Multimeter Buyer’s Guide

Now that you know a little more about ten of the best multimeters you can purchase, it’s time to dive into the details about the best multimeter for you. We’ll dive into some useful tips on how to use your multimeter, break down the differences between AC and DC voltage, and even highlight some of the best possible accessories you can pick up for your multimeter.

Keep reading and we’ll break down everything you need to know to go from a multimeter novice to an electrical guru!

AC vs. DC Voltage

multimeter car

If you’re trying to troubleshoot electrical systems one of the first things you need to figure out is the difference between AC and DC voltage.

The simpler of the two voltages is DC voltage. In a DC voltage system current always travels the same direction. However, the tradeoff to these systems is that they can’t carry a ton of voltage without much larger wires.

This is why DC voltage systems have much lower voltage amounts. Typically, you can find DC voltage in automotive and batteries, and you’ll typically have voltage amounts under 24 volts. Any multimeter you purchase should be able to easily handle any DC voltage system.

AC voltage is “alternating current,” which you can find in typical 110-volt and 220-volt outlets throughout your home. Unlike DC systems where the voltage always travels in the same direction, in AC systems the voltage rapidly alternates the direction it goes.

This allows smaller wires to carry more voltage, which is why it’s so prevalent in homes and other areas where you need higher voltage amounts to power everything. However, AC systems present more of a challenge for multimeters.

Not only do they present higher voltages to read, but since the voltage isn’t always going in the same direction, it can confuse some multimeters and give you inaccurate readings. If you’re planning on using your multimeter on AC voltage, ensure you’re getting a multimeter that can handle it!

Non-Linear Loads

Another thing you’ll need to keep in mind when getting a multimeter is whether any of the systems you plan on testing have a “non-linear” load. These systems use fluctuating voltage as a part of how they work.

These systems usually work on some sort of loop. For instance, they might give off 6 volts for three seconds, 9 volts for three seconds, then 12 volts for three seconds before going back to 6 volts.

These systems can work with the voltage fluctuating after just a fraction of a second, or they can last for several seconds before changing, it all depends on the system. These systems present major problems for lower-end multimeters since they only check the voltage at any given point in time.

However, higher-end multimeters can track these fluctuations and display a chart to show you what’s going on over time. This allows you to accurately track the function of the device and the voltage to figure out what’s going on.

Voltage Ranges

Whenever you’re using a multimeter, you need to take the time to look at the range the multimeter is using when giving you results. There are two ranges a multimeter will use when measuring voltage, millivolts and volts.

Volts is the typical reading for most circuits, and you can tell when it’s displaying volts when the unit of measurement next to the reading is a “V.” However, if you’re dealing with extremely small amounts of voltage the “V” might switch to an “mV.”

This stands for “millivolts.” Each volt consists of 1,000 millivolts, so if you see an “mV” in the unit of measurement range, it’s important to take notice! This is especially true for multimeters that use an auto-ranging feature.

It’s a nice feature since you don’t ever have to worry about switching modes to get accurate results, but if you’re not careful it can lead to you misreading results. This happens when you’re expecting a reading in volts, but there’s only a residual amount of voltage in the system so it switches to millivolts. If you don’t look at the unit of measurement, it’s easy to mix things up!

Helpful Accessories

If you’re getting a multimeter, there’s a good chance you’re going to want a few accessories to make it easier to use in different situations. We’ve highlighted some of the most popular accessories you should consider getting for your multimeter to unlock more features and make it easier to use for different jobs.

Lead Kits

There are tons of lead kits out there, and you should consider getting a comprehensive option like this one to go with your multimeter. Ensure it’s compatible with the multimeter you’re getting, and then spend a little extra money to get an excellent lead kit.

The extra leads ensure you can get a secure connection on a wide range of sockets, plugs, and lines. Getting a secure connection is the only way to get reliable readings, making it easier to get connections in different situations.

A few bucks on a lead kit will save you hours of frustration and ensure you get accurate results. They’re well worth every penny.

Amp Clamps

If you want to use your multimeter to test for amperage, you’ll need an amp clamp to get the job done. They work hand-in-hand with multimeters, and they’re a lifesaver for advanced electrical troubleshooting.

Most DIY electricians don’t need an amp clamp, but if you’re looking to take the next step in electrical troubleshooting and work, an amp clamp is a natural starting point. There are tons of great options out there, but we like this amp clamp by Klein Tools.

Voltage Probes

There are tons of voltage probes out there, and they provide a quick and easy way to tell if a line has power before using your multimeter. Voltage probes come in tons of different shapes and sizes and depending on what you go with they work for various types of electrical circuits.

While you can invest in a standalone voltage probe if you want, the Amprobe PK-110 from our list above comes with two different voltage probes you can use in both automotive and household applications. It’s a nifty feature, although it’s not completely necessary if you already have a multimeter since they can test for voltage too.

Power Probes

This isn’t exactly an “accessory” for a multimeter, but it’s a lifesaver in many electrical troubleshooting applications. These handy devices allow you to power up various devices by applying voltage directly to the device.

When you’re trying to troubleshoot various components like starters, sensors, or just about anything else, a power probe takes all the guesswork out of the situation. You can quickly test the component and rule out that part of the problem.

If the component doesn’t work you know that’s the problem, but if it does you know it’s a problem with the power supply.

There are tons of great power probe options out there, but we really like this one by Clamshell. If you’re doing a lot of electrical troubleshooting, do yourself a favor and pick one up.

Backup Fuses

All right, this isn’t a completely necessary accessory to have, but it’s a good idea to have them on hand. If you’re checking amperage at any point and you forget to switch the leads back to voltage, you’ll blow the fuse on the multimeter.

When this happens you can’t use the amperage function on the multimeter anymore. Having a few extra low-cost fuses on hand ensures that if you accidentally blow the fuse because you forgot to switch things back you don’t lose those features until you can get a new fuse.

If you’re looking to purchase a multimeter it’s only normal to have a few questions. We understand, and it’s why we decided to answer some of the most frequently asked questions about multimeters for you here.

Why Do Fluke Multimeters Cost So Much?

The primary reason Fluke multimeters cost significantly more than the competition comes down to the quality of materials in them and the quality of results. Fluke multimeters give more accurate results and last longer, and that’s why they cost more.

What Are the Three Most Important Things a Multimeter Can Measure?

Multimeters check voltage, resistance, and amperage. The ability to check all three of these things are what separates a multimeter from a simple voltmeter.

What Does OL Mean on a Multimeter?

If the multimeter reads “OL” it means open loop. When this happens on the multimeter it means the circuit you’re trying to test is open and not complete.

Do You Need an AC or a DC Multimeter?

This all depends on what you’re checking. If you’re using your multimeter for automotive purposes are for batteries, you’re using your multimeter to check DC voltage. However, if you’re using your multimeter for household outlets and lines, you need one to check AC.

If you have a multimeter that can check AC voltage it should be able to easily handle DC voltage too.

Now that you know a little more about the various multimeters you can purchase, all that’s left is for you to pick the best one for you. If you’re still a little unsure about which option is right for you, there’s a reason the Innova 3320 is our top choice, and the AstroAI 2000 is an excellent choice for those on a tight budget.

Of course, if you’re a professional, the Fluke 115 might cost a bit more but it’ll deliver the best possible results. What’s important is that you get a multimeter on order so you can use it the next time you’re trying to complete some electrical work!
