Key Differences
An avometer, historically known as an AVO meter, is a type of multimeter that was specifically branded and widely used in the past. It derives its name from its capability to measure amperes, volts, and ohms. These meters were known for their robustness and accuracy, making them popular among professionals. In contrast, a multimeter is a more generic term for devices that measure electrical properties such as voltage, current (amperes), resistance (ohms), and sometimes additional parameters like capacitance and frequency.
While an avometer is traditionally analog and uses a moving coil meter to display measurements, modern multimeters can be either analog or digital, with digital versions providing more precise readouts and the ability to measure additional electrical characteristics. This makes multimeters versatile for a range of applications from simple DIY projects to complex industrial electrical inspections.
In terms of functionality, an avometer was mainly limited to measuring the basic electrical units: amperes, volts, and ohms. However, modern multimeters can perform a variety of functions and tests including continuity tests, diode tests, and temperature measurements, thanks to advanced integrated circuits and digital displays.
The design and user interface of an avometer often reflect its era, with a more rugged and less ergonomic build, suitable for the technology and user expectations of its time. Multimeters today are designed with user-friendly interfaces, digital displays, and features that accommodate the needs of contemporary users, including portability and ease of use.
Although avometers are less commonly used today, replaced largely by more modern digital multimeters, they are still valued by some for their durability and historical significance in the field of electronics and electrical engineering. On the other hand, multimeters continue to evolve, incorporating new technologies and features that extend their applicability and functionality in various electrical and electronic work.

Common Curiosities
What makes an avometer different from other multimeters?
An avometer is a specific brand known for its robustness and traditional analog design, focusing on basic measurements.
Why might someone prefer an analog avometer over a digital multimeter?
Some prefer analog avometers for their visual response and durability, especially in environments where digital devices might fail.
What is the typical cost difference between an avometer and a digital multimeter?
Digital multimeters can range widely in price, often based on their additional features. Basic models may be comparably priced to traditional avometers, but more advanced units can be significantly more expensive.
Are avometers still manufactured today?
While avometers as a specific brand are not commonly manufactured today, similar analog multimeters are still produced by various companies.
What should I consider when choosing between an avometer and a multimeter?
Consider the specific measurements you need, the environment in which the device will be used, and whether advanced functions like digital readouts and additional testing features are required.
Can I use a modern multimeter for the same tasks as an avometer?
Yes, modern multimeters can perform all the functions of an avometer and more, with greater precision and additional features.
Can multimeters measure anything that avometers cannot?
Yes, multimeters often include capabilities to measure capacitance, frequency, and sometimes temperature, which are not typically available on avometers.
What are the most common failures in avometers and how do they compare to multimeters?
Common failures in avometers include wear and tear of mechanical components and fading of the meter display. Multimeters might face issues like battery drain, LCD failures, or circuitry problems, especially in cheaper models.
What are the maintenance requirements for avometers compared to multimeters?
Avometers typically require periodic calibration and may need careful handling due to their analog nature. Digital multimeters also require calibration but are usually more robust against environmental factors.
How do the safety features of avometers and multimeters compare?
Modern multimeters usually have superior safety features, including fuse protection, overload protection, and features like auto power-off, which might not be present in older avometer models.
How does the accuracy of avometers compare to modern digital multimeters?
Generally, modern digital multimeters offer higher accuracy and more reliable measurements compared to traditional analog avometers.
Is there a difference in the learning curve between using an avometer and a multimeter?
Digital multimeters might have a steeper learning curve due to their additional functions and settings, whereas avometers are generally straightforward due to their focus on basic measurements.
How does the display type affect the usability of avometers vs. multimeters?
The analog display of avometers may be preferred for dynamic measurements where changes can be seen continuously, while digital displays provide precise numerical values which are easier to read and record.
Can either device be used for all electrical measurements in household DIY projects?
For most household DIY projects, a multimeter is sufficient and often preferred due to its versatility and ease of use.
