Hello this is the review for the RioRand

power meter plug. I bought it on Amazon for $15 US this is an energy meter that

helps you to monitor and test instrument it determined the power consumption and

electricity cost. It can measure the voltage, ampere, power factor, power

consumption and current power. I believe it was made in China

so don’t expect a very high quality but it does what it have to do. It came

with a simple manual and that’s it. I wish they were a little bit more

instruction because I had to find out how to put the cost consumption and I

will show you how to do it in this video also I will show you how to calculate

the kilowatt and to know the price per year, per month or per day, later on the

video. Now first thing first when you open a digital power meter

it’s important to just reset the unit to make sure that we don’t have a old

data from their testing so I just use a pen and it resets automatically. so now I

have plug one of my light, it’s been plug for an hour and six minutes this is

how much it consumed it say 0.022 with that you can calculate how much

your device consumed per hour. Option this is the voltage, the hertz, the ampere

and the power factor the power factor is a unit to say how much efficient it

distribute electricity this is the lowest peak of the light, this is the highest

peak of my light and this is currently how much my light consume so it’s at 20 watt

so let’s say you want to put the cost over here you press this button cost

and then you press again you hold for three seconds this will blink all you

have to do is press the function so it is at the first digital the second

digital and here you can press up and down like so and then once you are done

just press cost and that’s it alright so now for the calculation the

first thing you need to know is how much your electricity bill cost. So in

North America it goes in general on average, I’m just doing an approximation it’s 15

cents per kilowatt the second thing you need to know is how much what your

device consume so in my case is 20 watts so you take 20 you multiply this by the

number of hours so let’s take an example 8 hours you divide this by 1000 equals

16 kilowatt and then you take the 16 kilowatt multiplie by 15 which is a

average, equal 0.24 so that means it costs 2 cents per day and then you take

0.24 multiplied by 30, equal 0.72 that means it costs 72 cents per month and

then you take that 0.72 multiply by 12 equal 8.64 so that means my

light in my case, it costs $8 approximately per year. So there we go I

hope this really helped you it’s like I said it was really simple

if you have any question please go on the comment section and I will do my

best to reply so there we go I hope you like this video, please give a little

like it helped my channel so thank you for watching bye

The manual, if it can be called that, is garbage. Really appreciate this as I was almost set to return it. Thank you.

Thank you very thorough! 🙂

What happens when you unplug the light fixture and plug it in again? Does it continue to accumulate the power usage?

Excellent! Thank you.

What does the low and high mean?

It’s made in China so it is really high quality he says lol
