What is a Multimeter | How to use Multimeter device 

The multimeter has a very important role in the field of electronics and electricity, as it is considered the basic tool for measuring and testing all electronic components and elements. In this educational article, we will explain to you how to use the multimeter, so if you are a beginner in the field of electronics, this article is suitable for you to learn the basics of Multimeter in measure electronics components.

Definition of a Multimeter :

Multimeter is generally a tool that is more used to measure electrical and electronic systems, as it can measure electrical resistors, diode, voltage, electric current, and all electrical components depending on the type of device used because there are measuring devices sophisticated and with many advantages.

Explanation of the digital multimeter:

 The digital multimeter has several features, This is an explanation of the most important features of the digital multimeter.

 Measure electrical resistance.

 Measure electrical voltage.

 Measure the electric current.

 GND negative port.

 Voltage measuring outlet.

 Electrical outlet.

 For example, we want to measure electrical voltage. We place the negative “black” probe in an outlet that has the symbol com, which means the negative terminal of the Multimeter and the positive “red” probe with the symbol V, which means voltage, which is the unit for measuring electrical voltage. The same goes for measuring electrical resistances, where we put it on the symbol for ohms, and for electric current we put it on the symbol A. As for measuring some other electronic components, especially semiconductors, there are different methods that we will learn about in another article.

An important note :

to measure the electric current, we put the Multimeter in succession, but to measure the voltage, we put the Multimeter device in parallel, the load we want to measure the intensity of its electric current.

A reminder when using an avometer to measure anything, the pointer should be placed on a greater or close value to the thing we want to measure to avoid damage to the avometer. On AC, the indicator should be placed at 300 volts or more, because the voltage in the homes does not exceed 220 volts, depending on the system of the country in which you live.

Types of measuring and testing devices :

There are many types of measuring devices, starting with the old traditional devices that depend on the standard and the needle index, but nowadays there are advanced digital devices that show you value on a screen without the need to calculate anything, and these are some of the most famous measuring devices: 

Digital Multimeter :

This device has many advantages and advantages, as it can be measured by various physical ingredients such as electrical resistance, voltage and electric current only with one device.
