Things to Consider Before You Buy


R

What It's Good For

Automotive multimeters are among the most versatile devices in existence – they allow you to easily check things like capacitance, resistance, voltage, current, as well as other factors

These tools are capable of showing multiple readings, and they’re easy to see and interpret, thanks to their big digital displays. Unlike their analog cousins, you don’t have to take a really close look to see the numbers, which makes them great in poor lighting conditions or if you have poor eyesight.

An automotive multimeter shows actual values and is capable of providing an output of up to five decimal places. This makes these devices highly accurate. Another feature worth mentioning is that they can also read negative values, particularly if we’re talking about voltage. When you place the probes into opposite polarity, you’ll get a negative output. It’s yet another advantage of these devices and something that makes them invaluable to all serious petrol heads.

Q

What It's Not So Good For

Unfortunately, automotive multimeters aren’t perfect for every occasion. The most important one of them is that they don’t do particularly well with measurement fluctuations. This means that when a variation takes place, an automotive multimeter won’t be capable of representing it, and 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 many still might be out of your price range if you have a limited budget.

Also, with so many varying capabilities and with different prices, it can be tough to select just one that will best fit your individual needs. There are a plethora of options out there, so make sure to read our informative and comprehensive reviews first.

Automotive Multimeters – Our 2020 Buyer’s Guide


Before purchasing your very first automotive multimeter, there’s a couple of things you should know, in order to avoid buying a device that’s unsuitable for your needs. Ask yourself the following questions

What Is It Capable of Measuring?


Before buying an automotive multimeter, consider your level of knowledge of electrical equipment. Most multimeters are capable of measuring resistance, continuity, current, AC and DC voltage, for example. 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, accuracy is indeed an essential factor to look for. On the other hand, it shouldn’t be a serious concern for people who only use these devices 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 the most accurate.

Accurate Readings

Is it Safe Enough?


One really good thing to know is that most of today’s multimeters come with safety fuses, preventing accidents from happening. These fuses are usually attached to the back of the devices and can be easily replaced. Of course, that doesn’t mean you shouldn’t consider the acceptable limits of your model. The highest tolerable values of your particular device are generally listed in the manufacturer’s user manual.

If you’re planning to purchase a model with detachable probes, don’t forget to check out if these probes have the correct placement. Due to safety considerations, multimeters often have color coding on the probes.

How’s the Build Quality?


Sometimes, electrical projects will require a professional to work in some really inconvenient locations, such as 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.

Is It Reliable Enough?


A reliable and 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 set period of time. 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 useful to have a low battery warning signal — an excellent measure for avoiding unexpected power cut-offs.

With these factors in mind, you should be able to purchase a model that will serve you for the years to come. Good luck!

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 items with it, while easily reading values on a big digital screen.

Unlike some years ago, these tools are no longer too expensive, and should be well within the budget for most of us. 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!
