What is a Multimeter?
A multimeter is an electronic measuring device that takes multiple types of measurement in one device. It prevents the need for having separate meters as it combines the functions of the best voltmeter, ohmmeter and ammeter together.
A standard multimeter has the ability to measure voltage, current and resistance all in one device. Digital multimeters display the measured value with numerals, and some may provide a bar of length to represent the value measured.
These types are much more common, but some may prefer analog devices in situations where the measured value changes rapidly. Multimeters are used to troubleshoot electrical problems in a variety of industrial and residential applications.
How to Use a Multimeter
The voltage refers to the electrical potential of the device (the electric pressure in a circuit), and it is measure in volts (V). The voltage is measured with the voltmeter function, so the multimeter must first be switched to the volt setting (denoted with “V”).
Locate the test leads, and connect them to the meter. The red lead should be connected to the red input terminal (labeled “VΩ”), and the black lead should be connected to the common terminal (labeled “COM”).
The red lead is attached to the terminal with higher potential with the black lead to the one with lower potential. Once the leads have been connected correctly, you can measure the voltage with the multimeter as accurately as the best voltage meter.
Measuring current is measuring the flow of change in electricity in a circuit, and it is provided in amps. Measuring current is slightly more complicated than measuring voltage because you have to do so in a series.
You must place the meter between the flow of current, and this requires interrupting the power connection. To begin, set the multimeter to the ammeter function (labeled “A”). Connect the red lead to the terminal labeled “300mA” and the black to the common terminal (“COM”).
After properly connecting the leads, attach the device to the circuit that must be broken. Attach the meter in series between the open points to get amp readings. After measuring current, you must always switch the unit off or back to the volt setting before taking a different electrical measurement. Failing to do so may ground through the meter which may blow the fuse.
Resistance refers to the level at which an electric current is opposed through an electrical conductor. It is measured in ohms denoted as “Ω.” To begin, disconnect the power and wiring of the circuit that is to be measured in order to prevent exposure to potential hazards.
Turn the meter to the ohms (Ω) setting, connect the red lead to the “VΩ” terminal and connect the black lead to the common (COM) terminal. The display should show “OL” to denote overload. To measure the resistance of the circuit, connect both the red and black leads to the circuit. You will then be able to acquire the ohms reading.
Factors to Consider When Purchasing a Multimeter
There are several brands to choose from when it comes to selecting the best digital multimeter. The most well-known brands are sought after for having built a reputation for producing quality tools that offer the best result. You should research different brands to become accustomed to the types of products they have available in addition to reading reviews of the best models.
Quality multimeters should have a sturdy build that can withstand drops and bumps, and they should have an expected lifespan on the longer end of the range. Some models are known to last longer, and some brands are known to constantly produce models that can endure more than many others.
Good devices will often be dust or waterproof, and they will be able to withstand various temperatures. Units above $100 will usually present better durability with components that are easier to adjust. They will also be made with better materials.
When considering the features of a multimeter, consider what the unit can measure and how well it does so. Standard units allow you to measure current, AC/DC voltage and resistance. Additional features usually include auto-ranging, data storage, adjustable sample rating and triggering. Auto ranging makes the unit more flexible and allows you to choose a wide range of voltages. This feature is helpful for detecting malfunctioning wiring systems and computer issues, among other applications.

Continuity is useful for determining if a wire or circuit has a break, and some units respond better by providing more audible alerts. HVAC technicians should look for multimeters that allow temperature measurement, and these units often include K type measurements or IR thermometers.
The readings produced by your meter should be trustworthy in order to ensure the safest and most effective results. Calibration of a multimeter is important to ensure safely accurate readings. The accuracy of the unit is described as the maximum error limit considered acceptable for a reading.
It is expressed as ± (% of reading + the number of the least significant digit). This shows the accuracy as the maximum limit around the true value of the measured signal.
A multimeter with True RMS presents better precision, and it refers to the conversion of the AC signal data into the digital value given in the display. These units are more expensive to purchase, but they provide much better measurement. Meters with True RMS calculate accurately even upon encountering irregular waveforms such as square or sawtooth waves.
Reliability is an important component of any electronic device. You need the unit to be available to work whenever it is in use. When calculating data, reliability also refers to the ability to receive the same results with repeated trials.
This is essential for having an accurate device. You can compare models against one another to determine if one or both are relatively accurate or reliable when measuring current, voltage, resistance and frequency.
Different brands will have varying prices for their multimeter units, so it is best to research and look around in order to make selections within brands that have models in your budget range. The features you aim for in your unit will also affect how much you can expect to pay.
The cost can range from a mere $50 all the way up to over $400. Purchasing a multimeter that is not calibrated will allow you to buy one at a reduced price, but you compromise the benefit of set accuracy. Additionally, you would have to pay to have the unit calibrated annually.
For quality calibrated devices, you should expect to pay over $100 at the least. Most people search for handheld multimeters, and these are much more affordable compared to bench top models. Bench top models are much more expensive and usually cost up to $1,000.
Safety & Protection
Having a safe multimeter means you can depend on it to provide accurate data and safely take measurements. When you choose a unit, you should determine the CAT levels in which you plan to operate. Your multimeter should have a voltage rating higher than the maximum voltage you will test at each CAT level.
A higher voltage rating means a higher transient withstand rating within each CAT category. It is important to keep the category in mind when comparing voltage ratings in order to make sure you have the right tool for your tasks.
Ease of Use
One of the aspects of the best multimeters that is often overlooked is their ease of use. In addition to its capabilities and physical build, a unit should be simple to control without having to rely on supplementary information.

As a last step, take the chance to test meters out in person before purchase to get a real feel for how you may be able to use them.
Where Can I Buy a Multimeter?
Where you purchase your device may be just as important as the model you bring home. Many stores in your local area should have multimeters for sale, and this is helpful if you need a device as soon as possible.
The drawback to shopping this way is the fact that you may not be able to find the best cheap multimeter or the exact model you planned to buy as your local stores may not carry it. This is one of the reasons why it is usually better to order a multimeter online.
You will be able to find the device you want, and you can find a good cheap multimeter nearly anywhere. Buying on Amazon allows you to take advantage of discounts that you probably would not find elsewhere.
Making the Decision
The final choice in picking a quality multimeter lies in your hands. You should carefully look through digital multimeter reviews in order to become familiar with the features and functions they offer.
With a list of the features you need already in mind, match models that interest you with what you need in a multimeter based on how you expect to use the device. You must also use the information you find in reviews to compare various models against one another to determine which ones stand out above the others.
This will help you find models that match your needs, but you will be able to find the high quality models at the same time. If being able to use a dependable multimeter is a necessity in your line of business, get started selecting a model so you can put it in play as soon as possible.
