Top 11 Best Automotive Multimeters For 2020

It’s something you will never shy away from as a car owner! In fact, it doesn’t even matter how often you service your car. Well, am talking about those occasional electrical gremlins. It’s one of the inevitable issues that you need to be prepared to face as a car owner.

Of course, servicing your car more often will minimize the likelihood, but the slim chances of happening left after servicing could capitalize with time and eventually cause the problem.

Calling your mechanic to come and make things right is an option, but it makes little to no sense to have him travel a long way to fix something you could do in no time!

Wondering how you can do it? Well, let me teach you some electrical engineering basics! To diagnose any electrical fault, whether at home or in your car, you need to measure three basic things; the current, voltage, and electrical resistance. Literally, you will require three devices for this; ammeter, voltmeter, and ohmmeter.

But wait- what about getting a single device that combines all these functionalities? Sounds better, right?

That’s why you need to invest in a decent automotive multimeter. Accuracy here is key, and that’s why you should never skimp on one. So should you get the high-end options? Not exactly- get your perfect device from one of our 11 best automotive multimeters.

Can you check car fuses with a multimeter?

Yes. A digital multimeter will work in pinpointing faults in your car’s electrical system. However, for the best results, you need to choose a model that works well for automotive applications.

How much does a multimeter cost?

Multimeters have a wide price spectrum. We have some models that work well for huge budgets, others for medium-sized budgets while the rest come with low-budget shoppers in mind. However, don’t just settle for a cheaper model at the expense of quality.

Are cheap multimeters any good?

We have some inexpensive models out there that will work comparably to other high-end models. However, typically we don’t expect them to pack as many special features as we have in more expensive models. But if you are one of the people who aren’t after lots of bells and whistles, you can still get a decent inexpensive model for the basic tests.

What are the 2 classes of multimeters?

Multimeters can either be analog or digital. Analog versions use a needle to display readings whereas digital models display values on a screen. For this reason, DMM is easier to use than the analog versions. However, analog models cost less.
