Hi everyone. At the end of this video, you're going to be able to use the Measure Up digital
multimeter. So this multimeter that we see here has a couple different things going on.
We have our lcd display, we have a hold button, we have our backlight, we have our rotary switch
to change what we want to measure, we have a couple com terminals.
Okay so what do these different buttons do? So the whole button is used if we
want to hold a measurement. The backlight display is used to illuminate the display
So let's go ahead and turn this on. So you can see I want to light that up... I can.
Alright, now let's talk about the different ranges that are available. So right now it's set to off.
From here to here, we're measuring dc voltage. So this first setting measures voltage in the
approximate range of 200 millivolts, 2,000 millivolts, 20 volts, 200 volts, and 500 volts.
So those are different ranges that we have to manually select depending on what range we want
to measure. Okay, we also have a 500 and 200 volt ac setting. We have a continuity setting.
This will test whether there is a continuous path for current to flow. We have a square
wave output that we can send, which is a nice feature. Then we also have
all of our current measurements starting from 10 amps here, all the way down to 2,000 microamps,
and then over here we have our resistance measurements starting at 200 ohms here,
working our way up to 200 mega ohms. So I get a lot of students who don't know or understand how
these access terminals work. They think that it doesn't, or they either don't know what they mean,
or they just leave them how they get them. So, you know, maybe they'll have
the terminal set up like this. They go to take a voltage measurement, and they get zero volts,
and they they don't understand why that's going on. So it's very important. Typically,
under normal circumstances you are always going to have the black
probe connected to the common ground. Now, depending on if we're going to measure voltage or
resistance, sorry, if we're going to measure voltage or resistance, we're going to use this
terminal right here. However, if we're going to use measure current, we need to connect the
red probe to this terminal here. So I'm going to connect my probe to the middle terminal,
and I'm going to measure the voltage of this battery. So we're going to set our
voltage over here... Okay, so here I have a 1.5 volt double a battery. All right,
I'm going to set my voltage over here to 20 volts because that is in the similar range as 1.5 volts.
Okay, now I'm going to connect the black to the cathode, the red to the anode of the battery...
and I'm getting 1.6 volts. So we're looking good. This battery is good, it still has plenty
of juice in it. So we're happy there. Now what happens if I would have had this set to say, 200?
Now what's going to happen is, am I still going to get a reading? Let's find out.
Okay, so I get 1.5 volts still. So we're looking good. Even in this range, I'm still getting
a good answer. Okay, what if I had this set to 200 millivolts? Let's see what happens here.
Okay, so I'm getting open line. So what that's telling me
is that I'm out of range for this particular voltage.
If I go up a notch, let's see if it works this time.
Okay, so right here you notice I'm getting a measurement of 1,610. Now,
that's a correct measurement. The thing about this particular meter is it doesn't give you the units
that it's in. So you have to understand that you are measuring in millivolts. So you have 1,611
millivolts which is equal to 1.6 volts, approximately. So everything still looks
good. Even if you aren't exactly right on your setting, you know, depending on what you're
trying to measure, as long as you're pretty close, this meter is going to pick it up.
You do have to be a little careful. All right, so now let's get a measurement of a resistor.
So right now my meter is off. I'm going to set it to 200 kilo ohms. I know that this resistor is in
that general vicinity. So I'm going to take a measurement of that resistor, and I get 99.6
kiloohms. So I have a 100 kiloohm resistor right here, and it looks like it's off 100
by a little bit. Now what would happen if I would have set this to 20 mega ohms and taken a
measurement? Okay, I still get a reading 0.09. So I have to remember that's 0.09 mega ohms.
0.09 mega ohms is going to be the same as a 100 kilo ohms, or 99 kiloohms. Okay, now if I was at
20,000, let's see what happens. All right, I get open line. See, I've exceeded the
range of what that resistance can do. So 20 kilo ohms is my max value that I can go to.
So I've exceeded that. So I'd have to move my meter up to get a measurement there.
I mean, the same would happen with the 2000 and 200 ohm settings.
Okay so you should...
Okay, so that was the basics of how to use the measure up digital multimeter.
It's a pretty simple tool, it doesn't have some of the auto ranging features
that some of the nicer meters have, but it can do quite a bit. There are some limitations
to the meter obviously. There's certain voltage limitations, spec wise. The meter claims it can
go up to 500 volts. I would personally not trust this meter at 500 volts unless you have a very low
current that you could be dealing with. I hope this video was helpful. If it was, please
