An avometer or multimeter is a measuring instrument needed when repairing or even creating an electrical circuit. With the help of this tool, you can easily detect the electrical condition of electronic items. 

To get to know it better, please refer to the definition & parts of the avometer below. 

Getting to Know the Multimeter Better

The definition of an avometer is a reliable measuring tool for measuring electrical components, whether it is electric current (ampere), electrical resistance (Ohm), or electric voltage (Voltage). From its function, it can be concluded that this measuring instrument is a combination of 3 different measuring tools. 

This trusted measuring tool for electrical technicians is divided into two types consisting of analog multimeters and digital multimeters. 

An analog multimeter is a measuring tool equipped with a needle and a range of numerical results as its hallmark. In other words, the user performs calculations manually and requires precision when determining the voltage.

Meanwhile, the digital multimeter feels easier to use and produces more accurate voltage values. It is said to be more practical because users do not need to set the measuring tool first, and the results will be displayed on its digital screen. 

This sophisticated tool not only measures resistance, voltage, or electric current but also measures the Hfe of transistors.

Parts of the Avometer / Multimeter 

Understanding the definition & parts of the avometer is important to do before trying to operate it. Besides reducing the risk of damage due to misuse, this also helps you read the voltage value on a component accurately.

If observed closely, you will realize that this measuring instrument consists of several parts. To get to know it better, let’s break down each part and understand its function. 

The first part to know is the maximum scale (scale), where this part shows the highest value limit on a panel. 

If you want to measure resistance, the maximum limit is read from right to left, while the maximum limit for measuring current is the opposite. 

The second part is the pointer needle, which serves as an indicator of the measurement scale. Each part has a different function, therefore it is important to understand the definition & parts of the avometer. 

The zero correction needle is the part that will zero the needle to the left position when measuring current and voltage. 

Ohm Adjust (ohm scale adjuster) is the opposite of zero correction, as this tool functions to zero the needle to the right position when measuring resistance.

Range selector is the choice of range, resistance, or voltage to be measured. Meanwhile, the terminals consist of a red cable (+) and a black cable (-), which are terminals that measure AC Volt, DC Volt, Ohm, and DC mA. 

Having various functions, this is the importance of understanding the definition & parts of the avometer before using the tool. 

For laypeople, reading an avometer for the first time can be quite a difficult task. Because this measuring tool is filled with numbers and consists of only two cables as its measuring components. 

However, this task will be easier after knowing each part of the avometer.
