In this video we are going to know how to take advantage of this tool that will help us a lot from now on
young how are you? Edgar here again greeting you, I hope everyone is well, how is that quarantine
I tell you that here in Guatemala the president spoke yesterday and said gentlemen, I will stay at home 15 more days
so we are going to stay at home 15 more days, the good thing is that we have a lot of work. There are sorry for not uploading yesterday's class, but I'm working on a project there and soon they will know that I have prepared there
I don't want to take your time, we are going to enter today we are going to be looking at the multimeter
Let's remember that this course is of a fairly basic level, what we are trying to do is to have a good foundation, so if you can use the multimeter enough, you already understand enough then go see some repair videos that we always have on our channel
so that he also learns a little more or refreshes himself or has a little fun, but for you who are just starting we are going to talk about the multimeter
The question we always ask ourselves is, which multimeter to buy? What multimeter do I have to buy, look preferably personally, if you can buy a autorange multimeter
what do you mean of autorango? For example I want to measure voltage, I only put in volts that we are going to learn a little while
and the multimeter alone detects what voltage it is, if it is 3 volts, if it is 50 volts, if it is 110 volts, etc. The lonely detects it, an autorange
these are the digital multimeters that we are going to see, they are autorange multimeters
So I recommend them, now there is a lot in the market, if you have not visited our page EdgarYoReparo.com click on it where it says Edgar recommends and there we have a lot of tools that we have tried and can serve you
I am not telling you to buy it from there, apart from not selling it I am just the links but you can quote another type of multimeter
preferably it is autorange and if they do not have autorange we will have these here that we have all the ranges we have to put for example if I want to measure 50 volts I can not put it where it says 20 if not I have to change it where it says 200 because it means that there it measures from 20 to 2...
that with regard to which multimeter to buy, but they do not necessarily have to use one of these, the link is on the page
Why do I occupy one of this? for the ease of connecting on the computer, the interface is very good, very easy to use, etc.
It is a good multimeter, the price of these is more or less for about 80 dollars plus shipping, so it is not a somewhat economical multimeter
there are other types of multimeters
you really don't have to buy a brand name one
It is not that they are paying me to buy it, there is also the link on my page, but it is a very very good multimeter
So that answers the question of which multimeter to buy, preferably buy an autorange ok, autorange is much better or is easier for those who are starting than one of these because when it comes to measuring resistance, measuring amps these get a little complicated
then we will go to see the functions of the multimeter, we will see what functions it brings and what functions we are going to occupy
So that responds to which multimeter to buy? they don't have to buy a branded multimeter, they have to buy a functional one, now if they have the possibilities to buy a good one then take it
the multimeter will be the first tool with which we are going to start getting into measurements, with this we are going to start making voltage measurements, current measurements, resistance measurements, diode function, continuity function among other things
Those 5 things nothing else, we are not going to be doing more with this device, there are multimeters that bring for example a thermocouple, to measure when we are calibrating the heat gun that if we are going to occupy it
there are others who bring gers that we will not occupy
then only the 5 that I just told you, current voltage, resistance, diode scale and continuity
To start with the multimeter we will see several buttons here, I will start first
This is to change the function, the function that we need depends, so we move it depending on what function we need
these that are here are all the functions that our multimeter gives us
your multimeter, depending on which one you buy will have something that says function, with this what we are going to be doing is that when we are in an area that is multifunction, we are going to be able to choose which is the function that we want the multimeter to do
maximum or minimum is for example when we are measuring any measurement we are making of volts, amps, resistance. The multimeter if we set it to maximum will keep the highest measurement that it found and the minimum with the smallest measurement that it found
These are very useful for example when we are going to measure lines that the voltage only appears in a matter of seconds we can set it to maximum so that our multimeter captures the maximum value and leaves it captured because sometimes it is so fast that we cannot see
then these would be the functions, maximum minimum
and this hod, is for example, all the multimeters are going to have something that says hod, it is to stop the last measurement, you can stop where it says hod
An example that I am going to show you, that I did not want to go to the tips but for example if I am playing this and press hod it stays where I captured it, exactly where I captured it and there it stays
so that would be where it says hod, if I keep it pressed the light of my multimeter turns on, I just learned that right now
we have range and what it says to connect USB this is centigrade and fahrenheit because my multimeter also brings to measure temperature
This is going to be very important for when we are calibrating our heat station, so we will start to see the functions
first we have the function of volts, this also measures what is the volts in alternating current in direct current, we will explain that in some lessons laterfirst we have the function of volts, this also measures what is the volts in alternating current in direct current, we will explain that in some lessons later
volts, we have millivolts, why? because we agree that a value when it is below 1 volt for example, we already have to start measuring in millivolts, so milli volts in both direct current and direct current
we have a function of hers that we will not be occupying this
We have here something that is a multifunction, a section that has multifunction, as well as Edgar multifunction? What does multifunction mean?
When you are here, all the multimeters bring it, I'm going to go to the other multimeter. when you are here you are going to measure diode scale, there appears the symbol, continuity scale, it also appears to you to measure capacitors and to measure resistance or a resistance itself, which in this case would be ohms true
then diode scale that basically we are measuring the voltage drop, continuity scale that is actually a resistance too but it is a sound resistance between a range of 70 75 ohms
and when it is in that range the multimeter what it does is beeps, from 0 to 70 ohms more or less
and these are the 3 that we are going to be occupying, the detail is that when we are in this function we have to be very careful because if we see the multimeter I have it here in multifunction but here in the corner it is in ohms
With the function button, what I do is change it, and right now I will change it to another function that is continuity. If I turn off the button, it goes to diode scale.
If I change it now it is set to Farads, we are not going to take this up either, and if I change it again it is set to ohms
then this will change depending on the function that we want to play, this is the temperature, as I tell you my multimeter brings to be able to calibrate heat temperature in this case of my heat station
We will not be using this function here, and then we will enter other functions that are amps, everything A says, here we will be measuring microampers, here we will be measuring milliamp and here amperage
So that would be with the functions, now our multimeter brings these various places where we can put the tips
the first is mass, which has been negative, the negative point of its multimeter will always go to mass, it will always go where it says with truth, that this is being negative
Now because we have several reds, what is the difference between them?
first we will have a red, here we can measure various things, we will be measuring the volt function, we will be measuring the ohms function, the diode function, the continuity function, all those functions here says them
so if I wanted to measure voltage for example I will always have my multimeter here, if I want to measure resistance, if I want to measure diode, if I want to measure continuity, if I want to measure millivolts, if I want to measure volts always here
So why bring these two, why bring those two more, this will be to measure the current. Let's remember that we are measuring the current that is passing through a circuit, we will see later how we will be measuring that
the multimeter will be able to measure between milliamps up to 10 amps, let's remember that the multimeter on the inside has a fuse if what we measure consumes more than 10 amps then what will happen is that the fuse will burn and our multimeter will not work
It is not that it will go bankrupt, only that our fuse will burn out and we need to change it.
This would be for these 2 options given here, for milliamps then I would have to put on amperage, here it is to measure what has been from 1 ampere to 10 amperes maximum says here
So here depending on the amount of current that I want to measure, I will place it here. this is basically for amperage
so this is an autorange multimeter now let's move to a different multimeter
So what we have here, we have the points, we have mass that is what earth would be like and here we have the positive one to measure voltages, current, milliampers, it also measures here, continuity, etc., ect. everything we want to measure here
and here it is to measure up to 10 amps of direct current, then again the same tips
Now the difference of multimeters like these is the following, these multimeters are not autorange, which means that, we will start with the easiest, first we have the diode function and continuity they have it in one place
for example this if I put here what is the negative and here the positive
I touch
and this automatically measures me what is continuity and voltage drop in diode function at once, we don't have to select it ok
We are going to go into a little more detail, now, we are going to go here where the continuous voltage is, what does this mean, does it mean that it starts from 200, 200 millivolts ok
this means that it will measure me from 0 to 200 millivolts so if this goes beyond 200 millivolts I have to know and I have to change it for what is 2000 millivolts
2000 millivolts is being 2 volts in this case, this will measure me from 200 millivolts to 2 volts
then if I am going to measure from 2 volts to 20 volts I have to put it at 20, why? because this measures from 2 volts to 20 volts, now if I know that what I am measuring measures more than 20 but not more than 200 I put it here, now if what I am going to measure measures more than 200 but not more than 600 I measure it here
so this is the difference if you realize in these multimeters what you have to be changing are the measurement ranges
and that's why this type of multimeter is a little tedious so much to speed up our work
the same for example if I go here, everything that has to do with resistance I am going to measure from here, 2 milliohms, 2 kiloohms, 20 kiloohms, 2000 ohms, 200 ohms. so this I have to know exactly what I am measuring to be able to change it
The same with amps, I start at 200 microampers if what I measure measures more than 200 but not more than 2000, now if I am going to order something more than 2000 I pass it from 2000 this will measure from 2000 microampers to 20 milliamps
If what it measures, it measures more than 20 milliampers, I have to pass it here because it will measure from 20 to 200 and this one will go from 200 milliamps to 20 amps. so this is the difference in a multimeter of these that we have to select the ranges
That is the ease of having a multimeter of these that are self-ranging and apart, for people who are starting it is recommended to start with one of self-range to make things easier.
Ok gentlemen, then this is the introduction to the multimeter, the multimeter is not a difficult thing, we are going to learn the measurements in the following classes, this was only the introduction to the multimeter, what multimeter to buy, what functions does it bring, what is the difference of a auto range meter to one that is not auto range
and in this way they can start to move their multimeter there, so in the following lessons we will start with the measurements on the multimeter so that they start to get the juice out of this device
gentlemen for me always a pleasure to greet you, always wish you the best, I hope you are well I send you a big hug and always happy to be greeting you again
see you in the next video or in the next class of this which is a course a basic mini course for all those who are starting
At the end of this mini course, I am going to send you a link so that you can download some electronic books and start reading a lot.
Sirs! for me always a pleasure, care a lot and see you soon. Bye
