Which multimeter should I buy? It is not a question of beginners but also professionals. When looking for a multimeter, there are a few factors you should consider. The first is what type of measurements you need the multimeter to make. There are digital and analog multimeters.
When buying a multimeter in 2024, prioritize features like accuracy, versatility, durability, and ease of use. Consider factors such as measurement range, safety ratings, display clarity, and additional functions.
Digital multimeters are more common and can measure voltage, current, and resistance. They also have a built-in thermometer. Analog multimeters are less common and can measure voltage, current, and resistance. But if you're curious about what to look for in a multimeter then there are multiple factors involved.
Analog multimeter and Digital multimeter what to choose?
When looking for a multimeter I always prefer a digital multimeter over an analog multimeter due to the following reasons.
Things to look for in a multimeter-A complete multimeter buying guide
So, what to look for in a multimeter? When you are looking for a multimeter, there are multiple factors that you should consider to grab the best multimeter.
1. Display
The display is one of the most important factors to look for in a multimeter. The display should be large, have a backlight, and be easy to read, especially in low light. In DMM the display resolution is very important never buy a multimeter with a display count under 2000.
2. Accuracy
The accuracy of a multimeter is all about how accurate readings you can get with it. A reliable multimeter had an ac/dc voltage accuracy of 1%. If you're going to be taking measurements that require a higher degree of precision, then consider getting a multimeter with True RMS reading and low impedance mode.
3. Auto-ranging
If you're a beginner then Multimeter with a manual range can cause many issues. Because you have to be conscious all the time to set the right range. So it's better to get a multimeter with auto-range instead of manual ranging. When looking for a multimeter, you should get one that has an auto-ranging function to save time. Auto-ranging is the ability of a multimeter to automatically select the range that is most appropriate for the measurement being taken.
4. AC/DC Voltage range
The voltage range is the maximum voltage that the multimeter can measure. If you're going to be measuring high voltages, you'll need a multimeter that can measure up to 1000 volts.
5. AC/DC Current range
The current range is the maximum amount of amperage the multimeter can measure. A multimeter with a range of 10 amps is ideal for measuring electronics circuits because most circuits use up to 10 amps. To measure current above 10amps you should use clamp meters. I have also made a list of the best camp meters to measure electrical current in all ac dc circuits.
6. Safety Rating
The safety rating is the maximum voltage that the multimeter can withstand without being damaged. Most multimeters have a cat-iii safety rating of 600 volts.
7. Digital Multimeters Input Protection
The internal protection of a multimeter is the amount of current that the multimeter can withstand without being damaged. Most multimeters have internal protection with ceramic fuses at the input side.
8. External Protection
The external protection of a multimeter is how well it's shielded from physical damage. A multimeter with good external protection will have a hard case and be tested to IEC 61010-2-031 safety standards.
9. Temperature Measurement
Most digital multimeters have this feature but if you need a multimeter with extreme temperature measurement, then consider getting a multimeter with a thermocouple input. Moreover, for HVAC technicians temperature probe is a must t get more accurate readings. You can also read reviews of the best multimeters for HVC technicians on my blog.
What Multimeter Should I Buy?
Every job has different measuring requirements. So you always need a different multimeter. There are also multi-purpose multimeters available in the market. So, here I will some best multimeters for electrical and electronics concerns.

Conclusion
When choosing a multimeter, you should consider the features that are most important to you. So, what to look for in a multimeter? If you need a meter for general use, then an auto-ranging meter is a good choice. If you need to measure high voltages or currents, then you should look for a meter with a high voltage or current range. Also, if you need to use the meter in a tight space, then consider buying one with a detachable display.
However, the most important thing to keep in mind, however, is a multimeter's accuracy. Be sure that whatever meter you buy has a voltage or current range that is at least slightly more than the voltage you need to measure. Hopefully, you have made your mind so grab the one which suits you the most and let us know about your experience.

Frequently asked questions-FAQs
Why measuring voltage with a digital multimeter is better than an analog multimeter?
The answer is simple, digital multimeters are more accurate than analog multimeters. This is because the readings on an analog multimeter are based on a needle and if the needle is not calibrated right or even defective then you will get a wrong reading. On the other hand, digital multimeters have a digital reading and are hence more accurate.
What is the difference between True RMS and non-True RMS multimeters?
Multimeters can be classified as True RMS or non-True RMS depending on the way they measure voltage and current. Non-True RMS multimeters work on a simple average of the AC signal. This is why they display "half" of the True RMS values when measuring sine waveforms. Moreover, true RMS multimeters, on the other hand, take the square root of the average value of the AC signal. This is why they display the "true" RMS value for all waveforms.
Measuring ac and dc values with all fluke digital models possible?
Almost all Fluke digital multimeters are capable of measuring both ac and dc values. The only exception is Fluke 101, which is a non-contact tester.
