What is a multimeter and how to use it?
Multimeter is also known as Volt-Ohm meter and this device is used to measure voltage current and resistance. You will find two types of multimeters: analog and digital multimeters.
This device is very beneficial for measuring current, voltage and resistance of any component in any circuit. And with the help of this small device, we can detect voltage, current and resistance in any circuit anywhere.
If you want to make a circuit related to electronics, then you should know how to use a multimeter, only then you can find out the value of any component of a circuit. Analog multimeter has 1 moving pointer from which the reading is known. Let’s go.
But it could not tell the value of any component or voltage current exactly fixed, that is why its place has now been taken by digital multimeter, inside which you will see a display and it tells you exactly the fix value.
Because inside it you can also see the value of voltage, current or resistance in points, so that you can know the current, voltage and resistance of any circuit accurately.
So if you also want to know about multimeter theory in hindi, analog multimeter in hindi, multimeter kaise chalaye, multimeter kaise use kare, multimeter chalana sikhe multimeter, then in this post we are going to give you complete information about multimeter.

Invention of Multimeter
In 1820, a current-detecting device called galvanometer was made. In this device, resistance and voltage were measured through Wheatstone bridge. But the size of this device was large and it was a very slow working device. Due to which the value of voltage and resistance was not known properly.
The multimeter was invented as a radio receiver in the 1920s. The credit for making the multimeter goes to British Post Office engineer Donald Macadie. The meter invented by Macadie could measure voltage, current and resistance and was named Avometer.
How To Use Digital Multimeter In Hindi
As we told that digital multimeter has started being used in place of analog multimeter, that is why we will give you information about digital multimeter, how you can use it, how you can detect voltage current resistance and nowadays such Multimeters have also come so that you can find out the value of the transistor.
So as you can see in the photo above, we have shown all the points separately such that you will understand this multimeter more easily. Multimeter is used for testing and before testing you should keep some things in mind. It is very important.
If you want to measure any circuit or resistance with a multimeter, then first select its high range in the multimeter. For example, if you want to measure the electricity supply coming to your house. So you have to set the multimeter to 750v AC. And only after that you can measure the supply coming into your house.
display
You will see all the values on the display which you will check with the help of multimeter.
DC Voltage
To measure DC voltage, you have to set the selector key point of the multimeter in this section. With the help of this multimeter, you can measure DC supply from 200m to 1000 volts. But before measuring DC supply, you should have an idea of the value of the components. For example, if you want to kill the supply of a 9v battery, then you will have to select the range of at least 20v in the multimeter. If you select too big a range then you will not know the exact voltage of the battery and if you reduce it completely then there may be a fault in your multimeter.
While measuring DC voltage or AC voltage, you have to keep in mind that the probe installed in the multimeter should be set on the two terminals at the bottom of the multimeter as shown in the photo above.
While connecting a multi meter with a DC supply, you have to connect the positive probe of the multimeter to the positive terminal of the DC supply and the negative probe to the negative terminal of the DC supply. You can measure the voltage of that DC supply only by connecting it to the terminal.
AC Voltage
Like DC voltage, you get the method of measuring AC voltage in a multimeter, but in this you will get only two ranges, 200 and 750v. So if you want to measure the supply coming to your house then you will have to select 750v.
Only then can you measure the supply coming into your house. Like DC supply, to measure such supply, you do not need to see any kind of terminal, you can connect any probe to any terminal.
amperes
To find out the amperes of any circuit, you have to connect the multimeter in series with that circuit. But keep one thing in mind that this multimeter can only measure amperes of DC current. Use it in DC supply and use it in DC circuit.
In the above photo you can see how we have connected a DC motor in series with a multimeter. And which probe of the multimeter have we connected to the battery? So by looking at the photo you must have understood how to use a multimeter to measure the amperes of DC supply.
Continuity
We also use multimeter to check the continuity of any circuit. If you want to find out whether any wire has been cut in any circuit. For this you set the multimeter above continuity. And just like measuring voltage, you can check the continuity of the wire by placing probes on both ends of the wire.
By Continuity you can get any diode You can also check whether it works or not. For this you have to connect the positive terminal of the multimeter to the positive terminal of the diode and connect the negative terminal of the multimeter to the negative terminal of the diode. If your LED starts blinking then it means the LED is absolutely fine.
Resistor
any multimeter register or resistor It is very easy to find out the value, for this you have been given a range there. Just like you measure voltage. Similarly the register has to be measured. For this, first of all you have to select the register range of the multimeter and connect the probes of the multimeter at both ends of the register. And you will start seeing the value of the register on the multimeter.
multimeter price
Earlier multimeters used to be very expensive but now multimeters have become much cheaper than before, you can buy them online from ₹ 300 to ₹ 20000. The price of a multimeter depends on its function and its range. If you buy a multimeter of a good company, you will have to pay Rs 500 to 1000 for it. And if you want to buy a simple multimeter then it will cost you ₹ 200 to ₹ 500. Below you are given the link of some multimeters which you can buy online.
