Okay, we're going to put three of these nine volt batteries in series ating as I stated previously, so I'm going to get my clip leads and I've tipped the batteries up and we've got as far as the polarity of the batteries, minus and plus, minus and plus, minus and plus okay. So, I'm going to go plus on this battery, clip it on to the negative terminal of the next battery, which is that one and we need one more clip lead And here we go. This one and right here. And let me look on the monitor and see if you can see that and I believe you can. Let me just move this up. There we go.

And let me get this one here. All right. So minus and plus, minus and plus, minus and plus. So we're in series ating. So again, let me turn my meter on. And as you know, previously, what do we have?

We have on this particular meter when it comes up. All right, it comes up In AC voltage, I have to hit my selector. And if you see here, right there, if you can see that it's, it's a line meaning DC. Also notice the auto. Alright? The auto states that the meter will select the best range for me.

And for the most part, when I'm using this meter, I kind of leave it on there. Alright, it's really, it's really the best. The best to do unless I need to change something. I just did that previously, just to show you how it would work. So let's, let's measure the voltage and I'm going to try to do this without knocking anything down. And let's see what we get.

And we get 29.4 volts. Again, it's a little bit high. Ideally, it should be around I believe it's 20 Seven volts, three times nine is 27. Okay? It should be around 27. But since we have no load on this, which we'll demonstrate when we talk about current, the voltage will be a bit higher.

Okay, and I just watched a clip lead. And let me put that back on. Alright, so that's pretty much it. And seed. Yeah. Now what happens if I reverse my leads?

And I get a negative, that's all. That's all the polarity of the battery changes, I mean of the meter changes. So Alright, so that's what we've done. Um, you know, that's pretty much it. I suggest you do that and get familiar with your meter. All right.

It's this is not Very difficult lab, but it will give you an introduction to a multimeter. All right, as far as the voltage range now on the next section, we're going to talk about current flow. We're going to measure some DC current, and that'll be the next function on the meter. All right, oh, wait a minute. I forgot I got to do one more thing with you. If you look at the slide, we're going to do one, we're going to put one of these batteries in series opposing so let me before I go, let me let me do this one here.

All right, so I'm gonna take this here and I'm gonna go series opposing. Alright, let me let me put this back here. All right. So now what do I have? I have minus and plus, minus and plus plus minus. So these two batteries right here are in series of posing.

So ideally what should we get? Well, let's see. I'm not gonna tell you, you tell me you think about it, and I want to get the right polarity. Alright, so there's my negative and survey says 10.25, which is right, because ideally it should be nine but since we're not drawing, we're drawing very, very, very little current, the voltage, the terminal voltage is going to be high, so therefore we're good. Alright, so there you go. I hope this took some of the mystery out of a volt meter.

And again, watch for the links because I'm going to put the link up for the volt meter, the clip leads and in Anything else that I may use in this lab and if you so desire, you can click on it and get it. If not, feel free to get in any place you want. Okay, you take care. We'll see you in the current section. Bye bye
