When it comes to measuring electrical values, two terms often come up – avometer and multimeter. But which one is the proper word to use? The answer is both.
An avometer is a type of multimeter that was first introduced by the British Post Office in the early 1920s. It is a device used to measure electrical values such as voltage, current, and resistance. A multimeter, on the other hand, is a more modern version of the avometer that can measure a wider range of electrical values and often includes additional features such as capacitance and frequency measurement.
In this article, we will explore the differences between avometers and multimeters, their history, and the advantages and disadvantages of each.
Define Avometer
An avometer is an electrical measuring instrument that was developed in the early 20th century. It is a type of analog multimeter that measures voltage, current, and resistance. The name “avometer” is derived from the words “ampere” and “voltmeter,” which are the two primary functions of the instrument.
Define Multimeter
A multimeter is a versatile electrical measuring instrument that is widely used by electricians, technicians, and hobbyists. It is a digital or analog device that can measure voltage, current, resistance, capacitance, frequency, and other electrical parameters. Multimeters come in various types and models, ranging from basic models for home use to advanced models for professional use.
How To Properly Use The Words In A Sentence

Common Mistakes To Avoid
When it comes to electrical testing, many people use the terms “avometer” and “multimeter” interchangeably. However, these are two different tools with distinct functions. Here are some common mistakes people make when using avometer and multimeter interchangeably, and why they are incorrect.
Using The Wrong Tool
One of the most common mistakes people make is using the wrong tool for the job. An avometer, also known as an AVO meter, is an analog meter that measures current, voltage, and resistance. It is best used for testing DC circuits and is not suitable for testing AC circuits. On the other hand, a multimeter is a digital meter that can measure AC and DC voltage, current, and resistance. It is a versatile tool that can be used for a wide range of electrical testing tasks.
If you use an avometer to test an AC circuit, you may get inaccurate readings or even damage the tool. Similarly, if you use a multimeter to test a DC circuit, you may not get accurate readings. It is essential to use the right tool for the job to ensure accurate results and prevent damage to the tool.
Incorrect Range Selection
Another common mistake people make is selecting the wrong range on their meter. Both avometers and multimeters have different ranges for measuring voltage, current, and resistance. If you select the wrong range, you may get inaccurate readings or even damage the tool.
For example, if you are measuring a voltage of 12 volts and select the 1000-volt range on your meter, you may get an inaccurate reading. Similarly, if you are measuring a current of 1 ampere and select the 10-ampere range on your meter, you may damage the tool. It is essential to select the correct range for the measurement you are taking to ensure accurate results and prevent damage to the tool.
Not Zeroing The Meter
Another mistake people make is not zeroing their meter before taking a measurement. This is especially important when measuring resistance. If you do not zero your meter, you may get inaccurate readings.
To zero your meter, you need to short the test leads together and adjust the meter to read zero. This ensures that any resistance in the test leads or connections is accounted for, and you get an accurate reading.
Tips To Avoid These Mistakes
To avoid these common mistakes, here are some tips:
- Read the manual for your meter and understand its capabilities and limitations.
- Select the correct tool for the job.
- Select the correct range for the measurement you are taking.
- Zero your meter before taking a measurement, especially when measuring resistance.
By following these tips, you can avoid common mistakes when using avometers and multimeters interchangeably and ensure accurate results.
Context Matters
When it comes to choosing between an avometer and a multimeter, the context in which they are used plays a crucial role. While both devices serve the same purpose of measuring electrical values, the choice between them can vary depending on the specific situation.
Examples Of Different Contexts And How The Choice Between Avometer And Multimeter Might Change:
- Industrial settings: In industrial settings, where the electrical systems are complex and the voltage levels are high, avometers are preferred over multimeters. This is because avometers are designed to handle high voltage levels and can provide accurate readings even in noisy environments.
- Home use: For basic electrical measurements around the home, a multimeter is often the better choice. They are more affordable and easier to use than avometers, making them a popular choice for hobbyists and DIY enthusiasts.
- Automotive applications: When working on cars and other vehicles, a multimeter is often the preferred choice. This is because they are more versatile than avometers and can measure a wider range of electrical values, including resistance, current, and voltage.
Ultimately, the choice between an avometer and a multimeter depends on the specific context in which they are being used. By understanding the differences between these two devices and considering the specific needs of the situation, it is possible to make an informed decision and choose the right tool for the job.
Exceptions To The Rules
While avometers and multimeters are versatile tools that can be used to measure a wide range of electrical parameters, there are some exceptions to the rules that apply to their use. Here are some cases where the rules might not apply:
Exception 1: High-frequency Measurements
In general, both avometers and multimeters are designed for measuring low-frequency electrical signals. Therefore, they might not be suitable for high-frequency measurements. In such cases, specialized instruments like oscilloscopes or spectrum analyzers might be more appropriate.
For example, if you need to measure the frequency of a radio wave, an avometer or multimeter might not be able to provide accurate measurements due to their limited frequency response. In such cases, you might need to use a spectrum analyzer or a frequency counter to obtain accurate readings.
Exception 2: High-voltage Measurements
While both avometers and multimeters are capable of measuring high voltages, there are some cases where their use might not be recommended. For example, if you need to measure voltages above 1000 volts, you might need to use specialized high-voltage probes or meters that are designed for such applications.
Similarly, if you need to measure voltages in high-impedance circuits, you might need to use specialized instruments like a high-impedance voltmeter or a megohmmeter. This is because avometers and multimeters might load the circuit and affect the accuracy of the measurements.
Exception 3: Temperature Measurements
While some avometers and multimeters come with built-in temperature sensors, their accuracy might not be sufficient for some applications. For example, if you need to measure temperatures in a high-temperature environment, you might need to use specialized thermocouples or infrared thermometers that are designed for such applications.
Similarly, if you need to measure temperatures in a low-temperature environment, you might need to use specialized thermistors or cryogenic thermometers that are designed for such applications.
Exception 4: Specialized Applications
Finally, there are some specialized applications where avometers and multimeters might not be suitable. For example, if you need to measure the resistance of a battery or a capacitor, you might need to use specialized instruments like a battery tester or a capacitance meter.
Similarly, if you need to measure the current flowing through a high-power circuit, you might need to use specialized current probes or shunts that are designed for such applications.
| Exception | Recommended Instrument |
