Good for
Automotive multimeters are among the most versatile devices in existence – they allow one to easily check things like capacitance, resistance, voltage, current, and other factors. These tools are capable of showing multiple readings that are easy to see and interpret thanks to their big digital displays. Unlike with their analog cousins, one doesn’t have to take a really close look to see the numbers, which makes them great for the people with poor eyesight.
An automotive multimeter shows actual values and is capable of providing an output of up to 5 decimal places. This makes these devices highly accurate. Another thing worth mentioning is that they can also read negative values, particularly if we’re talking about voltage. When a person places the probes into an opposite polarity, he’ll get a negative output. It’s yet another advantage of these devices and something that makes them invaluable to all serious handymen.
Not Good for
Unfortunately, the automotive models also sport some disadvantages. The most important one of them is the fact that they don’t do particularly well with the measurement fluctuations. This means that when a variation takes place, an automotive multimeter won’t be capable of representing it, and it will instead calculate a single reading or record an error.
Another disadvantage is that they can be somewhat expensive. As far as we’re concerned, these tools are now far more affordable (especially when compared to analog models) than they once were, but they still might cost too much for some people. Also, with so many different sets of capabilities and with different prices, it can be very tough to select just one that will fit your individual needs the best. There is a plethora of options out there, so make sure to take a look at our informative and comprehensive reviews first.

The great thing about the Innova 3320 is the battery load test function. It’s used for checking whether your car battery (or any battery) is performing well. It may sound like it’s not a big deal, but if you take a moment and think about it, you’ll see that it’s great because you don’t have to buy separate instruments for checking the batteries, but instead use the Innova 3320 for diagnosing the battery condition.
It also has an auto-ranging function which will help you to save some time and effort. It selects the proper range automatically, so you don’t have to do it yourself. This feature is especially useful for people who aren’t experts when it comes to dealing with electricity, batteries, and multimeters in general. The large digital display is also one of the important things about this unit because most of nowadays multimeters have a small and illegible screen which can be a burden most of the time.
The Innova 3320 also has a single-setting resistance function for both DC and AC. The overall design is neat; it has a built-in stand and wrist wraps which guarantee a firm grip. Because of the sturdiness of this unit, it can also withstand bumps and drops. It comes with a safety certification issued by the UL, and while it doesn’t seem impressive, it offers contentment and peace of mind. Although some doubt its reliability, you can rest assured that you’re going to get precise and accurate readings.
One thing that makes this company stand out is their customer support. A lot of manufacturers neglect their customers and provide poor support. However, Innova has a team of people who are ready to answer your questions and help you with potential issues. They are available Monday-Saturday in English and Spanish.

Automotive Multimeters – Buyer’s Guide
Before purchasing your very first automotive multimeter, there’s a couple of things you should know about in order to avoid buying a device that’s unsuitable for your needs. Ask yourself the following questions:
What Things is it Capable of Measuring?
Before buying an automotive multimeter, one has to consider his own level of knowledge of electrical works. Most models are capable of measuring things like resistance, continuity, current, AC and DC voltage, and other things. If you consider yourself to be a professional user, frequency and capacitance would be among other essential features of your future device.
Are the Readings Accurate and Trustworthy?
The accuracy of a multimeter is something that determines the volume by which the shown reading will be different from the input value. If you’re working on a professional level, the accuracy is indeed an essential factor to look for. On the other hand, it shouldn’t be a serious concern for the people who use these devices only in their own households.
One important thing to know here is the fact that you might need to calibrate your model to keep it precise from the very first day. Models that show readings in more digits are typically considered to be more accurate.
Is it Safe Enough?
One really good thing to know is that most of today’s multimeters come with safety fuses that prevent accidents from happening. These fuses are usually attached to the back of these devices and can be easily replaced. Of course, that doesn’t mean that you shouldn’t consider the acceptable limits of your model. You should be able to find the highest tolerable values of your particular device in the user’s manual.
If you’re planning to purchase a model with detachable probes, don’t forget to check out if these probes have a right placement. Due to safety considerations, multimeters often have color coding on the probes.
How’s the Build Quality?
Typically, most of the electrical works will require a professional to get near some really inconvenient locations, such as the electrical poles, high-rise buildings, damp basements, and other similar areas. In these kinds of situations, it’s of crucial importance to have a tool that can be attached to your belt.
Fortunately, most of today’s quality models are quite capable of surviving falls up to 10 feet.
Will it be Reliable Enough?
A reliable and a consistent model won’t leave you helpless when you need it the most. Some multimeters feature the so-called auto-shutoff function which puts the entire device to sleep once it’s been inactive for a couple of minutes. As you can already guess, this saves the battery’s energy and allows the tool to work longer without the need to change the battery.
Furthermore, it’s nice to have the low battery signal – it’s an excellent measure for avoiding unexpected power cut-offs without being warned first.
With these factors in mind, you should be able to purchase a model that will serve you for the years to come. Good luck!
The Conclusion
Having an automotive multimeter by your side at all times can be incredibly helpful if you’re a serious handyman, whether you’re just fixing things around your own house or making a living out of it. With a quality model, you’ll be able to check a myriad of things with it while easily reading values on its big digital screen.
Unlike some years ago, these tools aren’t so expensive anymore, and one can easily purchase a reliable model for himself. The only issue here is the fact that there are so many different brands and models on the market. Selecting just one model can be a tough business!
But, have no worries – we’re here for you. We decided to sit down and thoroughly analyze the world’s most popular automotive multimeters and give you an insight into their features, functions, design, price, advantages, and flaws. Our reviews are very informative but still comprehensive and straightforward enough, and they should assist you in finding the right device for your needs.
Don’t forget to check out our Buyer’s Guide to know which features to look for while buying your very first model. Follow the points mentioned there, and you’ll end up with a reliable tool that will serve you for the years to come!
