Fact checked by Emily EstepReviewed by Larry Campbell
Multimeters are battery-powered devices that are used to measure various properties in electrical circuits, devices, and components. They come in handy when carrying out repairs or installing anything that runs on electricity in your home, including HVAC systems, basic wiring, or even your car. Shaun Murray, electrician and Director at Gimpel Electrics, says, “As an electrician, a multimeter is my go-to tool for measuring and troubleshooting electrical systems. It's a versatile instrument that helps me accurately measure voltage, current, and resistance in circuits. With a multimeter in hand, I can quickly diagnose faults, ensure proper connections, and verify the functioning of electrical systems.”
Kim Hopkins, electrician and owner of The Electric Connection, has further advice, “When it comes to buying a multimeter, there are a few things to consider. Make sure it can handle the voltage range and current capacity of the electrical systems you're working with. Accuracy is key, so look for one that gives precise readings. Some cool features to have are auto-ranging, which saves you from manually selecting the range and a built-in continuity tester. Oh, and a backlit display is a lifesaver when you're working in dimly lit spaces. Lastly, go for a reputable brand known for reliability and durability. You want this tool to last! And of course, keep an eye on the price to make sure it fits your budget.”
We evaluated numerous multimeters from all the top brands based on their accuracy, range of included tests and measurements, extras such as backlit displays, versatility, ease of use, and overall value.

Final Verdict
For the best multimeter overall, we recommend the Fluke 117, which is a professional-quality tool that is extremely accurate, carries out a wide range of measurements, and has desirable extra features including a backlit display, True RMS capabilities, and no-contact voltage detection. But if you prefer a multimeter that is very inexpensive, although only able to carry out the most basic measurements, then we like the AstroAI AM33D.
What to Look for In a Multimeter
Accuracy
A multimeter is only as good as its accuracy. Jeff Brandlin, a licensed electrician and owner of Assurance Electrical Service, says, “Accuracy is the most critical factor when choosing a multimeter. The device has to have close measurements from the measured values and the actual value. Choose a multimeter with a high level of accuracy especially when you are dealing with complex electrical issues.”
The accuracy of a multimeter is usually expressed as +/- %; for example, a multimeter with accuracy of +/- 2% might have readings within a range of 2 percent below or above the actual number. While 2 percent is generally considered the minimum level of acceptable accuracy in a multimeter, many of these devices are far more accurate than that. Our Best Overall, the Fluke 117, has an accuracy of +/- 0.5%.
Basic Measurements
There are three basic measurements that any multimeter should provide: current, voltage, and resistance. Generally, you can use the tool for both AC (alternating current, which is the electrical current in a device with a plug) and DC (direct current, which is the electrical current in a device powered by a battery) measurements.
Current is measured in amperage, commonly abbreviated as amps. Current is the flow of electricity through an electrical system, similar to a current of water moving through a hose. Shaun Murray, electrician and Director at Gimpel Electrics, says, “Multimeters are invaluable for testing current flow in circuits. I rely on this feature to measure the current draw of appliances, troubleshoot electrical faults, and ensure that circuits are properly connected. By accurately measuring current, I can pinpoint any excessive or inadequate current flow that may be affecting the system.”
Voltage, measured in volts, is the pressure that forces the electrical current through electrical wiring. Murray says, “One of the most common tasks I perform with a multimeter is measuring voltage levels. It allows me to test batteries, check power outlets, assess circuit breakers, and determine voltage levels in electronic devices. This helps me identify any voltage irregularities or potential issues in the electrical system.”
Resistance is measured in ohms, which are sometimes indicated with the Omega symbol Ω. All electrical wires have a certain amount of natural resistance to electrical flow. Murray says, “Testing resistance is another crucial application of a multimeter. It enables me to evaluate the continuity of wires, verify the resistance of specific components such as resistors, and diagnose faults in circuits. This helps me identify any breaks or excessive resistance that could be affecting the overall performance of the electrical system.”
Advanced Measurements
Most multimeters have more than the basics. Some of the additional common measurements and testing capabilities you may encounter include:
Continuity, which indicates whether or not electrical current has an unbroken path. Murray says, “Multimeters come with a continuity test function that beeps or indicates if there is a continuous electrical path between two points. This feature is incredibly helpful for me to identify open or short circuits, test connections, and ensure proper conductivity throughout the system.”
Capacitance, which is a measurement of an electrical circuit or component’s ability to store a charge.
Temperature, which can affect the function of some types of electrical components.
Diode testing and other diagnostic tests of various electronic components can be important when doing repairs on electronic devices and systems. Murray says, “As an electrician, I often need to diagnose the functionality of various electronic components such as diodes, transistors, and capacitors. Multimeters allow me to test these components, check their values, and identify any faulty or malfunctioning parts that may need to be replaced.”
Dwell time measures current flow in a car's ignition system.
Duty cycle measures the amount of time an electrical component is operating within a specified period.
Our Best for Beginners choice, the Extech EX330, can be used for 12 different functions.
Display Type
There are two basic display types: analog and digital. Analog multimeters, such as our Best Analog pick, the Gardner Bender GMT-318, have a simple dial face and a needle that swings along the dial to indicate measurements. These old-fashioned multimeters can only do the basic tests; you won’t get anything advanced or fancy on these devices. While analog multimeters are generally inexpensive, the vast majority of multimeters sold today are digital. These tools have a digital display which is easy to read, and most importantly, is usually more accurate than trying to gauge the exact reading on an analog multimeter.
The best digital multimeters have backlit displays, which are especially useful when using the tool in a garage or other area that doesn’t have good lighting. We especially like our Best Clamp Meter, the Klein Tools CL800, which has a large, backlit LED display.
Another consideration for the digital multimeter’s display is its resolution or count. This refers to the number of digits the tool can display on its screen; the more digits, the more precise the result.
Standout Features
Auto-Range
When carrying out any of the basic multimeter tests, you need to have some idea of the approximate electrical current in the device or circuit you are testing. Less expensive or less advanced multimeters leave it up to you to manually enter that number, but a multimeter with auto-range can automatically detect the range of current/voltage being tested, making it a far easier and faster tool to use. A good auto-range will determine the range of current/voltage within just a second or two. Our Best for HVAC, the Fieldpiece SC260, has auto-range along with other desirable features.
True RMS
RMS stands for “root mean square,” and while somewhat complicated, it basically refers to a multimeter’s measurements of the fluctuating currents in an AC system, such as the electrical wiring in your home. The typical multimeter provides an average of the readings, which is sufficient for many uses. However, a multimeter with True RMS automatically carries out a series of complex mathematical equations to arrive at a more accurate result. This can be important when using your multimeter to test electrical systems in an HVAC system, an electric car, or other delicate electronics that require very precise results. Our Best Splurge pick, the Fluke 179/EDA2 6-Piece Combo Kit, has True RMS capabilities.
Accessories
Just about every multimeter comes with a set of two probes for use in carrying out tests. Some include additional clips or clamps, as well. Other accessories might include a carrying case or holster, or additional probes for more advanced tests. Our Best for Automotives pick, the Innova 3340, also includes a temperature probe, clamp, and clips for use while doing automotive diagnostics.
Frequently Asked Questions
What is a multimeter used for?
While not every DIYer needs a multimeter, if your projects involve electrical systems or components, then this is a tool that deserves a spot in your tool box. Kim Hopkins, electrician and owner of The Electric Connection, says, “ If you're into DIY projects or you work with electrical stuff, having a multimeter is a game-changer. It helps you troubleshoot problems by pinpointing voltage drops or irregularities in circuits. You can use it to check if a component is faulty or if there are any wiring issues. Trust me, it's a real lifesaver. A multimeter is great for testing and verifying the presence of electrical current. It's also handy for checking if wires or fuses have continuity, meaning they form a complete circuit. And let's not forget about measuring resistance in different components. So whether you're fixing a broken appliance or just curious about how things work, a multimeter has got your back.”
How do you use a multimeter?
While multimeters seem like very complicated devices, the actual use of one is not that difficult. Kim Hopkins explains the basics, “Start by turning the dial to the function you need, like voltage, current, or resistance. Then, grab your trusty multimeter leads—usually a black one and a red one. Pop the black one into the COM (common) port and the red one into the VΩmA (volts, ohms, milliamperes) port. Next, connect the leads to the circuit or component you want to measure. Finally, take a peek at the multimeter's screen or analog dial to see the measurement. Easy peasy!”
Do I need to buy an expensive multimeter?
If you only need a multimeter for basic projects or repairs around your home, then there’s no need to break your budget on a high-priced, professional tool that may well have more capabilities than you’ll require. Before purchasing a multimeter, consider if you need all of its testing capabilities and features. If not, there may well be a less-expensive model that will still be sufficient for your needs.
Is a digital multimeter better than an analog multimeter?
While analog multimeters are generally quite inexpensive, and may be easier to use than a digital tool simply because they offer less testing capabilities, for the average user or the professional, a digital multimeter is the best option. These devices are more accurate, can carry out a wider range of measurements, and are easier to read.
What are common problems with multimeters?
Since multimeters are powered by batteries, usually a 9-volt battery, one of the most common reasons for your device to not work properly is simply that the battery is dead. In this case, replacing the battery should restore your multimeter’s function. Another reason your multimeter might not work is a blown fuse in the device itself. The manufacturer’s instructions that came with your tool should cover how to inspect and replace the fuse if necessary. If that doesn’t seem to be the problem, check the probes for any signs of damage. Bent probes or probes with damaged wires will need to be replaced.
If none of those seem to be the problem, then it is possible that your multimeter has been damaged, especially if it has been dropped or treated roughly. In that case, you’ll need to buy a new one.
