Beginner Electronics – 11 – The Multimeter

what's going on everyone my name is Kota Moore and welcome back to electronics episode 11 in this episode we are going to talk about a very important tool that

you should use whenever you're doing electronics work and that tool is the multimeter now it's not an absolute necessity to have a multimeter whenever you're doing the electronics work

however having a multimeter and knowing how to use it properly can help you a lot whenever you're building a circuit for instance if a circuit isn't working properly you can use your multimeter to

help discover the problem and hopefully fix your circuit much faster than it would take then if you didn't have a multimeter so I highly recommend getting a multimeter even if it's a fairly cheap

one and doesn't have many functions to it so what exactly does a multimeter do well a multimeter allows you to measure certain values of different things inside of a circuit the most common ones

and the ones that you should have are the ability to measure voltage ohms or resistance and amps or amperes those are the basic functions that you should have on any multimedia that you get many of

them come with a lot more too for instance this one even measures Celsius and degrees Fahrenheit temperature as well as frequency and a bunch of other stuff but you don't really need that for

this series now if you do go out and get a multimeter I highly recommend that you get an auto-ranging multimeter as you can see this multimeter even says that it's auto-ranging right at the bottom

there now auto-ranging basically makes it so that the multimeter performs all the hard work for you and will measure your value perfectly whereas a non auto ranging multimeter means that you have

to whenever you're trying to measure something in put a manual range for the multimeter to work with and you don't want to have to deal with that so I highly recommend getting an auto-ranging

multimeter that measures voltage ohms or resistance and amps as you can see this multimeter has the dial for what I'm going to measure as well as a digital screen and it also comes with two probes

these are called test probes it comes with two often now these test probes are what you actually plug in to your circuit to measure whatever you need to measure and as you can see these probes

plug right on into my multi now I'm not going to go super far in depth about multimeters in today's tutorial but I will show you a few basic functions of one and just the general how to use one

for instance I have a 9-volt battery here say I want to measure the voltage of this battery how much voltage does this battery actually have well with a multimeter that's

these simple to do first I'm going to turn my multimeter on to the voltage measuring position that way I'm measuring DC voltage next I'm going to take the battery here and look for the

positive terminal and I'm going to put the red probe on the positive terminal of the battery like so and I'm going to put the negative terminal on the negative terminal of the battery as you

can see the multimeter is now going to start measuring the voltage of this battery in this case it's reading eight point eight nine so just below nine volts that's not too too bad it's as

simple as that to use a multimeter you put the probes between two things that you want to measure select what you want to measure like resistance or voltage and we'll I it'll give you the value now

it might not seem too too useful right now but as you begin building complicated circuits it's going to help you out a ton for instance let me turn this to the ohms position this way I'm

measuring resistance in ohms as you can see it's reading oh L right now for open leads and I'm going to show you that we can even measure the resistance of a body using a multimeter if I just touch

my fingers whoops to either end of the probes you'll see that the multimeter will begin reading a random series of numbers that's going to approximate the amount of resistance

that my body has between the two connections it's going all over the place here but it's looking like a hundred and fifteen kilo ohms and of course it works the same way with a

circuit so you can even measure the resistance of a resistor if you wanted to again I highly recommend that you have even a very simple multimeter at your disposal to use whenever you want

and I recommend that it be an auto-ranging multimeter thanks for watching everyone and I hope to see you guys in the next electronics tutorial

We talk about the important Multimeter tool and use it!
