The Best Multimeter for Electronics
A digital multimeter is a necessary tool for people who work with electronics. People who like to do electronics as a hobby also use digital multimeters. But there are different types of digital multimeters used for different things. For example, car mechanics and electricians might need a different digital multimeter than someone who just likes to do electronics as a hobby.
There are numerous varieties of digital multimeters. This is because they require various things from different people. So before you buy a digital multimeter, you need to know what you will use it for. If you are an electronics hobbyist, you need to look for a digital multimeter with certain specifications. For example, it should have the ability to measure voltage, current, and resistance.
What to Look for in a Digital Multimeter for Electronics Work
It is usually good to buy a “brand-name” digital multimeter. This is because well-known companies that make these meters always try to produce high-quality products. However, it is important to note that better quality usually means a higher price tag. Both electronics professionals and serious amateurs must get a good quality meter. Some of the more established digital multimeter brands are listed below (though this list is not exhaustive):
- Gossen Metrawatt
- Amprobe (owned by Fluke)
- BK Precision
Auto-Ranging or Manual-Ranging
- The digital multimeter can measure both AC voltage and DC voltage.
- The digital multimeter should measure AC and DC voltage up to 1000V. Measure millivolts (e.g., 200mV) to accurately measure lower voltages.
- For electronics work, the digital multimeter should measure from about 200Ω to 20MΩ.
- For both AC and DC ranges: the digital multimeter should be able to measure in both the minimal Amp range (µA) and also in the medium Amp range (mA) and extensive Amp range (A).
- The digital multimeter’s amperage measuring upper limit should be 10-20 amps.
- Cheaper multimeters often have a combined ‘VΩmA’ terminal. This is not recommended because it is unsafe. It is better if the current (µA / mA / A) terminals are separate from the voltage and resistance (VΩ) terminal.
To prevent the multimeter from changing the voltage across high resistance components, it should have an input impedance of at least 10MΩ.
Diode Measuring Function
Battery and Fuse Access
Some digital multimeters have a special door that opens to let you access the battery and the fuses.
Long Battery Life
Some digital multimeters (DMMs) have been created to use battery power more efficiently. DMMs are classified according to battery life into the following three categories:
- Best high-end DMMs: 1000 hr
- Good DMMs: 300 – 500 hr
- Poor DMMs: 100 hr or less
People who like to do electronics projects should try to find a DMM (digital multimeter) that has a battery life of 300 – 500 hours.
- There are two types of input jacks on digital multimeters:
1. A metal jacket with a split: These types of meters tend to wear out more quickly. However, some high-quality meters are designed to be hard-wearing and last long.
2. A solid metal jacket: These tend to be more expensive digital multimeters built to last longer.
- Shrouded input jacks on digital multimeters help keep you safe. This is because the metal contact is hidden, so you can’t accidentally touch it. Banana plugs on probes should also be shrouded for the same reason.
Capacitance Measuring Function
In general, the lower the capacitance measuring range of a digital multimeter (DMM), the better it is for electronics work:
- Less expensive DMMs will only measure capacitance down to the hundreds of microFarads.
- Medium-range DMMs can usually measure down to a few nanoFarads.
- Some high-end DMMs can measure capacitance in the range of picoFarads.
Remember that measuring capacitance with a digital multimeter is not very good. In fact, you can expect the meter to be only about 1-2% accurate.
Some meters have separate terminals for testing capacitors. This is okay for low voltage capacitors, but measuring high voltage capacitors with a regular meter can be dangerous. Higher-end DMMs do not have separate capacitor testing terminals because of this danger.
Relative Measurement Feature
This feature is found on some digital multimeters. It is helpful because it allows the meter to compensate for the internal resistance of the probes themselves (and their wires), which might skew readings slightly. Additionally, this feature can measure a change in voltage from a reference value.
This setting on the digital multimeter records the minimum and maximum values seen during a measurement.
This setting on the digital multimeter records the minimum and maximum values seen during a measurement.
This feature on digital multimeters will freeze the readings on the meter screen, so you don’t have to see them constantly. The Hold function will also keep the reading even after taking the probes off. There are two types of Hold functions that are available on digital multimeters today:
1. Auto-hold is a feature found in more expensive digital multimeters. This feature freezes the reading when the measurement is taken, which is usually signaled by a beep. This is the preferred option!
2. Manual-hold is found on less expensive multimeters. This means the operator has to push a button to freeze the reading when taking a measurement. This is often difficult because the operator’s hands are usually occupied with holding the probes during measurement, making it hard to press the hold button!
This feature is frequently seen on digital multimeters and is packaged separately from the thermocouple probe. This probe is used to determine an object’s temperature.
Clear Display With Big Digits
This can make taking readings easier, and the display can also be seen from a distance if necessary.
This allows the use of the digital multimeter in low-light conditions.
- Some less expensive digital multimeters have a “CAT II rating.” But be careful because some manufacturers don’t test these multimeters to see if they meet the CAT II rating and just put the label on them anyway.
- The probes should also be rated for CAT III use and have finger guards to protect the user from touching any bare metal.
- When looking at a digital multimeter’s accuracy, the voltage is the most important thing to check. For most people, ±0.5% accuracy on a 2000 count multimeter is good, even if you are an electronics professional. If your meter has a higher count, the accuracy should be correspondingly better.
- Resistance (Ω) is the second parameter you should look at, and it should be close to the accuracy of the DC voltage.
- Generally speaking, the current accuracy of ±1-1.5% is not good enough for working on electronics. This suggests that the digital multimeter is not reliable for this purpose.
The more counts a digital multimeter has, the better it is. However, this does not mean that the meter can be less accurate. This can be checked by using the basic formula below. According to the table below, a good multimeter should have at least 4000 counts (according to the table below), which gives it a DC voltage accuracy of ±0.25%.
True RMS and AC bandwidth
Good professional multimeters (usually labeled with ‘True RMS’) will measure the alternating current (AC) sine wave. This provides a more accurate measurement of AC current and AC voltage.
The bandwidth is measured in kHz for an analog voice signal since an AC sine wave is used. Because of this, the higher the frequency range, the better.
- Most top-quality digital multimeters have a maximum AC bandwidth of around 100 kHz.
- Some digital multimeters have a maximum AC bandwidth of 1 kHz – 0.5
However, AC bandwidth is less important for the regular digital multimeter.
Display Updating Speed
This is how often the display is updated when measuring something. The faster the update, the more closely representing what you are measuring. This is especially important if the thing you are measuring is changing quickly.
- Some multimeters have digital displays that quickly show information four times per second.
- Some less expensive digital multimeters will update their display about 2 times a second.
- Some expensive digital multimeters update the display 8 – 15 times a second.
Digital multimeters with a low-pass filter can be helpful when working on motor drives and other noisy circuits. The filter will eliminate the high-frequency noise generated within such circuits. However, for a regular everyday-use meter, this feature is not essential.
The digital multimeter should be durable and have features that protect it from damage.
If you intend to do additional current measurements with your digital multimeter, the burden voltage of the meter (or the voltage drop when a meter is connected in series with the circuit) should not exceed 1mV per mA.
Non-essential Features of Digital Multimeters for Electronics Work
Transistor hFE tester
This is a feature not usually used by people who work with electronics. It is not a common feature on high-end digital multimeters.
Frequency & Duty Cycle
Another feature not often used on digital multimeters is making frequency and duty cycle measurements. This is because oscilloscopes are better suited for doing this job. However, if the frequency feature on a digital multimeter, the higher the range, the better. This is especially true at kilohertz (kHz) to megahertz (MHz) frequencies.
Data-Logging and Graphing Digital Multimeters
These types of digital multimeters are more expensive than regular digital multimeters. They often have fewer features, but the price is lower. However, they use a lot of battery power, so they’re not good for everyday use.
Digital Multimeter Reviews
AstroAI DM6000AR (WH5000A) Multimeter
The AstroAI DM6000AR multimeter is a good choice for people who are into electronics hobbies or work. It has many features that more expensive multimeters have, including a 6000 count machine with great accuracy.
The DM6000AR multimeter has a sampling rate of two times per second. This is a good rate for a budget multimeter. The measurements are taken automatically, but the DM6000AR can also take measures manually if needed. Although the automatic process is not as quick as some high-end premium multimeters, it is fast enough for regular use.
The DM6000AR is useful for both electronic and electrical work. It can measure down to the millivolt range for DC voltage and a maximum of 1000V for DC voltage. The input terminals are rated Category III (CAT III) up to 600V.
The AstroAI multimeter measures different types of electric current. It can measure ohms, megohms, amps, and volts/resistance. It also has separate input terminals for amperage and voltage/resistance measurements. This makes it safer to use.
The DM6000AR multimeter includes high-quality ceramic fuses on the Amp and milliamp terminals. These fuses protect the machine from high currents that the multimeter can’t handle. In addition, these fuses are cleverly designed to be user-accessible through the battery access door without disassembling the whole machine. However, the only reservation someone might have with these fuses is that replacements can be tricky, especially when finding the correct physical size.
The AstroAI DM6000AR multimeter can measure various things, like transistor and diode values, capacitance down to the nanofarad range, and temperature over a wide range. The DM6000AR also has a ‘relative’ function that helps to eliminate resistance errors caused by probe leads. Additionally, the ‘Max/Min’ and ‘Hold’ buttons are useful for freezing measurements on screen when continuously observing them is not convenient.
The DM6000AR multimeter can be used to test for continuity. If the resistance is lower than 30Ω, the multimeter will noise. It is important to note that the multimeter must be configured explicitly for the buzzer to sound. Some new owners have been confused when their device does not noise during continuity testing. The multimeter can also measure frequency from the hundreds of kHz range to the tens of MHz range, making it perfect for square and sine waveform inputs.
The DM6000AR has a large clear display with big digits. Backlight that can be turned on at the press of a button. This is useful when working in poorly lit areas. The backlight only stays on for 15 seconds or so, which can sometimes be too short a period for taking a measurement. The primary rotary dial determines the type of measuring function. Also features ‘Off’ positions on both sides of the dial selector circle, making it simple to turn off the machine without causing undue wear and tear to the dial mechanism.
The AstroAI device is unique because it has a strap and two magnets on its back surface. This allows the multimeter to be attached to metal surfaces, like an electrical cabinet door or a raised car bonnet. This way, you can hold the probes while you work.
The back of the multimeter also has a kickstand. This can be used to prop the machine upon a surface. The only issue is that the kickstand is not very strong and can be hard to deploy. After 15 minutes of being inactive, the multimeter also turns off to save the battery. However, this feature can be disabled if necessary.
The DM6000AR digital multimeter has a few negatives. These include the lack of a case to carry it in and the poor quality of the leads that come with it. If you want to get the most out of this machine, you should buy a higher-quality replacement set of leads.
Another disadvantage is the operating instructions that come with the DM6000AR. While it is written in easy-to-understand English, the physical dimensions of the manual are too little. And the text inside is tiny, making it tough to read for anybody over the age of 60.
AstroAI is headquartered in the United States, but it is actually a Chinese company that makes all its products in China. The DM6000AR multimeter is a budget model with negative implications for quality control and long-term reliability. Still, the service from the company is usually very good. They are responsive, especially if the product develops a fault during the warranty period.
Overall, the AstroAI DM6000AR is a good multimeter. It is good for people who like electronics. They have all the things they need for their work and some extra features. If you want a multimeter to start your career in electronics, this is a good one to get. It doesn’t cost too much money either.

Factors Considered For Choosing The Best Multimeter Electronics Hobbyist
Digital multimeters are now more common because they are cheaper and more precise. Before you buy one, there are some things you need to consider. For example, lists of features can be a good starting point, but they aren’t good for comparisons. Which digital multimeter is the best for electronics among the top ten multimeter brands, and which isn’t? Choose the characteristics that matter the most to you.
When buying a multimeter for electronics, it is important to understand the most important features. By understanding which features can be sacrificed to save money, you can choose a multimeter that fits your needs.
Considerations for Best Multimeter Electronics
You must use this product correctly. Electricity can be dangerous if it isn’t dealt with properly. Even though we have followed a minimum safety standard, we don’t want any accidents.
A multimeter’s resolution is the smallest part of the scale it can measure. This means that it can measure very tiny changes in signal value.
Assume that a 10-volt digital multimeter has a resolution of 1 millivolt. In that situation, a change of one millivolt is visible. The accuracy of the digital multimeter’s measurements is often expressed as a tolerance given on a data sheet. Higher accuracy will help create more precision when measuring.
Auto-ranging is a useful function that assists the meter in measuring the most critical numbers. For example, suppose you measure 14.21V instead of .01421V because of the auto-ranging feature. In that case, you only need to select AC/DC mode. If you are looking for a good multimeter, it is important to find one with this feature.
The best multimeter for electronics has safety ratings that follow the guidelines from IEC61010. Safety ratings are important for engineers working with high levels of electricity.
It is very important to read any electrical test equipment instructions before using it. This will help you stay safe and use the equipment correctly. It is also good to buy the best multimeter electronics with good safety features.
When choosing a multimeter, it is important to think about the warranty. This helps safeguard your investment if something goes wrong with the multimeter.
This device costs a lot of money. If you buy it, you may not use it for a long time. Make sure that you know what the warranty covers. There is a five-year standard warranty with these devices most of the time. In some cases, the warranty can be even longer.
You should also research the company before you buy a product. Ensure that the customer service department is qualified and capable of helping you if something goes wrong with the product. Additionally, find out if you will have to pay shipping costs to send the product back to the company for repair. Sometimes it is more expensive to redeem a lower-end model warranty than just buying a new one, and the process can take longer.
When you are choosing an electronic tool, safety is always very important. Suppose you’re a newbie learning how to measure resistance levels. In that case, you should go with a low-cost multimeter where safety isn’t as crucial. A professional multimeter that measures DC or AC voltages will have to comply with safety features, such as CAT safety measures, so their priority is safety.
The greatest multimeters for electronics come in a variety of sizes. Multimeters exist in various sizes and designs, but the best are typically small and portable. However, they can’t get as good of a charge as the bigger multimeters, so they might not be the best option if you need to use them often. Some powerful multimeters come with jump starts, but they are also heavier, and if you keep them in your car, they will take up your entire trunk space.
Where Are Multimeters Used?
A multimeter is a common tool for repairing and installing batteries and other power supplies. It is often used in electronics. Some common applications where it is integral are repairing household wiring and other power supplies.
- Automotive repairing
- Repairing of any electrical and electronic device.
- Installation of electronics items.
- Electrons component validation
- Household electrical wiring and trouble shootings
What is a Multimeter?
A multimeter is a gadget that can detect and measure various electrical currents. You can use it to measure voltage, current (amperage), and other properties of electricity. It is handheld, so it is easy to move around. Multimeters come in two types: volt-ohm meters (VOM) and volt-ohm-milliampere meters (VOMM). VOMMs measure voltage, resistance, and current, while VOMs only measure voltage and resistance.
Multimeters come in different levels of readings. You can use the most simple type of multimeter to figure out what kind of wires are, how much electricity is going through them, and how much resistance they have.
- Measure voltage like a voltmeter.
- Measure current like An ammeter
- Measure resistance like An ohmmeter
How to Use a Multimeter?
Multimeters come in two types: analog and digital. In both types, the function and operation are similar. They have two probes, red and black, and three ports. The black probe connects to the standard port, while the red probe goes to the other ports.
These devices offer many different testing options, like measuring volts, amps, and ohms. They also have more advanced options and specialized features. This makes them good for people with specific requirements.
To get a reading, make sure the probe ends of each component make contact with the meter’s terminals. Using a multimeter is safe as long as the current or voltage being measured does not exceed the maximum rating of the meter.
When the tester is turned on, touching the metal ends will shock. Don’t touch the metal when it’s plugged in, or you can get a shock.
Frequently Asked Questions About Best Multimeter for Electronics
Fluke’s 115 Field Technician’s Digital Multimeter and 117 Electrician’s Multimeter are excellent tools for working with electronics. They are both updated and have a lot of features.
Suppose you are doing electrical work that involves mains voltage. In that case, it is a good idea to use a true RMS meter that is rated for safety. Most electronics work does not require this, but if you need to look more deeply into the issue, you should save money and get an oscilloscope instead. An oscilloscope will tell you much more than a regular meter.
The HTC Instrument DM-97 3 3/4 Digital Multimeter 4000 Counts, Capacitance, Frequency, Temperature is a more affordable and reliable version of a digital multimeter. It has a frequency of 0.1Hz ~ 30MHz and can measure DC voltage up to 1000 V and AC voltage up to 750 V.
The INNOVA 3320 is a low-cost, digital multimeter mainly aimed at DIY hobbyists and auto industry technicians. It has many more expensive multimeters features, but it may not be accurate. The battery test feature is also useful.
It is a classic case of “you get what you pay for.” If you need occasional, reasonably accurate readings, you might consider a less expensive meter. If you need frequent and highly accurate readings, there is nothing better than a Fluke.
The Fluke 117 Electrician’s Multimeter has a 10 amp current range for making AC or DC current measurements. The maximum resolution is 1 milliamp.
Suppose you need to determine the voltage or current of an alternating current signal that is not a pure sine wave. In that case, you need a meter that can accurately measure these types of signals. This is called a “true RMS” meter.
A true-RMS meter can precisely measure both perfect sinusoidal and imperfect non-sinusoidal waves. “RMS” stands for root-mean-square, which is a calculation used to find the equivalent DC value of an AC waveform.
Many multimeter brands are available, but Fluke is the most popular and trusted brand. Brymen and Amprobe are two other good brands that make quality multimeters.
A meter that can measure “real RMS” is required to measure the voltage or current of AC signals that aren’t pure sine waves. This is important when measuring the output of adjustable speed motor controls or adjustable heating controls.
The number of digits should be around 2000 to 4000 or maybe 6000. That will make the price tag higher, though. You need to measure AC and DC voltage, current, and resistance. The input impedance should be around 10MOhm. Continuity testing is a must.
