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.

Why are electrical transformers measured in KVA and motors in KW

By
Why are electrical transformers measured in KVA and motors in KW   Why are electrical transformers measured in KVA and motors in KW Welcome to the Electron Tips website. In this topic, we will learn about the reason for measuring electrical transformers in the unit KVA (kilovolt-ampere) and electric motors in the unit of kilowatt (KW).   Why electric motors are measured in KW:  An electric motor is an electrical device that consumes effective electrical power, which is why it is expressed in units of kilowatts or horsepower because it expresses the amount of electrical energy that the motor has benefited from, and it means the actual power used for mechanical purposes and expresses the actual performance of the electric motor (effective power), because  Inefficient power will do nothing for the electric motor.   The reason for measuring electrical transformers in KVA:  Electrical transformers' primary role is to convert electrical voltages, as they do not ...

What is a perfect ground resistance value   What is a good ground resistance value Grounding is considered one of the most important systems that must be present in all electrical installations, whether in homes, buildings, or even power transmission lines. Grounding is essential for protecting people and electrical equipment from electric current leakage.  Previously, we provided a comprehensive guide on how to establish a grounding system from scratch and the key components you would need. You can view the topic [ here ]. In this article, we will explore the optimal value for good grounding resistance and how you can measure it using a Megger device. Optimal Grounding Resistance Value: Before installing a grounding system in the soil, it is essential to measure the earth resistance value using a Megger Device, especially if sensitive devices and equipment will be installed in the area. The ideal earth resistance value is zero, though achieving this value is practically impos...

Is lightning direct current or alternating current

By
Is lightning direct current or alternating current  Is lightning direct current or alternating current Many people ask about the type of electricity found in lightning, and in this small article we will explain to you whether lightning is a continuous or alternating electrical current. First, let us get to know the definition of the phenomenon of lightning and how it occurs.   Definition of lightning:  Lightning is a massive electrical discharge, meaning it contains very high electrical energy, ranging from 1 to 10 million joules. The temperature of lightning may reach 30,000 degrees Celsius, and this discharge may occur between the ground and the cloud or between two clouds together. Related articles: Can the capacitor charge the battery   The answer to the question: What is the electric current in lightning?  The electric current in lightning is an alternating electric current because it changes direction quickly and repeatedly in a short time over a short per...
