That background tune fading in and out just blew my mind. What genius thought it would be a great addition to the already mismatched audio of this video?
seems mismatched because it's an AI translation dub. the person is originally speaking some other language. most videos in this channel are not english.
Probably missed the point that should be made that per the instruction manual "Make sure the conductor to be tested is placed at the center of the transformer jaw, otherwise it will cause +1.0% deviation based on the stated accuracy"
Thanks for this video. I actually want to know how much amperes an electric engine consumes in a three phase system. Do you need to measure all three phases separately and sum the values up to get the total consumption? Or should you still divide by 3 to get the average? Keep up the good vids ;)
The rated current of the induction motor will be In = 1000Pn / √3 • (η • U • cosφ). Pn is the power of the electric motor, measured in kW. U is the voltage at which the motor is running. η is the efficiency, usually 0.9
Thank you for your clear explanation of clamp meters. I am just starting with them, so this helped get the gist of them, but I have to say that it is annoying that when selecting which clamp meters is best for you, you encounter these annoying differences in accuracy. In your video here these 2 meters of the same brand (albeit different design) end up with 2 different measurements of the water cooker's AC current, namely 7.61 amp and 7.92 amp. That is so annoying. Which one is then the most accurate and why is that ? I am at the moment having several 30 to 90 dollars models from Amazon to compare and select and most of them give non comparable readings on something basic as this AC current. I would almosts say "I hate them all !" ;-p
Unfortunately, sometimes it is difficult to say which device will be more accurate, especially considering the fact that at different times and under different conditions they will always show different values. There are many factors influencing this. One way to test this is to measure something nominal and known and compare the value to the nominal. Thanks for the detailed comment!
@@ToolBoomVideo Thank you for replying ! I am somewhat intense when looking into something I want or need, but today I got lucky in finding what seems to be the right clampmeter for me. A Meterk MK06 that is ridiculously cheap, but measures DC current over the clamp up to 400 amps and from the looks of it, is accurate enough. I decided to try my luck overnight and today it arrived and in all it's "el cheapo" simplicity I am just gobsmacked so to speak.
Is there a way with this or another tool to measure the voltage wirelessly? I'm trying to find a break in a line and was hoping to use some kind of wireless device to detect where the break in the line is, as the break is under the insulation, so not visible. Thanks
in AC when clamping the entire cable (both conductors) it would read a Zero, as the alternativing current is out of phase: but my question is can it read the DC current when both DC conductors run through it ? you were so close to showing this in your demo...
I clamped the jaws directly onto the insulated power cable running 220 volts to a domestic bar heater pulling 800 watts and got a reading of 0.7 amps on the 20 amp setting. Is this just a nonsense reading and what is causing the reading?
What do you have the power supply unit connected to? That would be helpful to know, so others can do a similar accuracy/verification test of their clamp meter.
I bought a clamp multimeter UNI-T UT204+ . But I did not understand the REL/ZERO button function. I looked around internet but not able to find how to use that button. Can you please tell the functions of that button. Thank you in advance. Best regards.
Hello! Typically, most clamp meter models have a voltage measurement function. That is, you can measure the voltage across the battery terminals. For example, such a device: toolboom.com/en/834634-digital-clamp-meter-uni-t-ut204a/ But to check the capacity, you will need other devices - battery analyzers.
Hi! Great video. If my multimeter says 00.00 every time even though electricity is clearly running through the wire, what does this mean? Is it too high or too low to read? Thanks.
Are you lip syncing or is your video lagging? Either way, it's something to look into fixing. Channel is great otherwise! Loved your review on the UNI-T139C
The Creatures HM Thank you for your attention. This is not a problem of synchronization of audio and video. The fact that we are an international online store, and translate our videos in different languages.
Cool - what can i search for to find AC wires that are separated like that already? or must i make my own.. seems dangerous to risk a DIY at my novice level
Hello! If you are a beginner, you should not do this. And the presence of alternating current can be checked with the help of current clamps, which have a mode of measuring alternating current
Here's a hypothetical ... I have two feed lines (wires), both are power side (not common). Neither power wire is energized at one time. I would like to be able to measure current without having to clamp and re-clamp. Can I clamp both lines, and still read current (amps) on the energized wire, with no current in the other wire? Why? I want to have a helper watching the meter, while I energize and de-energize in a remote location.
Hello! You can choose model UNI-T UT206A - only for АС up to 1000A, or UNI-T UT207A - for АС and DC up to 1000A. toolboom.com/en/822365-digital-clamp-meter-uni-t-ut206a/ toolboom.com/en/digital-clamp-meter-uni-t-ut207a/
Just bought a one dollar clamp meter brand new. It claims to be able to measure up to 300 volts ac and dc and up to 400 amps. When I set it to the specific modes I want to test out. It wont read any voltage or amps on those test. Its a chepo hyper tough from walmart. Not sure why it wont do any readings. Or is it just to cheap. How cheap can you go without sacrificing safety and accuracy?
if you don't get 0 net current in live and neutral this is likely due to an electrician wiring error in your house, as some current is not returning and going along another circuit (another neutral or ground, potentially even riding out on a water pipe); this is important as you are generating a net magnetic field in your house due to unbalanced net current, creating a health hazard as health effects are reported above 1 milligauss magnetic field, especially an AC field generated from AC currents
For current measuring, are Hall sensor meters less accurate than current transformers, or about the same? Also, does it matter where, within the circle of the clamp, the conductor is? Will the meter be more accurate if the conductor is placed exactly within the center of the clamp?
@@ToolBoomVideo Can you kindly make a 10 sec clip to show this concept. I believe neutral wire don't carry current (under normal conditions and single phase system). But this concept violates the principle of using a neutral wire in the first place so I am really confused.
why when I use the ut203 on DC, I can get two different readings depending on the direction of the + on the meter. If it is facing the battery positive or facing the battery negative it reads differently
that due to the one way flow of a dc current. assuming that your getting a positive reading one way and negative reading when you turn the clamp the other direction.
I have this multi meter and have measured just one wire off of a 3 phase generator but only get between .013 or .054 amps from the wires. In any wire in my home after getting to just the hot wire or neutral I read .008 amps as the highest going to a 1kwh electric stove top. So I can see current just not anywhere close to accurate. Is this common? ( I started high and have gone to the lowest setting of 2/20A)
Hello! Please measure again. Measure only one wire (active or neutral). Set the current measurement mode to "AC". Be sure to connect the load to the mains - any household appliances, electric kettle or something else. We are confident that the measurements will be correct.
Me idiot was trying measure voltage, voltage not current, clamping a fully isolated lead, after getting weird readings or nothing at all started googling how it's used, here I am, lol.
I am not an English speaking guy..Unlike other You tube videos, yours have text or printed explanations. That really helps a lot.. Your New subscriber..
If the meter shows zero amps on a single wire conductor while using the amp clamps, am I to safely assume that the electrical circuit is off or switched off?
Appreciate the video. If I wanted to measure a house's main panel TOTAL amperage draw, would it be just the reading of 1 hot feed wire or do I add the value of both feed wires together (for standard meter service with two 120V feeds)?
Hello. For each task, you need to choose a specific device. If it is a question of measuring high current, then it is necessary to measure using current clamps. The multimeter, in turn, usually has more advanced functionality, but the current measures within 10-20 A
Hello! Thank you for your question! In theory - yes, but the device will show indicators only from the clamp (measurement of current) or from test leads, so the measurement should be done separately.
nice and educating video how can we use this clamp meter to measure direct current from solar panel....? can we use probes to measure current like we do to measure voltage.

Hi! Great video. If my multimeter says 00.00 every time even though electricity is clearly running through the wire, what does this mean? Is it too high or too low to read? Thanks.
Hello! Please measure AC only on 1 core wire (as shown in the video, 2.20 - ruclips.net/video/Bc_EQea0mKY/видео.html ).
Can they be used to find an open circuit as in a broken wire?
Thanks mate

in fact learn about gaussmeter testing (walking around your house with a gaussmeter) to look for correctly wired circuits
You didnt explaint the last two choise
For current measuring, are Hall sensor meters less accurate than current transformers, or about the same? Also, does it matter where, within the circle of the clamp, the conductor is? Will the meter be more accurate if the conductor is placed exactly within the center of the clamp?
Hello! In terms of accuracy, both options will be approximately the same. In the center, the readings will be a little more accurate.
Hey what happens if you use the clamp meter on the NEUTRAL wire while appliance is on?
If you test the neutral wire with a clamp, you will see the value of the current in the circuit. (Not to be confused with ground wire)
@@ToolBoomVideo Can you kindly make a 10 sec clip to show this concept. I believe neutral wire don't carry current (under normal conditions and single phase system). But this concept violates the principle of using a neutral wire in the first place so I am really confused.
This is like a bad Japanese movie where the language spoken does not match up with lip/mouth movements.
Hello. Thank you for your feedback! Initially, we shoot one video, and only then we translate into several languages. We try to avoid this problem. :)
So what is the best DC clamp meter?
Hello! It all depends on the accuracy class, required parameters and number of functions. Buy the model that will meet your requirements.
why when I use the ut203 on DC, I can get two different readings depending on the direction of the + on the meter. If it is facing the battery positive or facing the battery negative it reads differently
that due to the one way flow of a dc current. assuming that your getting a positive reading one way and negative reading when you turn the clamp the other direction.

So the "clamps" on the meters can only measure amperage? They cannot measure voltage or resistance without using the + or - probes??
Hello. Yes, clamps usually measure only amperage, and with the help of probes, all other values.
So if I'm welding with D.C current I need one that reads ac/dc?
If the meter shows zero amps on a single wire conductor while using the amp clamps, am I to safely assume that the electrical circuit is off or switched off?
No, this does not mean, since the load on each phase is not distributed symmetrically or evenly.

2:23 ..and this is the thing I forgot again - was wondering why the clamp didn't work, thanks!
would there be any reason someone would get a multimeter over a clamp meter since a clamp meter can measure so many more amps?
Hello. For each task, you need to choose a specific device. If it is a question of measuring high current, then it is necessary to measure using current clamps. The multimeter, in turn, usually has more advanced functionality, but the current measures within 10-20 A
I notice the leads are not installed ..can I use the clamp with my leads still attached to the meter?

how can we use this clamp meter to measure direct current from solar panel....?

Solar Panels output DC not AC ~ so you would need to have a meter that can read DC
The CE on these meters stands for "China Export" instead of meaning that it conforms to European Standards. Tricky Tricky.
