Buyers’ Guide

Well, if you’re still doubtful and can’t decide which automotive multimeter will be liked by your car, then here comes a complete guide that might help you choose the best one based on your needs and requirements. 

Why should you buy an automotive multimeter

That’s a good question, and we’d say that there are two good reasons to get this portable device:

First, you can save your bucks! Trust us, nothing’s more galling than a hefty bill for repairing a vehicle. Though there are some fixes that can only be dealt with by a pro mechanic, there are many more that you can do all by yourself with the help of a multimeter. 

Second, certainly, you love your car and look after it, right? But you know what – its various components demand care too. And that can be done with the help of a maestro tool: an automotive multimeter. Yes, that’s true. Such a multimeter will keep a good check and balance of your car’s electrical system. 

You can’t know if your automobile’s battery is about to die, or its other parts are expiring, but an automotive multimeter can tell and make you aware before it becomes a bigger job.

How to use an automotive multimeter? 

Using an automotive multimeter isn’t challenging! It totally depends on the parts that you need to measure. Speaking of the most effortless test is the battery check, and you can do that by attaching the automotive multimeter to the battery connectors and then reading the voltage from the display screen. Pretty simple, right?

However, they can also be used for many technical tasks. But for that, we’d recommend you to properly go through the manuals or online guides before you go ahead. 

What are the things that you should consider before buying an automotive multimeter? 


If you’re a beginner or find it difficult to operate a multimeter, then we’d recommend you to look for the one with an auto-range feature in it. This will help you save your time by setting the ranges automatically and getting the job done.

True RMS

Well, that’s a complicated thing as it involves math. But making it simpler, an automotive multimeter with true RMS feature in it will give you the most accurate readings across any other multimeter.

Overload Protection 

No one likes to be electrocuted, so we’d recommend you look for the automotive multimeter with an overload protection feature in it, as it offers more safety. 

Rubber Edges

A good case or rubber edges will protect your little automotive multimeter when it drops. Moreover, it will increase the lifespan of your device. 

How can an automotive multimeter be used for car diagnostics? 

Diagnosing your car with an automotive multimeter isn’t laborious. Let’s discuss the three main purposes of an automotive multimeter to diagnose your vehicle:

  1. The most common use of multimeter is testing continuity, which tells you whether or not the current is flowing through parts of the car. 
  2. Undoubtedly, you’d be familiar with the speaker system of your vehicle, and that certainly requires voltage to work properly. Now, you can measure voltage within parts of the automobile like powerful amps or heavy bass subwoofers, with the help of an automotive multimeter.
  3. The third thing that you can measure with your automotive multimeter is resistance. Many parts of your car such as ignition coils, fuses and sensors offer resistance, and measuring it can tell you whether that part needs to be replaced or not.

Some Useful Tips and Tricks about Multimeters

Here are some tips that prove to be useful:

  • If you’re planning to test a system, always make sure that your automotive multimeter is safety rated for the voltage of that system. You should know that CAT III safety is up to 1000 volts and CAT II safety is up to 600 volts. However, a car battery holds between 12 to 14 volts – which is even lesser than wall outlets, so it’ll be safe to use any of these. 
  • We should always be cautious while playing with electricity or electric appliances, as they can be hazardous. Therefore, we’d recommend you to use an automotive multimeter with an overload protection feature in it. This will give you an extra protection on all ranges. 
  • Low-quality models need to be fine-tuned every once in a while so that they continue to give accurate results. Probably you’d have automotive calibration services in your area.
  • These multimeters are sensitive little fellows, so you shouldn’t use them roughly and keep them safe.

Frequently Asked Questions

It doesn’t matter if you’re a professional or an amateur, you should always have an automotive multimeter for your vehicle.

And if you haven’t figured it out yet, then take a quick look at the list of things which will help you get the perfect one. 

Is it safe to use a multimeter? 

As far as safety is concerned, we’d say it may or may not be safe. No one can guarantee a multimeter to be cent percent safe.

And why is that so? 

It’s pretty simple, as working around with electricity has never been safe. So, no one knows what’s going to happen the next minute while handling electrical equipment. 

But, if you take all the precautions then you’ll be alright. Moreover, there are good automotive multimeters available in the market with plenty of built-in safety features like overload protection or reverse polarity. So, if you’re using the right tool in the right way, you’ll be safe.

Are the readings of the multimeter trustworthy? 

Well, multimeters aren’t 100% accurate, there’s always a chance of errors. Even in the most expensive automotive multimeter, there exists an error of 0.1% – which doesn’t make much difference. So basically, these automotive multimeters are pretty much accurate and give a precise reading for the vehicle diagnostics and repair.

How can you replace fuses? 

Fuses are used for safety in an automotive multimeter, but they can blow out too. Then there’s the need to replace them and that’s pretty simple. All you need to do is check out the instruction manual of your tool and do what it says. 

Furthermore, order some replacements while ordering the automotive multimeter, so you’d have some back up if you happen to burn them. 

How to identify if a wire is live with your automotive multimeter?

Identifying a hot wire or a neutral wire is a piece of cake for an automotive multimeter. Just set the voltage setting of your multimeter on the highest AC range then attach the probes against the wire.

Now it’s time to check:

If you get a voltage reading on your multimeter then the wire is live and if you don’t then it’s neutral. Quite simple! 

What is meant by CAT safety ratings? 

Well, CAT rating is a safety feature that tells about the internal safety settings of your automotive multimeter. There are multimeters available with CAT IV rating – cover the most dangerous level of transient overvoltage, CAT III rating up to 1000 volts, and CAT II safety up to 600 volts. Besides, CAT III or higher safety rated multimeters can safely measure live breaker panels and can easily handle high potential voltage and energy.

However, the multimeters with CAT II or lesser safety rated can be used to test for bad circuit breakers that are disconnected from the live wiring. Moreover, we’d highly recommend you not to use such multimeters on anything more powerful than a wall outlet. 

How can you check the highest range for measurement of any quality? 

Your automotive multimeter clearly mentions the ranges which it is capable of measuring. It’s right there on your device! you can have a look.

Also, it tells the output measurement – lower quality models give readouts up to 2000 places while premium ones have a readout of about 6000 places and are more accurate even at higher ranges. 

Can an automotive multimeter be used with any car or just with some specific models? 

Multimeters are not specific in any genre, in fact, they are handy tools for every automobile. You can use them on your car, motorbike, truck, SUV, boat, airplane, etc. One and only one automotive multimeter can be used with them all.

However, in spite of automotive diagnostics, your multimeter can test household appliances too! Name any electronic and your multimeter will be ready to troubleshoot it.

How you can measure current if the multimeter has different ranges? 

Measuring current with an automotive multimeter is technical, as the electricity flows through the multimeter. So, you need to be quite cautious. Not only this, you have to select the range too and if that goes wrong, trust us that won’t be good. 

However, if you want to prevent the damage, then remember that it takes about 400 amps to start a car and about 1000 amps for the truck. Moreover, to be on the safe side you can set the range above these levels and dive in. But, if you’re still scared of setting the ranges, then buy the automotive multimeter with an auto-ranging feature in it. 

Final Thoughts

This concludes our list of best automotive multimeters for your automobile. 

We’d recommend you to buy Etekcity Auto Ranging Clamp Meter if you are looking for a compact, versatile, accurate, safe, portable and easy to read automotive multimeter
