So you have to play with the lines there to make sure that you’re picking it up in there. And even with the digital meter and trying to hook this up, it’s even giving us a hard time to try to figure out what that voltage is. So what we would have is I’d have this outlet here and between my line and my neutral, which are the two top areas there, we should have 120 volts. And what we have our students do is we have our students draw out the outlet beforehand. So what we do is we will use our digital meter. These other things here would be great visuals for the customer after you’ve diagnosed the outlet correctly. So with that said, what we use in the field is either a digital or analog meter, which are going to be the most accurate things for you to check. But again, it doesn’t tell you how much voltage is actually at that outlet. It’ll tell them all the different scenarios and it’s just very easy to plug this guy in right there to see that you have a correct outlet. And when a customer would plug this into their outlet, they’d be able to tell that if they had an open ground or a hot neutral reversed, hot ground reversed, open neutral. The last one that we have is the outlet plug tester with what they have out there. But instead it has a little lever that will beep and let you know where your voltage is at, whether it’s 120, 240. And again, it’s just sticking it right into the outlets here, just like you would a meter. Technicians will also use this voltage detector here as well where it’ll just tell you if it’s DC or AC voltage, whether it’s 120 or 240 volts. I can rub it up against my sleep and generate voltage that’s just from static electricity. So this is very inaccurate and it shows not only the inaccuracy, but it doesn’t show you the voltage reading there. I know that this outlet is correct and we’ll be able to show you that. I just went into the ground and it gave me a beep and I know that there’s no voltage on the ground. What this does is this is a stick that we should be able to stick right into the outlet here and wherever we don’t have voltage, we should not hear that beep. For instance, we have what’s called a foreign voltage detector.
There are a lot of helpful tools out there that can help you check outlets and voltage.
So we’re going to show you the ways that we do it here with the students and what we suggest even in the field with your veteran technicians.
