How to measure AC Current Draw with a Clamp Meter (DT3266L, AC Amp clamp, Multimeter)
HTML-код
- Опубликовано: 17 окт 2024
- Usage: The amp clamp meter has to be used on 1 single wire, not on a cable which has 2 wires in it! Place the clamp of the meter either around a phase wire, or around a neutral wire.

We cannot (at AC voltage) measure power by multiplying voltage and current. If we multiply them, we will get apparent power (with VA unit). At AC, the voltage phase can be different compared to the current due to inductive or capacitive load.
I did science in my high school, long time ago... So how do I measure (consumed) AC power with a clamp multimeter? In a test situation I need to compare variable power settings of an AC ventilator (axial or centrifugal compressor) with different outcomes of my air-thing-contraption ;-) I would be grateful for any help here!
Respectfully, aren't you grabbing at hairs here to make an kind of off subject point about power consumption? The clamp is for current draw mainly so if you see a non typical current that's all you need to point to the device as suspect. ? how different is the apparent power from what you'd read with the meter?
@2 liter His point is that what you’re seeing with the meter is apparent power, the real power is somewhere lower than what multiplying the measured current and voltage would indicate. The more inductance/capacitance you have in the circuit, the bigger the difference between apparent power and real power.
But you’re right, the clamp meter isn’t supposed to be used to calculate your electrical bill, it’s supposed to let you troubleshoot problems. So the difference doesn’t matter that much in the majority of situations. It’s just something to keep in mind when measuring circuits.
P = V x I x Cos Ф
single phase AC
use a watt meter than, kill-a-watt or a knockoff
The BEST explanation of the clamp meter I've seen on the YT!! No talking is a bonus!!!
this is a very good video. clear and not muddied up with a lot of unnecessary talk.
Really really good no talking just straight to the point
I don't comment a lot, but I had to say this: it was funny to see how many times you've told us to use it around only 1 wire. Excellent video! This was the second in search results. Also good that you've shown home appliances results.
Bought one. Tested by directly clamp the cable. Zero number. I thought it's a defect one. So I search youtube and find your video. Informative, comprehensive but simple! Thanks!
what i like the most is the transitioning wire, brilliant
Really nice tutorial, action speak louder than voice, thanks man!
Man, this is a great video! I am a construction manager, running big industrial projects but am sadly clueless about electricity, thanks.
Nice video! This helped educate me on how to use my Aneng ST207 Digital Clamp Meter. I have tried searching on how to measure the amps using my clamp meter and lead me to your video. As I want to measure the amps and the number of hertz on my 1.5hp inverter airconditioner, but was getting around 0.0 amps and 0 hertz. Your video has taught me to correctly find the amps and hertz by using either one of the positive or negative wires and not the whole single wire which includes both.
thanks, I didn't know to go around just one of the wires, was confused that everything was near zero
Excellent Video! Excuse me for the intrusion, I would appreciate your thoughts. Have you researched - Franaar Shining Shape Formula (search on google)? It is a great one of a kind guide for revealing the secret to repair your electronic devices minus the hard work. Ive heard some extraordinary things about it and my work colleague after a lifetime of fighting got amazing results with it.

I like how you straight jump into it with no intro. Really helpful and easy to understand concept. But i would like to ask a few question:
1. How to make the adapter that you split the neutral and live wire?
2. Can i measure directly using the clamp meter at the live wire after the mcb at distribution board? Or would it be unsafe?
3. Could you suggest a cheap but ok brand model for the clamp meter for home use..
Thanks in advance sir
1. It's just a simple cable with a plug and a socket ► ruclips.net/video/x_RbRM1QySQ/видео.html
2. If the wire is insulated then it should be OK...
3. Not really, I bought the cheapest one from ebay, but the more expensive ones can measure Direct Current Ampere also!
I like how you are considering all “test cases”. Thanks
I have a lot of wires in the cellar and I don't know which goes in which room. Any chance I can find out without splitting the wires? I don't want to measure how MUCH current is going though...I just want to know if there is current going through or not. Is there a way to do this without splitting the wires?
I am not an electrician but my electricity consumption suddenly spiked 57% up for no apparent reason. I am wondering if the aircon is clogged resulting in more power draw, or something else has caused this. Thanks for the video. I learnt something!
Wow bro!, thanks for sharing the video, now I can check ac drawn from appliances using my clamp meter.
A perfect demonstration of what the title is. Well done.
But wish you would add another clip and describe the other functions of this clamp as that is where my problem is and this tool is not showing me any reading or continuity check.
Any ways thank for your demonstration of correct draw, especially emphasis of how to check only one wire at a time, to see the reading and not both (That two way current cancels each other with a net reading of zero, so wrongly user thinks this tool is not working).
Thumbs upped and you have one more subscriber.
For continuity use the resistance part of the meter (2K, 200K, 2M Ohm).
Hello Thank you very much for the video. I only have a question. I have seen like this an LED spotlight that has the symbol of an arrow curved to the right. What is this for? because I see that also in the options this symbol is repeated together with a lightning bolt could please help me understanding. What is this option for? Thanks
I saw money video of clamp meter i couldn't understand how to use it when i saw this video now i understand how to easily use it becoz in this video show pracitcaly
just bought one of these for finding out the watts of my tv/ps3 so I can use my inverter when the power goes out.. great tutorial . thank you.
Clamp meter with temperature probe
rodolfo jimenez
Why do I need temperature probe?
Is there a way to use these Clamp Multi Meters to measure Wattage by using the clamp but not bare wires?
I like the idea of the shorter split extension where you can check it there rather than messing up the appliance cord. I was under the impression that you can clamp around both wires (as I've never actually used these types of meters), that is kind of inconvenient that both wires cancel out the reading..lol
So what are these meters really for then? Taking readings in electric panel and other single wire leads?
You can also measure the PC's power usage before and after starting a game.
Learned something new today. Thank you for sharing.
Would this work when trying to measure the current going through a drill connected directly to an AC house outlet in the US? Is there any modification of the code that would need to be made?
Perfect demo but no need to go over the same thing time and time again 😊
best video for new clamp user !!!

So Maybe a dumb question, but Will this work in my car to measure dc current?
If you use a more expensive DC amp clamp (the one shown in this video is for AC only!) and place it around just one (1) wire then it should work.
@@furulevi thanks. Got one that can take ac and dc and it works well 👍
How is this of any use measuring say a line from a panel if i want to know how much power my water heater is using? I cant split the 240v wire from the panel to tank. My meter shows 0s no matter what setting i put it on
Can i ask something? I just want to know what is the thunder symbol in the middle, and what it is for, or what is the use of it?? Thank you
Some one had this clamp multimeter but didn't know how to measure by hunging, just we thinks that it is used for hundling or to hold it up.
Thanks.
For calculate the exact watt and better accuracy we multiply amps with the finest providing voltage OR after loaded voltage? Bcz there is a variation and voltage get redeem after the load and it down like 225 to 215. Kindly tell me now which voltage we will take for multiplying with the watt?
Theoretically the voltage (220V) from the wall socket should not drop after a load is added, but if you are powering a device from a battery than it will drop. In that case multiply the lower voltage with the amps.
furulevi thanks a lot bro, but i have checked it that after load voltage get drops. AC voltage and as well as my inverter voltage so i was confused
furulevi powering device from battery to you mean through Inverter??? As i think
Is the power that you have calculated is in per second right? how about if you calculate it in terms of per minute and per hour, should you multiply that power calculated times 60 for per W/min and another times 60 for W/hr ?
Yes second. That would be logical, but it doesn't work that way. They name changes from Watt to Watt-hour and it can be confusing. For example if a device uses 1kW (in 1 second) is left running 1 hour, than it would consume 1kWh (kilo Watt hour).
If a 60W bulb burns for 3 hours, than it consumes 60W (power) x 3 hours (time) = 180 Watt-hour (energy)
Power x Time = Energy
kilowatt-hour is similar to a grouping method. For example youtube at every 1000 thumbs up it shows 1K, 3 zeros are turned into letter K, and kilowatt-hour at every 3600000 Watt-second is showing 1 kWh. (3600000 is the number of seconds in an hour multiplied by 1000 because it is Kilowatt)
furulevi ok2 now i understand thank you :)
what if in a given situation, i have fluctuating values (increasing and decreasing) current sensor readings per second on my data log. To obtain the exact/accurate value of kwh, should i all the values to obtain it, that is about 3600 current sensor values?
Thank you for the no bullshit video.
Wow, thank you so much for producing this video! I was thinking my clamp meter was not working until I learned about this.
Now, how does that convert to watts used per hour?
A cool device to find on sale is a Kill-o-Watt plug in unit. Mine has a memory and meter function, so can run an electrical device plugged through it - to get the total average power used. Great for things that have a thermostat or compressor that kicks in and out.
General question: On a DC clamp meter, does shielding around the wire influence the measurement?
I'm not sure, but I think not...
Yes I think so. In DC mode, its the clamps which are passing small AC and creates dynamic flux from there. A shield around the cable will change the vector of the field causing errors. It won''t straight up "shield" the inner wire into an insignificant wire w.r.t the clamp, it would just change the direction so that opposing fields do not impede the wire. Similar reasoning for double shielding: one shield around the wire, another shield in relatively external environment.
this is very very nice video.I have the same meter too.please explain the hole functions of this meter like AC voltage, DC voltage, AC current, DC current, resistance, diode, frequency, temperature, and live wire test.please do it as soon as possible.thanks a lot.
This device does not support measurement of: DC current, diode, frequency, temperature, and live wire test.
Am i correct or not?
Please clarify my doubt
In terms of AC line. There are hot(main) line and neutral line.
As we know in the Postive cycle hot(main) line carry +230 Voltage.
my question here.
which line carry or cause of -230 Voltage in Negative cycle?
if it is hot(main) line, below statement also true.
so, in the positive cycle current flow from hot line to neutral line ,and in the negative cycle current flow from neutral line to hot line because of potential difference. we also know that electron flow opposite to current flow.
As I know it is similar to the chain on a bike, while on one side the chain moves forward, on the other side the chain moves backward, and than it reverses, backwards-forwards. This forward-backward movement is repeated 50 times in the case of a 50Hz power line. So theoretically both hot and neutral are used to carry the power, but as a personal experience, I once unplugged an electrical heater from the wall socket and only one of the 2 plug rods were hot (high temperature), the other one was cold (low temperature)... Neutral is also connected to Ground, so maybe that also influences something, I don't know exactly.
Positive wave means that you power in the load and negative wave means power returning to source. Of course that's for AC.
I wonder what can be done yo be able to measure a.c. current without needing to do around one wire. Like a slow down

Thank you very much for the informative video.
Quick and to the point...learned a lot...thanks!
Sir Can we check DC ampere with the help of AC ampere meter how much the reading will be different..plz reply me
For example, when we check DC amperes, what will be the Ac meter and DC meter readings?
I haven't tried it with DC, but those meters that measure DC current also are more expensive.
This is one of the best tutorial, I have same model but when I read the manual I didn't understand anything, can you please tell me, how I can check the continuity mode?
For continuity you can use the resistance, ohm sign (Ω).
Thanks, I got it
How does the live wire test work?
would it be possible to make a video explaining how to do it?
Just put the clamp around 1 single wire of the cable.
Hello sir , can I know why we need measure using one wire ? Why can't both as the wire manufactured ?
If you measure 2 wires than the 2 currents will cancel each other out. It's like +1 and -1 = 0
The alternating current in the hot wire is 180 degrees out of phase with the current in the neutral wire. With both wires in the test loop, you read zero current.
Nothing Learned By Watching This Video.if explained about all readings n probs then it will b awsome...
Lol bro, it's a pretty obvious and perfect video.
Which field are you from, arts?
Thank you sooo much
You helped alot for my assignment🌸🌸🌸💐💐💐💐
The extension wire with the wire split is a good idea. Whats it called? I want to buy one or did you make it yourself?
It's called an AC current line splitter.
Thx for ur great video bro..Hats off
With this meter I can not check AA & AAA battery 1.5v Dc volatge , THIS METER has PROBLEM , for measuring 1.5v dc
My meter always measures with around 1-2 volts less... so probably that's why it can't detect the 1.5 volts of a battery.
so. I have to split fire line and neutral line to test it?! :(
very powerful lesson learnt today
Ok 👌🏻 it’s a nice explanation
Would you please tell us the difference between a dryer that consumes a 400 watt and another one consuming 1600watt! Thanks 🙏
The difference is the generated heat.
furulevi
🤔 ??
You know, I read several professionals sites on use of the clamp meter and NOT ONE OF THEM SAID AT ANY GIVEN POINT IN THE TUTORIAL... That you only CLAMP ONE WIRE....
It's very informative. Thanks!
Very helpful!
Creative video, thanks for sharing :)
It's very good video! I really enjoyed and helped for me! Thanks!
Thanks
What about the DC system? And Om
DC amp measurement requires a more expensive clamp meter.
Love the vid by the way
the best thing of this meter is that it shows even light ampare rating like 10-20 watt load also instead it other meter doesn't enough low load in this price cost.. m i right bro?
Thanks a lot man. Easy to understand
Very helpful, big thank you
I really thank’s 4 this tutorial.im learning a lot

I've 3 regular DVMs, but I've wanted to learn how to use a clamp multimeter. 🤔
So i was dumb , tried to measure around 2 wires , but nothing . I thought that the multimeter was defective . Thanks for the idea .
Very helpful 🙏🏻🥂

I think all background music should be outlawed in videos.
Where can you buy one. Thanks.
I bought it from www.ebay.com
how to test capacitor using this clampmeter
Thanks 🙏! That was amazing tutorial
Does it shows the direction of current or not.....? ??
If yes, How
The direction is changing many times per second because it is measuring Alternating Current (AC) at 50 or 60 Hz.
@@furulevi u r correct... But I am asking that if there are some 2 points.. Suppose A and B, then whether the current is flowing from A to B or B to A?.... In that sense does the Meter shows the direction??
I appreciate your reply!
It has a minus sign on the display in front of the numbers (visible at 0:05), but at 1:05 on the left wire is showing 0.03, and at 1:15 on the second wire is also showing 0.03, no minus sign there... so I'm not sure what is the minus sign for.
@@furulevi OK thank you..!!
Hi bro can it use for dc?for see solor plate ampares?
This cheaper model is for AC only, those that can measure DC also are more expensive.
hello sir..ek question hai...
iss multimeter ...mein capacitor ko kaise check karenge ?
I'm not sure what you're trying to ask, please use at least Google Translate ► translate.google.com/
Hello Sir ... there is a question ...
How will check the smd capacitor Farad in this multimeter ?
?
?
This meter does not measure capacitance, but you could use resistance scale to check for a short-circuited capacitor.
can u give me some source ...to check how resistance scale work in FARAD
Great soundtrack.
Can u measure earth leakage on this

can it measure range from 0.01 ampere, 2ampere or 3 ampere
yes
It helped me so much
Thanks for your program.
With the shown demo, can anybody answer this?
What is the max current flow of a 220v then?
That depends on the fuse of that house.
Good video thank you
don't we have to add ground wire ?
That will cancel out the signal and the meter won't show anything. (It is like +2 and -2 which is 0)
@@furulevi thanks for taking the time replying me, much appreciated.
so, i am not a professional, learned almost everything from videos like this.
the way i see it, ground is to prevent electric shock, so when the current takes an unwanted path and goes through the path with less resistance (ground) there will be a surge and the fuse/breaker shuts down.
I am not sure how to interpret what you said.....why would ground cancel out the signal?
if all good, only live and neutral are in use and i only clamp on one of these wires.....
please tell me how to measure leakage current...
Thanks so much!!! You saved me 20 bucks
Is it measure voltage?
Yes, but only using the cables/leads, not through the clamp.
@@furulevi i try to measure amps through wires in my multimeter, ground and red wire in amps slot. After switch on, the supply fused out. What is the reason?
Very good bro
Well done
Good job
Thanks ticherអគុណ👏
I came here while searching Whether my hybrid inverter is ok or not.
It draws much in phase wire and less in neutral wire.
Once when I unplugged an electric heater from the wall socket, one metal rod of the plug was hot, the other was cold.
Thanks lot for the video I have same multimeter idont know how to use it
Excellent. Thanks
These things should be sold WITH line splitters.
But you'll often be using this to monitor power inside a consumer unit/distribution board where there's no need to 'split the lines', it's just people wanting to use these in-line with plugs that have the issue and we have commercial inline plug-in monitors available for sale already which are safer for general users.
Very good useful!!
