Hello and welcome to this annual us on the I will talk about digital multimeter.
This is a quick introduction to this device the one that I will be showing you is unity as you can see.
OK.
Let me show you a few things.
Now this device is basically used for showing on this LCD trailing digital readings for VoLTE on Amber
and other stuff that I will talk about now.
So let's say a quick introduction to the basic components here.
Now if you looked at the bottom here you find there is a comb which is common.
Usually we connect the black wire to this opening or this whole.
And here we have like three openings each one with the type of the thing that it's used for measuring.
So.
So this one is used for image Max.
So Max if you placed any device that will consume more than 10.
The fuse will be blown.
So this one is used to measure current and Millie arms and its use or use also for measuring the temperature
and sleaziness.
This opening is used for measuring bolt on the diode and the Hertz as you can see each of these is used
for a certain thing.
You can't use it for any other thing.
Now this move up here as you can see we have this LCD display.
It's used for supplying the results.
And if you take a good look at it you will find that it has a lot of things.
Now we have the ball button here.
If you clicked on that put on the display will turn on.
We have the whole button here.
If you click the ball button and took a reading then press the whole button the rating will remain on
this.
I'll see visibly at one move as you can see it's taking hold.
OK.
Now this is a quick introduction here in the back.
We have like something that can help keeping this up if you want to use it to take readings.
Now let's take a look at this dial as you can see.
You can move a way to choose different things.
Now if we turned on the ball and let's start from the bottom on start with umpires as you can see here
we can miss out 20 million beer two hundred million beer up to 10 bear AC as you can see a with the
sign wave shape means.
This will be used for a series of things.
And if we we moved here from 10 200 Millie and 20 Emily and bear they see this constant line means DC
for these three will be used for these readings.
And if we want to measure of the House we will move this.
It will measure up to 20 kilohertz if we want to measure the Cubs.
We can measure from two nano micro or none of allowed to 200 micro followed.
As you can see you can change everything from here.
If you want to measure that in the child you can choose this one.
If you want to measure of other readings such as diode or connectivity you can choose from here.
Let's move on.
This is the only reading.
Let me just as it what you can see here.
We have
starting from 200 ohm to scale 20 kilo 200 killed two mega one 20 Mega and 200 mega all.
So all of these can be used for reading.
That is a stance next.
We have these readings for Volt as you can see there's a constant line.
So volt DC starting from from 290 to twenty two hundred and 1000 volt.
Here is the same.
We have Volt with the sine wave shape which means AC evolved to twenty two hundred and 750 volt AC.
So you just need to move the dial to this point so that you can take the readings and volts and it will
adjust itself.
The LCD screen.
Now one thing that you need to know before moving on is that when you choose the reading from here if
you want to measure volt AC You have to connect the dots.
You have to look here.
Here we have the vault.
So I will connect that it way up here and the come on here.
Then I will enter the vault if I want to measure.
Amber let's move.
I will move to Amber.
As you can see here in D.C..
And since I'm measuring 10 am I will.
But the red wire here and the black while here.
These are the wires that I'm talking about.
Let me show you.
These are the two wells.
This is the red and this is the black wire.
The black is usually connected to the common and the red is usually connected to one of these three
depending on the dial that they're movement.
So if I want to merge our heads here as you can see I will go and choose heads from here.
That's it.
Make sure that before moving this from one to another you will turn off that also be displayed because
of your work.
If these two wives were connected to something and you move let's say from words to Amber it might break
your digital multimeter.
So make sure to turn off before moving this wire from one type feeding to another.
That was a quick introduction to how to use a digital multimeter to image out different things.
We will talk in more details about resistors capacitors and doctors and other things but that's it for
now.
If you have any questions please ask the crew on board.
Thanks for watching.
