Multimeters Buying Guide

What are multimeters?

The multimeter is a hand-held device with many functions for measuring various aspects of electricity.

Such an instrument can be used to measure the current, voltage, or resistance of an electrical circuit. But these are just the basic functions of the multimeter.

Specialized models are available that, thanks to advanced options, allow you to measure microamperes, decibels, rpm, and even temperature and humidity.

Most multimeters are said to offer accuracy in the range of +/- 2%, which guarantees you accurate readings quickly and easily. With the help of such a device, you can easily detect any electrical malfunction in all your electrical installations and appliances.

However, in addition to detecting electrical faults and damaged connections in various appliances, circuits, power supplies, and wiring, the multimeter can also be used to troubleshoot problems.

With the multimeter, you could check how well the current flows through the circuit, as well as determine the level of resistance and voltage in the same circuit. In addition, you could check the inductance of the winding, the 12-volt contact in your car, or the quality of the power supply in any electrical circuit.

Whatever your goals, if you interact with electricity, the multimeter is your must-have.

It could save you a lot of money that an electrician will take from you just to say that there is a “fault” in the electrical circuit – something you can find by yourself with the use of a multimeter.

If you still think that these tools are intended for professional use only, you are definitely wrong.

If you prefer to deal with the faults in your home yourself, a multimeter will become a mandatory part of your tools.

Whether it is the capacity of the wiring or the battery of your car, with the help of the multimeter you will get the necessary information quickly, accurately, and safely.

What types of multimeters are there?

Of course, there are different types of multimeters to serve the needs of anyone who needs such a tool.

In its diversity, however, the main division between these devices is analog and digital.

Analog multimeter

This is the most classic type of multimeter. It works thanks to a coil wound around a drum placed between two permanent magnets.

The drum is connected by an arrow that moves on the scale depending on how the winding reacts to the magnetic field of the current and that of the permanent magnets.

What is special about these models is that reading the recorded data can be more complicated compared to a digital multimeter. However, many professionals prefer to work with such a tool in some more sensitive measurements.

Analog multimeters do not have such a wide range of measurements and are also larger and more expensive, but on the other hand, they work extremely simply and this allows more direct monitoring of the variability of the measured values.

Digital multimeter

The digital multimeter is the most popular and easily accessible type of multimeter.

These models have a screen on which the desired measurements are reported depending on the selected option.

Digital multimeters have a wider application, as they can measure not only current, voltage and resistance as analog ones, but also have more functions for additional electrical measurements such as temperature and humidity.

Although considered to be much more accurate and reliable than analog ones, digital multimeters may take longer to stabilize before receiving reported data. In addition, they deprive the user of the opportunity to directly monitor changes in the electrical system.

This type of multimeter is generally more expensive than its analog rivals, but on the other hand, it is easy to use, can store measurements automatically, and is famous for its high accuracy. Due to their affordable use, most multimeters on the market are of this type.

In turn, digital multimeters are divided into three main types, which we will also introduce to you.

Fluke multimeter

These digital multimeters can be designed with various functions, but are mainly used to calibrate voltage, current, and other electrical characteristics.

However, some devices come with functions for measuring humidity, pressure, temperature, and more.

Fluke digital multimeters are extremely small and easy to carry and use.

Multimeter with clamps

This type of multimeter is also known as a “clamp meter”.

The main feature of digital multimeters of this type is that they perform their measurements thanks to clamps that attach to the system.

These multimeters are mostly used to measure alternating current, but can also provide accurate data for other electrical characteristics.

However, their use is more special and since models with different types of metal in the clips are available, these digital multimeters are recommended to be used only by trained professionals.

Multimeter with auto range

These types of digital multimeters are extremely easy to use and that is why they are most suitable for enthusiasts who want to deal with electrical situations at home.

Once it is selected which of the current characteristics will be measured, the instrument itself adjusts the range in which the measurements are to be made. This makes working with these multimeters really simple and even enjoyable.

The convenience that this type of multimeter provides to its users is a more expensive one. On the other hand, the automatic range is precise and the accuracy of the instruments is in order, which still makes these multimeters extremely desirable.

Things you need to know before getting a multimeter

Now that you know the basic types of multimeters, we are sure that you know which one is most suitable for your purposes, as well as which one you will work with most easily and conveniently.

Now, however, we will introduce you to all the most important things to watch out for when choosing your future tool.

Voltage range

This characteristic is also known as the “tolerance range”.

Regardless of what you will be using your multimeter for, it is crucial to check the maximum voltage range of the instrument to make sure it is greater than the voltage range you will be measuring.

It is important to set the maximum expected amount of voltage that you will check because your multimeter must be set higher than it. Only in this way, it will be possible to have a tolerance for the instrument in the event of a fault.

For example, if you intend to check the 12-volt contact in your car, you must first set the range of your multimeter to 20 volts.

Resistance measurement

Absolutely every decent multimeter is expected to have an option to measure resistance.

Resistance measurement is especially useful in identifying breaks or faults in the electrical circuit.

When setting up your multimeter to collect this type of data, keep in mind that the fewer ohms the device reads, the less resistance there is in the electrical circuit.

Alternating current and direct current (AC/DC)

Each multimeter is expected to have options for reading both AC and DC. It is important that the current range of your multimeter is set to a larger value than you expect in the respective electrical circuit.

You need, of course, to be aware of what current is flowing in the circuit you want to check, and to consider the choice of your multimeter accordingly.

If you intend to use your multimeter primarily for computers and other devices of this type, then it would be best to invest in a tool with a stable DC range.

Either way, it all depends on your needs in the first place.

Additional features

Absolutely all multimeters are expected to be able to measure voltage, resistance, and current. Otherwise, it would not be reasonable to call them “multimeters”.

However, if you need a tool for different measurements, there are many multimeters on the market with different functions. Of course, the prices of the products increase depending on the extras included.

Many multimeters, for example, have additional clamps and test probes for specific work.

Multimeters with an auto-range also have a special function that adjusts their range depending on the circuit with which you interact.

The temperature probe allows you to measure the temperature of electronic devices, which can be especially useful in diagnosing subtle problems in the electrical circuit.

You can also get a special case (rubber), which is resistant to wear and protects your multimeter from the weather and water. With this special housing, you can protect your multimeter from sudden falls or shocks, as well as from any prolonged exposure to extreme cold or heat.

High-contrast LED screens are also available to allow you to collect read data even in visually impaired conditions due to darkness or other obstacles.

Some multimeters even have a built-in non-contact AV detector that allows you to get accurate AC voltage data without physical contact, minimizing potential risk situations.

Many of the more modern multimeters are also equipped with a special function for storing data or saving the maximum readings. This allows you to make quick inquiries without having to record your measurements by hand.

If you wish, you can even get a built-in stand for quick and easy work without having to use your hands.

As you can see, the range of additional features is really large, so it all comes down to your needs and preferences.

How to make the most of your multimeter?

Now that you know everything you need to know before you get a multimeter, we can now show you how to use your multimeter as fully and safely as possible.

The functionality and operability of analog and digital multimeters are generally similar.

In general, each instrument consists of two wires or probes (red and black) and three ports. The black wire is connected to the common port, while the red wire is connected to other ports depending on what is required for the specific measurement.

Once all the wires are connected, the knob in the center of the multimeter can be switched on so that it is possible to set the function required for the specific measurements.

For example, if we set the knob to measure DC with a range of 20 volts, then the multimeter will be able to read any voltage up to 20 volts. However, if you want to check the low voltage, you need to set the instrument knob to a range of 2 volts to 200 millivolts.

To get any reading, of course, it is necessary to touch each probe to the ends of the terminals of the respective components. All multimeters are carefully secured to optimize the operation of any devices and electrical circuits.

After touching each probe to the ends of the terminals, you will receive on your multimeter the data from the respective electrical system for which you have set up your device and which does not exceed the pre-set maximum range.

However, no matter how secure all the multimeters are, you still have to be extremely careful when working with them. Never touch the metal components to the terminals of the electrical system. Otherwise, you will get an electric shock.

In other words – be as resourceful as possible and beware.
