How to choose your multimeter

Because a multimeter is supposed to measure several electrical values, a certain accuracy and performance is expected from it. The following criteria will help you recognize a good multimeter.

#1 - The type of multimeters

There are two main types of multimeters: the digital multimeter and the analog multimeter.

  • The digital multimeter has a digital display, which means that the measurements are shown directly on the screen. Needless to say, it makes it easier to read the values. It is less expensive and has more features.
  • The analog multimeter has a dial with several types of graduations. A needle will indicate the value corresponding to the measured electrical unit. In practice, it is more reliable and accurate.

#2 - Precision

Because a multimeter is designed to measure electrical values, it must meet a requirement for accuracy so as not to distort interventions at the risk of creating major incidents. For this type of measuring device, accuracy refers to the margin of error, i.e. the difference between the actual value and the displayed value. The smaller this margin, the more accurate the multimeter.

#3 - The resolution

Similar to accuracy, resolution is the difference between two values displayed by the same multimeter and relating to the same unit. The smaller the difference, the better the resolution. Note that the resolution comes into play when two identical measurements are taken successively.

#4 - The effectiveness of the value

Multimeters, depending on their design, are more effective on DC or AC circuits:

  • The RMS or root mean square multimeter is recommended for measurements made on a direct current;
  • The TRMS or True RMS multimeter is indicated for alternating current.

#5 - The standard

For a multimeter to be put on the market, it must bear the mention of conformity with the IEC 601010 standard. However, depending on its category, it is matched to a specific type of use:

  • Category I: specific use on electronic equipment,
  • Category II: only usable on receivers (unsuitable for power supply circuits),
  • Category III: domestic use,
  • Category IV: professional use.

How to maintain a digital multimeter?

Digital models have electronic components that can fail after mishandling or over time. One of the most common failures is the death of your digital multimeter's internal fuse. To recognize the failure, simply try a measurement and your meter should read, "0.00″. This is a sign that the fuse has blown. This error was caused, 90% of the time, by a measurement beyond the limit of the tool. There is no way to know this at the time of the event.

So, you have to replace this component with a screwdriver. You need to remove the battery and unscrew the back panel. Once done, you will see the two fuses on their respective ports. Carefully remove the parts and replace them with new ones.

The different types of multimeters

To improve your knowledge of multimeters, it is useful to know that there are three main families: analog, digital and amperometric.


The analog model is easily recognizable since it is composed of a screen and a needle. The needle gives the measurement of a given electrical voltage by moving on a calibrated dial. This device offers a very good measurement accuracy and manages to challenge the more advanced models on this field. In practice, this device is the tool of choice for sound repair technicians. This is due to its wide measurement band that is superior to the latest generation models.



digital multimeter is made up of an LCD screen that allows it to display the measurement data you have made. To do this, it is equipped with a motherboard that automatically calculates the measurements, calibration, and broadcast them directly on the screen. It is easy to use, because you only need to read the information. This mechanism allows this tool to give very accurate measurements.

In addition, it has several features that allow you to quickly switch between measurement modes. Then, because of the electronic elements contained in the shell, the digital multimeters have more resistant structures. However, the only downside is that if the batteries fail you may get false information.



so-called amperometric device works like a digital multimeter. The only difference is that it is equipped with a clamp to check or measure the current flowing through a wire. It is used when the current on an element is too high, above 100 A. In addition, this clamp can be purchased as an accessory to a conventional multimeter



RMS or "Root Mean Square" measures the power of an electrical voltage as long as the wave is flat. To give you the measure, it identifies only the peaks in its calculations.

So, if you are often faced with a system consisting of direct current, the type of device equipped with this technology is perfect.


The TRMS, the true value, is used in most digital devices. It is a calculation mode recognized for its accuracy and reliability. In its calculation mode, it looks for peaks and variations and calculates them to find the exact value.

There are no disadvantages to using this mode.


A TRMS device will be more reliable in general. But as mentioned before, each electrician or engineer has his own needs.

Why buy a multimeter?

To test the operation of an electrical circuit

The multimeter allows you to test the electrical continuity between two points with its "ohmmeter" function. You can also measure the voltage of an electronic circuit with the Voltmeter option. As for the "ammeter" function of the device, it offers you the possibility of measuring the current intensity.

To have a multifunction tool

The multimeter mainly replaces three devices, namely the ammeter, the voltmeter and the ohmmeter. It can also measure the temperature of the circuit, the frequency of electrical signals or voltage peaks. All you have to do is select the function you need with a button on the multimeter. The most powerful ones can even be connected to a computer in order to have more details about the different values displayed.

To work safely

Handling the electrical circuit can be dangerous if you do not take the necessary precautions. The multimeter allows you to work in complete safety and avoids electrocution. In fact, it offers you the guarantee of working in the absence of electrical voltage.

To obtain a high accuracy

You can find digital multimeters that allow you to read the measurement directly on an LCD screen. The display of the measurement on this type of device is more accurate because of the absence of resistance. An analog multimeter, on the other hand, offers you the possibility of observing the oscillation of the current and measures the voltage present in an electric circuit.

To work efficiently

The multi-functional nature of this device reduces the number of tools required when working on an electrical circuit. In addition, it saves you time and is extremely easy to use. All you have to do is select the option for the measurement you want to make. Then you connect the red and black leads to the electrical circuit to be measured. There is no risk of making mistakes when using a multimeter.

To measure the intensity

If you have a digital multimeter, simply select the ammeter mode on the device. This is the function that will allow you to measure the current of an electronic component. Then, take the red rod, polarity plus, and put it in contact with the positive of the element to measure. Do the same with the black rod. Once connected, you will see the measurements appear on the screen. However, please make sure to locate the minus and the plus to have a measurement.
In the case of an analog model, you must manually choose the measurement modes. To do this, turn the central selector to the options you want. In this case, choose the numbers marked "A" or amperes.



a digital model, calibration is usually done automatically. The user will only have to start examining the element. In the case of analog multimeters, it is useful to perform calibrations regularly. The calibration procedure is a guarantee of the accuracy of the measurements taken. Moreover, during your test if the rods are not correctly put, you will have bad measurements. It is therefore recommended that DIYers use alligator clips to ensure that the parts are in good contact. Plus, using alligator clips will keep your hands free!

The equipment


it comes to handling electrical items, safety comes first. It's not just about your safety, but the integrity of the parts that make up the device. The wrong way of working could damage parts that were not damaged in the first place. So, always check that the equipment to be tested is turned off and not connected to an electrical outlet. Then, wearing anti-static wristbands will allow you to spare the other parts. Be sure to work on a bright, spacious table so that your movements are not impeded.

Find the neutral phase

Not all electronic components are well labeled. This makes it difficult to make the measurements properly. To find the neutral phase, you need a multimeter and check the voltage between the ground and phase potential. Normally, the measurement will be between 220v and more. If you opt for the neutral, you will have trouble, because in theory the voltage is less.

Decode the dial of an analog multimeter


probably noticed, there are several numbers engraved on the dial of the multimeter. So, you have 3 scales of measurements that we will detail below:

  • The top step of the podium is for checking the resistance "Ω."
  • The "DC" label is for direct current voltage
  • Third place goes to the "AC" label which is the alternating current.
  • Next, adjust the calibration of your device and begin your test. Read the measurement indicated by the needle and follow the formula below to perfect the information. If you have calibrated Rx10 and the measurement is 20 Ω, you have: 20 x 10 = 200 Ω.


What is the best multimeter?

The best multimeter depends on your needs and budget. Read our buying guide to find the best products available.

What is the best DIY multimeter?

An entry-level model will be the ideal weapon for DIY. Choosing a multimeter requires knowing important features and specifying a budget for your purchase. However, in our comparison we give you the steps to follow to find the model that suits you.

Why does my multimeter make a sound?

Some models available on the market make a sound when testing the resistance of an electronic element. This is normal. But if this is not your case, try to test the voltages and if it works and you can't get a resistance measurement; it means that your device is defective. As a last resort, check the state of your fuses if they were not damaged.

My multimeter shows the number 1?

This is an error in the voltmeter mode of your device. This number tells you that you have calibrated your device incorrectly. This often happens when you don't know the range of the voltage you need to monitor. To correct this problem, please choose a higher rating until the meter stops displaying this information.

Why does my Fluke multimeter display "OL"?

This is an indication of infinite resistance. It tells you that you have measured a resistance greater than your calibration.
