Multimeter meters multimeter is a device that most electrician and electronic geeks use to get results
or measure voltage current and test electronic components.
You must buy a multimeter with the following requirements.
So the required features the minimal required features is that your multimeter must measure up to 50
volt DC DC stands for Direct count and it can measure up to two hundred fifty volts AC AC stands for
alternating current.
It must also be able to measure resistance or continuity for testing purposes.
You must also get your multimeter with these features.
It must be able to measure entry level current to approximately 250 million arms.
Also be able to measure DC and AC current up to 10 amps
as you can see.
These are the more the two most common types of 1 2 meters.
The first one is the analog multimeter and the second one is the digital multimeter.
You can recognize them by very simply as you can see that digital multimeter has a digital display that
overlays numbers while the analog multimeter doesn't have a digital display.
Basically have an analog that moves on a scale.
So the advantages of another 20 meters is low cost.
While the advantages of digital multimeter is that it's easy to read more value and more accurate readings
because it gives you direct numbers where in this case you might sometimes have to guess a number between
two dashes
now when it come to this advantages for the analog multimeter.
It's difficult to read measure value and you need to start at highest range and work way down to suitable
range which means that you don't have a specific range to test your equipment or there is no automatic
adjustment for the analog multimeter.
You have to start with the highest possible value and then move down to other values that this advantages
of digital multimeter is the high cost and you need to start at high strange and work way down to a
suitable range.
So these two have the same advantage.
You need to start at the highest possible range and move down to lower ranges.
But this one cost our much more than this one.
This one is difficult to read and this one is easier to read.
What we recommend is digital multimeter because it's a way much easier to read and you don't want to
waste time on trying to figure out the value that you are reading.
So nowadays most multi meters comes in digital analog quality meters are used in our air much less volume
than before.
Now as you can see this is a digital multimeter that's used to test this model.
And as you can see it has a lot of features.
The most important one for us here is the auto ranging feature its original multimeter.
It's the third time.
But that digital multimeter is away much better than this one.
It has a feature called Auto ranging and from its name auto arranging means that you only need to set
the thing that you want to measure.
As you can see in this data we want to measure volt AC or volt DC and it will automatically get the
result that we want.
And this is what auto ranging means.
It doesn't have different ranges of values and we don't need to start at the highest possible value
and work our way down or what we need to know to do is set the value to the
thing that we want to measure which is here Volt or Amber or current and it will do the job for us.
The disadvantage of this is obviously the high cost it costs our way much higher than these two because
it has the will to ranging future but it saves you a lot of time cause using these two you need to start
at high strange and work your way down as you can see here.
We have DC umpire or Charon.
You have to start with the highest value and keep moving down until you reach the range or the required
range.
While in this one the third time which is auto arranging multimeter all what you need to do is set the
quantity that you want to measure and it will auto range that value to the correct range.
Internally you don't have to do anything in your dial and you don't have to adjust anything so it will
save you a lot of time.
But again it will cost you alot that's it.
We have no clear idea about the three multi meters and under 20 meters digital multimeter and auto arranging
multi meters or auto arranging digital multimeter is the best one or the most effective one is the auto
arranging digital multimeter because it saves you time by doing the auto ranging automatically internally
so you don't have to auto arrange or start from the highest value and move down to the lowest value
while the other two you need to start at the highest possible value for current or voltage and move
your way down to get the correct range.
That's set for this lesson.
Go and buy the one that fits your budget and your time.
What we recommend is auto arranging multimeter and we'll show you that multimeter in the practical section.
Thanks for watching.
