How to Choose the Best Multimeter
In this section of our multi-meter review, we’re going to show you some of the things that you should look at when choosing a multi-meter. While we’ll be covering the various features that can come with a meter, it doesn’t mean that you’ll need all of the bells and whistles on your multi-meter.
Before we get started, you’ll need to know your meter’s intended purpose so that you can choose the right tool for the job. By understanding the intended use, you’ll also be able to save money on your multi-meter by selecting a device that only has the features that you require for your job.
While you’ll be able to choose a fancy multi-meter, there’s little sense in doing so if you’ll only be using a couple of the primary features.
Here are some features to consider when choosing a multi-meter.
1. Digital Multimeter or Analog Multimeters
Before you purchase a multimeter, you’ll need to determine whether you’d like to have a digital interface or an analog interface. While both of these interfaces work, most people have a strong preference for one or the other.
Some people prefer to have an analog interface instead of the digital interface because they believe that it allows them to have better readouts and visualize the changing trends of the electrical currents.
Like a speedometer, you’ll be able to see the ‘pointer’ change its location as there are changes in the electrical currents. When you’re using an analog interface, you’ll be able to see these spikes because the ‘pointer’ will jump around. However, with a digital interface, you won’t be able to see these random changes as clearly because the numbers will change so quickly that you won’t be able to read the numbers.
On the other hand, many people prefer to use the digital interface because it allows them to accurately read the minor changes in amps, voltage and ohms. When you’re using an analog interface, you may not see the lower input impedance because the higher the input, the easier it is to see the changes and read them out with an analog interface.
However, with the digital interface, you won’t have any issues with readouts for micro-changes because the digital multimeters are excellent at being sensitive to even the smallest changes in electrical currents.
While the choice between digital and analog multimeters is yours to make, we recommend that you choose a digital multimeter that comes with a bar graph display to digitally record the micro changes while being able to visualize the larger spikes with a digital bar graph.
2. Type of Electrical Current (AC/DC)
When you’re using a multi-meter, you’ll need to be aware of the type of electrical currents that you’re trying to measure. There are two types of electrical currents that you can measure with a multi-meter: the Alternating Currents (AC) and the Direct Current (DC).
- Alternating Currents (AC) – The alternating current refers to the electricity that is continuously flowing back and forth in both directions. The alternating currents can be found in power sources for your home and household appliances such as your refrigerator, dishwasher and toasters.
- Direct Current (DC) – The direct current refers to the electrical currents that are continuously flowing in one direction. You’ll find DC currents in almost all handheld devices, battery-powered items, hybrid cars or even flat-screen TVs.
While most meters will measure both of these currents, not all of them have this ability. You’ll need to be careful when choosing your multi-meter to ensure that it’s able to measure the correct electric currents.
3. Auto Ranging or Manual Ranging
While choosing a multimeter for your job, you’ll need to determine if you’d like to have automatic ranging or manual ranging. This feature will come down to your preferences; however, it’s easier to use the auto-ranging multimeters.
With an auto-ranging multi-meter, you won’t need to input the ranges before you begin testing. This is because the multimeter is designed to recognize the type of project that you’re working on and output the right measurements.
If you choose a manual ranging multi-meter, you’ll need to know a lot more information about your projects such as the resistance, voltage, capacity and other values. You’ll need to use this information to set the right ranges for testing manually, or else you won’t be able to get any readout from your machine.
4. Choose the Measurements
You’ll also need to be mindful of what you’re trying to measure before you buy a multimeter. Almost all multimeters can measure the basics such as voltage, electrical currents and resistance. These measurements can be calculated by the volts, amps and ohms.
However, unless you have a higher-end multimeter, you may not have the ability to take other measurements. Some of the more expensive multimeters will measure temperatures, continuity, frequencies, resistance, and capacitance. While you may not need a tool that can find these measurements, you’ll need to know what you’ll use the multimeter for before you purchase so that you can find a device that fits your needs.
5. Select the Inputs
With the cheaper multimeters, you’ll likely only have two ports that can be used to attach your probes to the machine. These ports are often referred to as the common and the input. On these devices, the input will be used to measure all the currents, which can be dangerous if the levels of electricity are quite different.
When you’re using a multimeter that only has one port for the input, you’ll need to pay close attention to the settings that you’re using, so that you don’t measure a current that’s too powerful for the machine and cause damage to the multimeter.
If you choose a higher-quality multimeter, the machine should come equipped with multiple ports that can be used for different measurements. One input may be used for the currents, while the other input is used to handle the resistance and voltage measurements. This is safer than using a single input machine because it helps eliminate the chances of accidents happening while you use the meter for testing.
6. Other Multimeter Features
There are many things that you should look for when choosing the right multimeter; however, there are additional features that you may want. While these features may not be essential, they can make your machine last longer and make it easier for you to operate your multimeter.
Here are some additional features that you may want to consider.
- Probes – When choosing a multimeter, you’ll want to ensure that you select the right probes. Some common types of probes include Alligator Clips, IC Hooks, Tweezers, and Test Probes. You’ll also want to make sure that the handles come with protective bars that prevent your fingers from touching the metal probes and shocking yourself.
- Measurement Holds – If you’re using a digital multimeter, you may want the measurement hold feature, which allows you to test the currents and then press the ‘hold’ button, and that specific measurement will be frozen on the screen. This will help you remember the readout numbers accurately throughout your testing.
- Measurement Ranges – You’ll also want to pay attention to the range of your multimeter. If you’ve purchased a meter meant for residential outlets, it may not have the range for higher power outlets. If you’ll be using your multimeter for a variety of uses, then it’s best to choose a machine that has a wide measurement range.
- Size and Build – When it comes to multimeters, there are many sizes that you can choose. You could go with a larger heavy-duty machine or a pocket meter for quick testing. You’ll also want to pay attention to the multimeter’s build to ensure that it’s durable and comes with a protective casing to protect it from falls.
- Sound Alerts – Some multimeters come with sound which alerts you when the machine is sensing some electrical currents. This is a nice feature to have if you’re quickly testing a wall outlet or some batteries.
- Built-in Lights – There’s nothing worse than trying to figure out electrical issues in the dark. By working in the dark, you not only complicate your project, but it can be dangerous if you’re working with open wiring. One way to prevent this is by choosing a multimeter that comes with a built-in LED light that can be used to illuminate your workspace.
- Price Range – If you’re looking for the best multimeter, you’ll notice that there’s a wide price range for these tools. While there’s a wide range of prices, it doesn’t mean that you won’t be able to find a multimeter that’s suited for your job. We recommend setting a budget so that you can find the best multimeter within your price range.
While there may be other features that you’d like to have in your multimeter, these are some of the most common and useful features that you’ll be able to find equipped on a meter.
7. Choose a Warranty
As with any large purchase, you’ll want to ensure that you get a warranty to protect yourself if there’s an issue with your product. Since multimeters can cost hundreds of dollars, it’s wise to choose a brand that offers an extensive warranty on their products and tools.
