Analog Multimeter vs. Digital Multimeter

What's the Difference?

Analog multimeters and digital multimeters are both commonly used tools for measuring electrical quantities, but they differ in their display and measurement capabilities. Analog multimeters have a needle that moves across a scale to indicate the measured value, while digital multimeters have a digital display that shows the exact numerical value. Analog multimeters are generally considered to be more suitable for measuring rapidly changing values or fluctuations, as the needle provides a visual representation of the changes. On the other hand, digital multimeters offer higher accuracy and precision, as they can display measurements with decimal points and have a wider range of measurement options. Additionally, digital multimeters often come with additional features such as auto-ranging, data logging, and connectivity options, making them more versatile and user-friendly.

Further Detail


When it comes to measuring electrical quantities, multimeters are indispensable tools for both professionals and hobbyists. Multimeters are versatile devices that can measure voltage, current, and resistance, among other electrical parameters. There are two main types of multimeters available in the market: analog multimeters and digital multimeters. While both serve the same purpose, they differ in terms of their design, functionality, and ease of use. In this article, we will explore the attributes of analog and digital multimeters, highlighting their strengths and weaknesses.

Analog Multimeters

Analog multimeters have been around for decades and were the go-to choice for electrical measurements before the advent of digital technology. These multimeters utilize a mechanical movement, such as a needle, to display the measured values on a scale. One of the key advantages of analog multimeters is their ability to show changes in readings more intuitively. The needle movement provides a visual representation of the measured quantity, allowing users to quickly observe fluctuations or trends. Additionally, analog multimeters are generally more affordable compared to their digital counterparts, making them a popular choice for budget-conscious individuals.

Another advantage of analog multimeters is their ability to measure rapidly changing signals or transients. The analog nature of these devices allows them to respond quickly to fluctuations in electrical signals, making them suitable for troubleshooting dynamic circuits. Furthermore, analog multimeters do not require batteries or external power sources to operate, as they rely solely on the electrical energy being measured. This can be advantageous in situations where power sources are limited or unavailable.

However, analog multimeters also have their limitations. One major drawback is their lower accuracy compared to digital multimeters. Analog multimeters typically have a limited number of scales, making it challenging to read measurements with high precision. Additionally, the analog display can be prone to parallax errors, where the angle of view affects the reading accuracy. This can lead to inaccuracies and misinterpretation of measurements, especially for inexperienced users.

Furthermore, analog multimeters are generally bulkier and heavier than their digital counterparts. The mechanical components required for the needle movement and scale can add to the overall size and weight of the device. This can make analog multimeters less portable and less convenient to carry around, especially for professionals who need to work in various locations.

Digital Multimeters

Digital multimeters, on the other hand, have gained popularity in recent years due to advancements in digital technology. These multimeters utilize digital displays, such as LCD screens, to present the measured values in numerical form. One of the key advantages of digital multimeters is their high accuracy and precision. The digital display allows for easy reading of measurements with decimal places, enabling users to obtain more precise results. Additionally, digital multimeters often offer a wide range of measurement functions and modes, making them versatile tools for various applications.

Another significant advantage of digital multimeters is their enhanced ease of use. The numerical display eliminates the need for interpreting needle movements or scales, reducing the chances of reading errors. Digital multimeters also often include additional features such as auto-ranging, which automatically selects the appropriate measurement range, and hold functions, which freeze the displayed value for easy recording. These features make digital multimeters more user-friendly, especially for beginners or those who are less familiar with analog devices.

Furthermore, digital multimeters are generally more compact and lightweight compared to analog multimeters. The absence of mechanical components allows for a smaller form factor, making digital multimeters highly portable and convenient for on-the-go use. Additionally, digital multimeters often come with built-in batteries or rechargeable power sources, ensuring continuous operation without relying on external power supplies.

However, digital multimeters also have their limitations. One drawback is their limited ability to measure rapidly changing signals accurately. Digital multimeters may struggle to capture fast transients due to their sampling rate and response time. This can be a disadvantage when working with circuits that involve high-frequency signals or quick fluctuations. Additionally, digital multimeters are generally more expensive compared to analog multimeters, especially for models with advanced features and higher accuracy.


In conclusion, both analog and digital multimeters have their own set of advantages and disadvantages. Analog multimeters excel in providing a visual representation of measurements and are often more affordable. They are suitable for troubleshooting dynamic circuits and do not rely on external power sources. However, they lack the precision and ease of use offered by digital multimeters. Digital multimeters, on the other hand, provide high accuracy, easy reading, and a wide range of features. They are compact, portable, and suitable for various applications. However, they may struggle with rapidly changing signals and tend to be more expensive.

Ultimately, the choice between an analog multimeter and a digital multimeter depends on the specific requirements and preferences of the user. Professionals who prioritize accuracy and ease of use may opt for digital multimeters, while hobbyists or those on a budget may find analog multimeters more suitable. Regardless of the choice, both types of multimeters remain essential tools for electrical measurements, ensuring safe and efficient troubleshooting, maintenance, and experimentation in the world of electronics.
