use just use the highest setting because you can always adjust it later.

Then, to test a component you want to place one Probe on each end. if the read on a multimeter does not say anything, set the range to a lower setting because that will probably mean it is too high. Adjust the range until you find the range where you actually get a readout. Repeat this process was testing for voltage. Simply put 1/4 old on each end of the component you are testing and wait for the redoubt. Adjust the voltage range on the multimeter if necessary, and you will have effectively used your meter to test for all three major things the tool can be used for.

So what are the features of an automotive multimeter? one desired feature of the multimeter that you want is the ability to test for a variety of different voltage ranges. Not all multimeters come with disability, so make sure that you find one that does.

For example, if you're testing a component that features a voltage you do not have the ability to test on your meat on your multimeter, you may get a negative read out from that test when the component is not actually broken. This is one of the biggest elements to look for when looking to purchase your multimeter as a student. Another feature that you may want on your multimeter is the ability to measure both alternating and direct current voltage's. Why most products will probably run on direct current voltage is, it is important to be able to measure alternating current as well as have all your bases covered. Again, not having this feature could be too bad readouts on your tests. Lastly, you want a multimeter with the ability to measure ohms. Sometimes multimeters will only have the ability to do a simple continuity test rather than actually measuring ohms, but you want to spend a few extra dollars and just get one that does everything and measures ohms.
