Basically a test tool that measures two or more electrical values, a digital multimeter is a serious upgrade to the old needle-based analog meter thanks to how it can do readings with greater accuracy, increased impedance and reliability. Combining the testing capabilities of a single task meter including the ohmmeter, ammeter and voltmeter, this type of device generally comes with advanced options as well as extra specialized features to accommodate the needs of technicians who use it. Now what makes a good quality multimeter?
Reliable Accuracy, Resolution and Digits
Some might argue that poor accuracy rating is not really a fatal flaw in a DIY electronic meter. We beg to disagree, since a multimeter with poor accuracy can fundamentally do little else than let you know if a circuit is working or not. If the device is not designed to be accurate, it may not even be able to do that at all. Another thing you wouldn’t want either is a meter that can’t be calibrated. Regular calibration ensures accuracy at all times.
The units that get top ratings in the best multimeter reviews boast reliable accuracy. Accuracy is the maximum allowed error limit for measurements. It is expressed as ± (% + number of least significant digit or LSD), and is given by two numbers, a relative error and absolute error. The relative error is expressed as a %, such as 0.5%, while absolute error is expressed in digits, such as 2 digits. Even educated engineers can neglect or downplay measurement error because of the number of digits the meter shows them. The absolute error loses its significance as the reading goes up, such as when comparing a 100.0 reading (0.2%) and a 900.0 reading 2 digits (0.022%). Accuracy specification is the maximum limit around the true value of the signal being measured. The least significant digit encapsulates the errors due to rounding off of values, analog digital converter (ADC) tolerances and offset noise.
Resolution refers to the smallest change in an input signal that can generate a corresponding change in the output signal. This element is expressed by the number of digits the meter can display. If you have a 3 ½ digital multimeter, that means it has 3 full digits that display values from 0 through 9, and one that displays either 1 or 0. The resolution is thus ±1,999 since the device displays positive and negative numbers up to 1,999. Today’s multimeters can be 4 ½ or 3 ½ digit models having a display range of ±19,999 or ±1,999. There are times when the resolution is referred to as ‘count’, which is the number the device can show prior to changing measurement ranges. Thus, a 19,999 or 20,000 display count multimeter is the same as a 4 ½ digit digital multimeter.
Accuracy is an entirely different thing from resolution. To illustrate, if you own a multimeter with 4 digits, this is equivalent to a resolution of 0.1%. However, if the accuracy of the same device is just 1%, then the last digit has no use. Bear in mind that if you need to differentiate between two circuits, with one working fine and the other working poorly, especially for electronics repair, then you’ll have to make sure your multimeter offers a superb level of accuracy.
Suitable form factor, true RMS converter
There was a time when only serious engineers used benchtop meters while handheld meters were confined to field work use. This has changed readily with the advances in technology that have made modern handheld models at par or even better than older benchtop meters, making them popular among most do-it-yourselfers. Benchtop models can be extra pricey but if you want the best in your devices, they make good investments. Do steer clear of the cheaper units, since you would be better off purchasing a top rated handheld meter. A bench meter offers quadruple-wire measuring ability, a superior technique for reading resistance thanks to how the resistance of the measuring wires themselves do not interfere with the measurements. A regular 2-wire measurement can have contact and wire resistances that can hamper the performance of some measurements, specifically with inferior quality resistors.
Look for true-RMS models, which offer true RMS values. True RMS values do not just signify the absolute value average of the curve, which is functional only with sinusoidal waveforms and not for nonlinear waveforms that are more complicated. Typically, only models beyond $100 offer true RMS capability. They can measure both sinusoidal and nonsinusoidal AC waveforms accurately. Sinusoidal or sine waves present purity and no distortion, with symmetrical transitions between valleys and peaks. Nonsinusoidal waves are characterized by irregular, distorted patterns in the form of sawtooths, triangles, pulse trains, spikes, squares and other angular or ragged waves.
Useful features and safety
In addition to the basic measurement functions, some multimeters are equipped with advanced functions that make them useful for special applications and needs especially for electronics repair and for computer repair technicians. These include: autoranging; USB interface; a stable stand; touch-hold; graphic display for showing AC measurements in real time; data logging software for convenient monitoring and documentation of measured data; low pass filter for motor drive troubleshooting; low impedance mode that prevents ghost or induced voltages during measurements; and offset compensation or smart ohm for resistance testing using 2 different applied currents
The unit should be protected against common electrical hazards. Think about the applications and environment the instrument will be used in to ensure you have the perfect device for your needs. For instance, when subjected to high current, a low-quality unit may explode and catch fire and the entire unit might melt within the first 30 seconds. A better quality unit would suffer no damage at all during the first 30 seconds. The internal fuse would break if you sustain the high current longer, but even if you have the device in your hand, no physical damage would occur that can cause user injury or hazardous contact with electric energy.

The uses of a multimeter
Combining the testing capabilities of single-functionality meters including the ohmmeter, ammeter and voltmeter, the digital multimeter is a test tool that replaces the needle-based analog meter easily thanks to its ability to measure with more reliable accuracy plus increased impedance. The multimeter measures AC or DC voltages, continuity of electrical components and resistance, along with small quantities of currents in circuits. It allows you to find out whether voltage is present on a circuit so you can perform diverse tasks. Technicians in the electronic/electrical industries use a digital multimeter as a diagnostic tool.
Parts of a standard multimeter
The display lets you view measurement readings and is where measurement readouts can be viewed. Typically, it comes with four digits and also has the ability to display a negative sign. Some models come with backlit displays that facilitate viewing of values in poorly lit conditions.
The selector knob, dial or rotary switch enables you to select different primary measurement values, whether amps, volts or ohms. The dial has arc-shaped scales visible through its window, along with a pointer that indicates the values read from the scale, which are the ranges of magnitude. The meter dial face can feature arc-shaped marks of different colors that indicate each scale, so there will be different values. There may also be a wider mirror-like surface shaped like the scales. This mirror-like surface reduces parallax viewing error by ensuring that the pointer is lined up with its reflection prior to the reading of the value indicated by the pointer. This can appear as a wide gray strip between the black and red scales. The selector knob or switch lets you change the function from amps to ohms to volts. It also enables you to change the scale of the instrument. Multiple ranges are presented by the different functions, making it essential that both are correctly set to prevent damaging the device or causing operator injury. Some meters feature an OFF position on the selector switch but others come with a separate switch for turning the instrument off. When the device is not being used or to be stored, make sure it’s switched off. The different buttons on the instrument allow you to select different functions, with options varying across different brands and models.
The input jacks are where the test leads or probes are inserted on the front of the multimeter. Test probes are flexible insulated wires that are red and black, serving as the conductor between the device and the item being tested. Almost always connected to the negative (-) or ground of a circuit is the common or black COM probe. However, there is no difference between a red and a black probe except in the color. When measuring large currents, the special port used is 10A. The red probe is typically plugged into the mAVΩ port, which enables the measurement of resistance (Ω), voltage (V) and current (up to 200 mA). On the end of the probes is a banana-type connector that plugs into the multimeter. Any probe with a banana plug will work with a multimeter so different types of probes can be used with the device.
The test leads or probes can be of various types: banana to alligator clips leads are suitable for connecting to large pins or wires on a breadboard. They are perfect for doing longer term tests where there’s no need to hold the probes in place as you manipulate the circuit. Banana to IC hook types are suitable for smaller and legs of ICs. Banana to test probes are easy and cheap to replace when broken. Banana to tweezer type probes are useful for testing SMD components.
Some common tests using the multimeter
A multimeter is used to measure resistance. The test for resistance should be performed when no current is present. Make sure to unplug the device or switch the circuit breaker off prior to attempting to do the test. In a circuit, the resistance denotes how much the flow of current is impeded. It is a necessary element for the generation of heat in various heating elements such as those in a hair dryer, electric oven, dryer or stove. To know if a device is indeed functioning properly, it is necessary to test for the proper resistance rating. The multimeter should be set to the ohm setting to carry out resistance testing.
The difference between two points in the potential of electrons is called the voltage. A difference in potential occurs when the accumulation or concentration of electrons in one point is greater than in the other point. If a wire is used to connect those two points to each other, the electrons will flow from one point to the other until the electron potential becomes equal. This movement of the electrons from one point to another is referred to as a direct current of electricity. When measuring the voltage of a battery, the range selector switch is set to any of the DCV positions.
The test for continuity is also done when current is not present. It should also be performed with the main circuit breaker switched off or the item being tested is unplugged. A continuity test is done to find out whether a circuit is open or closed. The multimeter also has to be set to the ohm setting. Even when the probes are not in contact with anything, the multimeter will read infinity. This means the circuit is open and therefore unable to conduct current. The reading changes to zero when the probes are touched together, indicating that the circuit is closed and is able to conduct current. When each probe is touched to one of the terminals and the reading changes to zero, it indicates the presence of continuity.
Testing for ground can also only be carried out when current is not present. The device to be tested should be unplugged and the main circuit breaker turned off before you attempt to test ground fault. Ground fault testing is performed to determine if current is not appropriately channeled from a circuit. If left unchecked, ground fault presents a potentially dangerous electrical shock hazard as well as a cause for the electrical device to get broken. Ground fault testing, like all other tests done with a multimeter, is carried out at ohm setting.
