What is an advantage of using digital multimeters over analog ones?

Digital multimeters are favored for their ability to provide more accurate and easy-to-read measurements compared to analog multimeters. The accuracy of digital multimeters arises from their use of modern electronics to convert analog signals into digital numbers, thereby minimizing errors associated with parallax and the subjective interpretation of needle positions on an analog scale. Additionally, the digital display eliminates uncertainty in reading values since the numbers are presented clearly, while analog meters can sometimes lead to misreading due to the moving needle and scale markings. This clarity and precision make digital multimeters particularly useful in various applications where exact readings are crucial, such as in electronics troubleshooting, circuit testing, and other technical fields.

In contrast to this choice, other aspects like cost, power requirements, and size may not be universally advantageous; for instance, while some digital models can be more affordable, many high-end digital multimeters are often more expensive than their analog counterparts. Similarly, many digital multimeters do require a power source, either through batteries or external power, which can be considered an inconvenience in certain situations. The physical size can vary greatly depending on the specific models being compared, with neither necessarily being universally lighter or smaller than the other.
