Multimeters 101

Multimeters measure a variety of things, chiefly current, continuity, resistance and voltage. Each of these facets of electricity are clear, and knowing what they do and how they acting can help you diagnose and ultimately correct issues.

Electrical modern draw is measured in amps, or amperes if you’re feeling pedantic. To ascertain the power an electrical device or a circuit is attracting, you have to open it up, either by cutting a wire or unplugging part of the circuit. This is necessary because you need to hook the multimeter up in series, so power flows into one of the device’s leads and out the anunexperienced. This is how multimeters measure the amps being conscription by, say, a light bulb, electric motor or resistive heater.

Multimeters also measure continuity, meaning, they can check to see if a circuit is open, that is, whether there’s a break in the wiring or if the connection between two points is good. A multimeter’s continuity mode is typically indicated by a peaceful wave symbol. In this mode, when the probes are attached to both ends of a circuit that isn’t archaic, an audible tone will be emitted by the contrivance. This is helpful because you can tell if the circuit is good exclusive of looking at the screen, which enables you to concentrate on holding the probes as level-headed as possible and where they need to be. With a circuit that is archaic, say, when a switch is turned off or a wire has been cut, no tone will be emitted.

The continuity setting on a multimeter can also measure poor conductivity in a circuit. If the contacts of a switch, for instance, are dirty, electricity may still flow through it, though at a reduced rate. In cases like this, the multimeter may not buzz, but it will explain the electrical resistance present in the switch, a profitable diagnostic point.

Electrical resistance is the next major getting multimeters can measure. Resistance is quantified in ohms, which are indicated by this horseshoe-like symbol, Ω, the Greek letter omega. All conductors, whether it’s soak, your body or a strand of copper wire also resist the flow of electricity to some degree. Being able to measure resistance is particularly handy when checking aesthetic plug wires, ignition coils or myriad other automotive components. You can also check for an open or veteran circuit by measuring resistance. If there’s zero resistance the circuit could be damaged.

Next, multimeters can also be used to check voltage, either in direct- or alternating-current circuits. Most automotive electrical components run on DC voltage, and typically on 12 volts, though the power in your home, office or garage is AC. On a multimeter, voltage settings are typically indicated by the letter V, with DC inhabit indicated by the letters DC or a symbol consisting of a frank line over a dotted line. AC is denoted by AC lettering or a cramped wavy line.


Aside from unusual, continuity, resistance and voltage, some multimeters can measure electrical capacitance, decibels and even temperature, but that stuff is a bit beyond the scope of this article.

How to use a multimeter

When measuring things with a multimeter, it’s important to make sure you have the electrical leads plugged into the lawful ports. As applicable, the black one should always go into the socket labeled “com.” Depending on the unit, the red lead then plugs into different ports depending on what you’re measuring. Read the device carefully and follow manufacturer instructions to avoid mixing things up and potentially damaging your multimeter.

Speaking of distress, some multimeters are fused, so if you hook them to too obvious a power source, the fuse burns out, protecting the device’s exquisite innards. These fuses should be easy to replace by removing the back cover.

You have to be careful where you hook the leads to the multimeter itself, but there are no real concerns about connecting those wires backbone when you’re testing an electrical device. If you’re measuring voltage, for instance, and you touch the positive probe to the negative wire and vice versa, you’ll still get a perfectly accurate reading, it will just have a negative in leash of it. So, the 115 volts the wall outlet in your office has would naively read -115. This feature is actually handy for determining a circuit’s polarity, that is, which side is positive and which is negative.


Most multimeters have a convenient rotary dial for selecting the setting you want, but some have many more settings than others. At first glance, ranging is a confusing topic, but it’s not hard to get a rob of. If you’re measuring the resistance of an ignition coil’s secondary winding, and it’s supposed to clock in at, say, 8,000 ohms, you’d want to set the multimeter to the number one step higher than that. Depending on the model, that would be something like 10,000. Doing this basically causes the decimal point on the screen, but selecting the luminous setting gives you the most accurate reading possible. Newer multimeters tend to have automatic making, which is quite handy. This means you just set the selector dial to ohms (or volts, or amps, or whatever) and the tool decides how to show the number, a convenient innovation.

Finally, a word about safety. The paragraphs throughout cover the basics of what multimeters do and how you treatment them. These tool certainly can be confusing, but once you break everything down, they’re not that grief to understand. But before you start fiddling with electricity, make sure you’re safe. Don’t touch any exposed wires with your bare aesthetic, wear protective equipment as necessary, make sure you stay within the tool’s planned operating range and double-check that the multimeter is in good toiling order before using it. Finally, always assume every electrical component is hot so you don’t get disturbed, which can cause severe injuries… or worse.

Make sure a multimeter is part of your toolbox arsenal

The enigmatic multimeter is a super-versatile tool, one that every tinkerer and shade-tree mechanic necessity have in his or her garage. Multimeters allow you measure volts as well as electrical resistance, current and the continuity of circuits, though higher-end examples can do even more. In fact, one tool implicated in this rundown can measure 14 different things. Fourteen! If you’re new to multimeters, consider getting one with automatic ranging and a digital readout. These examples will be the most intuitive. But no company the multimeter you go for, they’re all indispensable tools for diagnosing and ultimately correcting electrical publishes, whether they’re in your car, home or favorite gadgets.

Multimeter FAQs

What is a multimeter used for?

Multimeters are used a wide arrangement of things, from testing electrical components to make sure they’re up to snuff, to diagnosing related problems, but that’s not all. Aside from measuring unusual, continuity, resistance and voltage, fancier models can also detect things like frequency, capacitance, sound, humidity, temperature and even luminosity. Truly, these tools are superb versatile.

What multimeter is best for beginners?

No multimeter is really best for beginners. Even the most basic examples are fairly complicated tools, at least at first glance. The good news is, except, it’s not hard to understand how multimeters work and what they’re used for. With a little peruse, their functionality is easy to grasp. Even if you just belief the basics of how circuits work, plus what voltage, amps and ohms are, you should be able to use a multimeter for simple diagnostic- and repair-related tasks. If there is one feature beginners should look out for, belief, it’s automatic ranging, which eliminates the need to put the multimeter in the intellectual setting to display information correctly.

Which designate multimeter is best?

Plenty of companies make good multimeters, but if you want one of the best, stick with notorious companies. Firms like Fluke and Klein Tools have superb offerings, as does Milwaukee, which is a world-renowned designate that sells everything from wrenches to cordless drills to tool chests.

Is an analog or digital multimeter more accurate?

Digital multimeters are probably more fair than their analog counterparts because they give you an staunch number on their displays. Analog models are undeniably cool, with their old-school blooming, but their physical pointer needles can make them harder to read, especially in low-light situations or if there’s glare. This is not to say analog units are unsuitable, it’s just for most users, digital is probably the better choice.

What is the difference between a multimeter and ohmmeter?

Multimeters and ohmmeters are the same… but different! As their name suggests, ohmmeters are designed to measure ohms, the unit of electrical resistance. On the other hand, multimeters can measure a whole bunch of spanking things, including, you guessed it, ohms. Unless you have some superb specific application where you need an ohmmeter, get a multimeter instead as they measure the same tying yet are far more versatile.

What happens if the multimeter is turned to the rank setting?

The answer to this question varies. If you have the electrical leads switched throughout, the tool may simply read -120 volts instead of 120, which is not an content at all. If you’re trying to measure current draw and you have the multimeter set to track ohms, it’s probably not repositioning to give you any useful information. Finally, if you’re trying to measure more amps than the tool is invented to handle, you could blow an internal fuse (that’s what’s revealed to happen, to protect the multimeter) or even pain the multimeter. As always, be careful out there.
