Features To Consider With Multimeters
When searching for the best multimeter, you must consider the design. It needs to be compact for easy portability as well as ergonomic. If there is a built-in stand for hands-free use, this is also an excellent design feature, as it will make it safer to use and easier to read.
Large and easy-to-read digital displays with a backlit screen mean you can use your multimeter in an environment, whether the light is strong or weak. A large screen will also make it easy to read so there is no guesswork over the AC voltage and current or resistance-capacitance readings, providing more accuracy that enhances safety and guarantees a job well done.
Auto Vs Manual Ranging
Automatic ranging is a highly useful feature that will save time and energy when attempting to check readings for your electrical circuits. As the name suggests, it is automatic, and therefore will identify the range for you compared to manually selecting the voltage range. Automatic ranging can also provide better accuracy, and any of the multimeters that come with automatic ranging will have plenty of other features, too. Despite this, they will also offer manual settings too if you want the best of both worlds, whereas solely manual multimeters will only allow manual range application.
Accuracy is a must when it comes to selecting a multimeter best suited to your needs. For high accuracy, a digital system is preferred, but even these can have some issues when it comes to presenting the correct readouts. To overcome this, you're best investing a little more than you might expect, especially for professional needs.
All multimeters come with a specific current range that you must not exceed if you want to prevent accidents and short circuits. Again, this will come down to what you need the digital multimeter for. If you are working with home circuits, the standard multimeter current range should be enough. However, for industrial demands, you will need to consider something more suitable and capable of handling high current readings.
The more measurements you can select, the more versatile your multimeter is. A standard multimeter will cover the basic electrical needs, such as measuring AC/DC voltage, resistance, and current. However, for more demanding electrician jobs, including those that require an HVAC multimeter, you should consider looking at more comprehensive models. These will be able to everything a standard model can do, but also include functions such as temperature, continuity, capacitance, frequency, and more.
Input impedance is useful for measuring more sensitive electronic equipment. This demonstrates how good your multimeter is. Look for anything around 1MOhm if you are concerned about purchasing the best multimeter for professional jobs. Of course, casual users may not need the very best, but it's still important to think about what inputs are available.
Safety features are essential when you are working with electronics whether they are high voltages or not. The best multimeters come with a wide range of safety features and ratings to protect you, your multimeter, and your circuits from damage or injury. The most obvious safety feature is a rubber case which nullifies the current and prevents accidental electrocution. There are also other features that will guarantee reliable protection, such as CAT III and CAT IV ratings, as well as automatic shut off systems and overload protection. Arguably safety features are the most crucial thing to consider, so don't neglect to research these properly.
Ease Of Use
The easier your multimeter is to use, the less chance that something will go wrong. Ease of use can come in a range of forms, including the size and design, but also the quality of the parts, dial vs. button design, and the variety of measurement options. For beginners, stick to something that is easy to get the hang of immediately to minimize potential problems when looking at types of multimeters that you may want to purchase.
Any extra features that can improve your multimeter experience are definitely something you must consider. Aside from just purchasing a multimeter, there is a range of other accessories you can buy, too. These include a carry case that will protect your multimeter from damage while in transit or even from dust particles affecting the performance if you don't use it often. To save money, you should also make sure that your multimeter comes with test probes. Doing so will also allow you to try it out immediately rather than wait for them to arrive.
Types Of Multimeters
Analog multimeters are not as common as they were, especially considering how accurate the best digital multimeters are. They use a pointer to display current, voltage, or resistance. While useful, they are not as comprehensive as digital multimeters.
Digital multimeters are the best choice when looking for the best multimeter to buy. They come with a wide range of functions and deliver clear and accurate readings, and you can also use them for non-contact measurements to additional safety.
Q: What are multimeters used for?
The best multimeters can cover a wide range of needs. But primarily, digital multimeters are most effective for measuring at least two electrical values. Typically, you will see electrical technicians using them, but as the years have progressed, anyone who needs a multimeter can purchase one as they progressed from analog multimeters into something more user-friendly.
Even if you are not an electrician or even someone who regularly works with electrical circuits, a multimeter will help you identify and diagnose electrical issues. This is beneficial for the home, as it means you can work out what is wrong with your electrical circuits without needing to call an electrician out, saving you money and making you feel you know what you're doing.
Q: How do multimeters work?
It makes sense that anybody who wants to purchase one of the best digital multimeters should understand how they work before doing so. Understandably, anything related to electricity and circuits can be quite intimidating, so we'll try to simplify it as much as possible.
There are three meters included with a multimeter (hence the multi). These are an Ammeter, Ohmmeter, and a Voltmeter. These measure current, resistance, and voltage respectively. Rather than have one instrument for each, the best multimeters combine all three together to provide a convenient all-in-one gadget for your electrical needs.
You can also measure current and voltage in two different ways: alternating current and direct current. You have likely heard of these before, referred to as AC/DC. While most household sockets and appliances use AC, there are some which rely on DC voltage, and this gives you broader versatility for measuring and identifying electrical issues wherever you are.
Q: What is the easiest multimeter to use?
Honestly, there is no such thing as the easiest multimeter to use. Some may consider multimeters with the most basic setup to be the easiest, but if you are a professional electrician, these basic models are not much use to you as you won't be able to complete your work effectively.
The easiest multimeter to use is the one you have studied and practiced using. That being said, once you get the hang of one multimeter, most others are simple enough, and there are only slight differences in how you use it, such as selecting the function (buttons vs. dial), or what it can do.
If you are buying a multimeter solely for home use, then the most basic model is the best place to start, and you should only consider investing in a better (but potentially more complicated) model if you feel it is worth it.
Q: Are multimeters dangerous?
There is always the risk of danger when working with electrical systems, especially if you cannot deactivate the current prior to testing, which is what you need to do when using a multimeter. However, if you know how to use a multimeter correctly, you should not have any trouble, and you can use it safely.
Despite this, there are still many ways in which digital multimeters can be dangerous. The most common issue is when working with live circuits and placing the Test Leads in an incorrect place. This could cause a short circuit, and if bare skin is touching the wrong place, then there's a risk you will be electrocuted.
There is also the risk of hand-to-hand shock, and this is common when using an old or damaged multimeter. Because of this, it's vital that you take no chances when using your multimeter and always read the instruction manual to make sure you do not operate it incorrectly or dangerously.
Q: Do I need a true RMS multimeter?
A True RMS multimeter will provide more accurate readings if your circuit current is distorted. By using one of these multimeters compared to an Average RMS model, you can minimize errors and understand any issues more confidently. Whether you are a professional or hobbyist, they can save you time and effort while also making you more adept at recognizing problems when they arise.
They can be more expensive compared to ARMS alternatives, so if you just want a multimeter to save you from calling an electrician with every issue, you might not need one right now. If you plan on using your multimeter a lot, then true RMS is the best type of multimeter to purchase.
Q: How do you use a multimeter?
Understanding how to use a multimeter is crucial for your safety and to protect the circuits around the house, building, or your vehicle. Before doing anything, you should familiarize yourself with all the multimeter features and functions. This will include reading the display, selecting different settings, and understanding where to attach the test cables.
The best way to avoid injuring yourself is to measure the voltage of a standard AA battery. On the multimeter select the range (or let the auto-ranging do it for you) and hold the leads to both ends of the battery. If it works, it should show you the correct voltage. You can confirm this on the battery packaging.
As you will mostly use your multimeter to measure voltage, current, resistance, and continuity, you can work through the settings in a safe environment. Some brands may operate slightly differently to others, so you can follow the instruction manual to ensure you do it correctly.
