How we chose our selection of multimeters for electronics


There are dozens of companies that make multimeters. As such, separating the wheat from the chaff, in this case, was not easy. Ultimately – because electrical work can be downright dangerous and because the electricians we consulted recommended it to us – we have largely (but not exclusively) turned to the better-known and trusted brands.


Because these are sensitive electronic devices that could cause harm if not used properly, we haven’t given much weight to overly simplistic two-word reviews (“Works great. good ! “). Instead, when we looked at the reviews, we mostly focused on those that focused on particular aspects of each instrument. In the end, however, we still draw our own conclusions, although in this case, we have used licensed electricians for advice and assistance.


Accuracy depends on how closely the value displayed by the meter relates to the actual value of the thing being measured. The accuracy is usually measured in one of two ways: either the percentage of the range or the percentage of reading. Percentage reading is the most accurate mechanism since it is applied the same regardless of the measurement.


Electrical multimeters are like most other things in that you tend to get what you pay for. While a cheap multimeter can do a good job of providing accurate readings, you run the risk with some (not all) that if you drop it once it will be useless afterward. The multimeters we’ve chosen for this list are all well built and able to withstand shocks (to the extent possible, of course).


We believe that when your life is on the line, quality is important. So, there are a good number of high-end multimeters on our list. At the same time, when we find one that will hold up when our experts put it to the test, it will be on the list regardless of the price. Our only guiding principle with these important devices is that they are quality instruments that will not put the user at risk.


Features to look for in the best multimeters for electronics

Number of functions

Will, you only be measuring AC current or will you need to measure DC as well? Do you need a thermometer? Do you need to measure the capacity? The point is, there are dozens of different functions and we don’t have the space to list them all here. Suffice it to say, you need to determine in advance which ones you will need and then make sure your reader performs them.

Auto vs Manual Measuring Range

Most DIY enthusiasts will naturally (and wisely) gravitate towards auto range multimeters because they allow you to get your reading without having to know capacitance, voltage, resistance, and the like values ​​of the object you are testing. The automatic multimeter does all of this for you. A manual multimeter, by comparison, requires that you know the characteristics mentioned above and enter them by hand to get your measurement.


People tend to prefer analog multimeter displays over digital displays for the same reason they prefer analog clocks to digital clocks: context. With a traditional circular clock, you see the time, but you also get a feel for how much time is left before lunch or when to stop, and you see the hands moving. Whereas with a digital display you only get one number. With multimeters, many people prefer the analog display because it provides them with a real-time context that allows them to better understand or anticipate trends. Having said that, there are a lot of people who have no problem with digital signage.

Ease of Use

Most electricians will be able to work quickly with just about any multimeter on the market. If you are not a pro, however, you would be wise to spend some time familiarizing yourself with some basic electrical principles and terminology before you even start buying a multimeter. This will allow you to understand what you are looking at when shopping and find one that is easy for you to use.

Safety Features

You’re going to need to make sure you get a multimeter that has the correct CAT rating. In this case, “CAT” stands for “category” and there are 4 main categories ranging from CAT I (home electronics and the like) to CAT IV (utility level measurements). Overload protection, safety cut-off, proper voltage range, and reverse polarity are other safety features you will see in the best multimeters.


When it comes to something like an electronic multimeter, aesthetic considerations come second to functionality and safety. That said, design considerations do come into play if you usually work on construction sites. In this case, you want something that is easy to see. So bright yellow or orange are good color choices. Some multimeters designed for commercial electricians will also have corner bumpers to protect them in the event of a fall.

Additional Features

If you’re a handyman buying a multimeter to use around the house or in the car, chances are you don’t need a lot of special features. Commercial electricians, however, may want things like pressure, temperature, capacity, and frequency. Some high-end multimeters have graphic displays that provide real-time AC measurements. Others offer data logging capability.



What is a multimeter?

A multimeter is a standard diagnostic tool for electricians and other technicians who typically deal with electrical components or electric fields. Many DIY enthusiasts also use them when performing tasks around the house, like wiring, electrical circuits, etc. The electrical multimeter tests standard electrical values ​​such as voltage, current, resistance, and more.

Who should own a multimeter?

The vast majority of multimeters are owned by electricians, electrical engineers, and technicians such as those who work on HVAC systems. They are also popular with DIY enthusiasts who use them when installing light fixtures, ventilation fans, and the like. Professional electricians depend on multimeters the same way a professional carpenter relies on his tape measure and level. Inspired hobbyists should consider getting one with auto-ranging as it will greatly simplify the process.

What are some of the common electrical properties that a multimeter can determine?

Voltage – Voltage is generally defined as the amount of potential energy between two given points in an electrical circuit. There is a difference in charge between one point and the other and this difference is called “volts” (after Alessandro Volta who invented the chemical battery).

Current – Current is defined as the amount of charge flowing through a circuit during a given period of time. In the event of an electrical accident, it is not the voltage that kills people, but the current. The current is measured in amperes (amps) and it usually takes no more than 10 mA (10 mA) for a person to lose control of his muscles and as little as 1/10 of 1 ampere for only 2 seconds cause death. It is therefore crucial to obtain accurate current measurements.

Resistance – No one will be able to run as fast as if they were running on an open track. Why? Because they face a lot more resistance when running through the brush. It is essentially the same as electricity. A circuit with higher resistance has less current flowing through it than a circuit with low resistance. The resistance is typically expressed as “ohm” and represented by the Greek letter “omega” or “Ω”.

What is a real RMS multimeter?

A True Root Mean Square or True RMS multimeter is a type of multimeter that measures the level of alternating current (AC) or voltage. RMS suggests the effective level of alternating current as opposed to other types of multimeters designed to measure the average level of alternating current. RMS is used to calculate current or voltage levels when precise measurements are needed.
