Awesome video, and thanks for the info. I just started racing RC off road, and this is a great way to see if your motor timing is set properly. I was going to buy an rc watt meter, but I already had a multimeter, so this video saved me $50. Thanks! ps for those that race, a 17.5t racing motor should draw around 3.5A (max) with pinion removed, at full throttle. If its higher than that, you've timed it too aggressively.
The same way as with a digital, just make sure you have the positive lead connected to the 10A or red AMP terminal on the multimeter, otherwise you can bend your dial needle with a negative reading.
coil of the electron, its magnetic field pushed the electron of the iron. for this reason, in iron (+) charge is generated. the attraction force of the coil is the electron and iron. and the force is in direction of electron current. the resistance of coil is less.
I just fried the amp portion on my multimeter. I had touched the positive to the positive of my solar charger input and the negative to the negative of the solar charger input. The charger had connected the solar inputs to the battery inputs so I had created a circuit I guess. I can't believe I didn't think of that happening. Oh well. Thanks for the video. I now know that when measuring Amps, I have to "intercept" the current so it is not read like voltage.
Hi, I have to test the actual max amp of a 110AC to 12DV transformer for my project. (can't believe what the label says) Which tool would you use for such test? Any easier alternative to the drill? Many thanks!
can you tel where did you get that grey plastic connector that you plug the two wires and that kind a yellow one also, a link or something please will appreciated
let's say if I have to measure amps from a 6 v motorbike battery so must I connect the battery to a motor first and then measure apms or I can directly measure amps from the battery alone ?
On a digital meter, all it would do is yield a negative number as all the Amp mode does is measure the voltage drop across a shunt resistor (kind of). Consider AC where the current is cycling positive negative positive negative. The multimeter would have to be able to handle the current going both ways. In short, no, it shouldn't hurt your multimeter.
This is probably a NiCd battery and this trick will work on these type of batteries. Mine drill is a 20v one Li-Ion, when i try to connect it to the multimeter and test the amps it can't start, i check the voltage and it's around 15,57V... Amps are only 10 miliamps. There is some kind of a connection that needs to make contact to let the full voltage but i dunno how...
Thank you sir. I've fried cheap meters trying to read amps draw. My meters say 10 amps but I'm not confident that they can handle that. In the past I tried it and blew the internal fuse but still fried the meter....don't know why they design stuff that has a fuse for protection but in actuality the fuse doesn't do the job and the instrument get fried anyway ????
Hi, can you help me with something? I have a positive and negative wire going to the back of my van. This wire was used to power a wheelchair lift. I gave the lift away and now I have the cut wires. How can I figure out how many amps it can provide? I know hoe to test volts but how do I test those two wires, positive and negative, to know how many watts are coming out? Thank you.
+Josh3292 No, I don't know sorry. I was just told that it should go in the negative side. My electrical knowledge is limited, but someone else might know. Thanks for the comment
The negative terminal is where the electrons flow from, and the but it shouldn't make any difference. The current should be the same on both terminals.
cool, but i need to know how i can measure the milli/amps in a battery.....without anything connected. how do i do that? i have multimeters.....i have a certain 3.7v battery and it seems extremely powerful compared to other 3.7v batteries i have going by the same thing being connected, nothing is written on it amperage wise....cheers.
@@ultimatehandyman no problem cheers for the reply, yes strange isnt it, i was experimenting yesterday, set my meter to milliamps...connected it to a 12v solar panel and could read the millamps no problem.....unhooked it, connected it to several batteries...and nothing....strange...i thougyt measuring a batteries amperage would have been uber simpke, but apparently not... hmmmmmmm...
oh ok well thats true, thanks i was just looking to see if i can apply this to my robotic projects as im looking to see how i can read torque from any dc motor by using the multimeter
DUDE! CAN YOU PLEASE HELP ME OUT, I HAVE A CLAMP METER MODEL DT266 AND I WANT TO TEST AMPS ON AC, IF IT STILL WORK OR NOT, MY CURRENT READING IT STAYS 0.. PLEASE HELP ME!!!
I mean to say that how I can ascertain that a battery is good enough to use for how much time. Would voltage readings on a multimeter is only way or any other way also...
the magnetic field is due to electron (the effect of the magnetic field and the electron velocity). EXPLAIN- wire is the electron collision of the magnetic field, the magnetic field of electron of wire or sensors of multimeter. effect of magnetic field and velocity of electron, take care. wire the electron, its magnetic field are pushed in the direction in which the electron of the multimeter to the wire or sensors. according to the current generated in multimeter wire or sensors, and according to the current mesure. change the direction of the wire. multimeter to measure the change in current. NEXT MULTIMETER - same theory apply. but, for half rotation, and it will focus on the structure of the coil of motor without load condition- time spent half the time = t with load condition- time spent half the time = t+dt works as a resistance coil. but, for dt time. coil resistance is reduce change on the iron charge. resistance to change in the type of coil.
and (+) charge arising in iron, is to reduce the number of electron in it. the cause of the electron's magnetic field coil is pushed by the low electron. the reason is reduced resistance of coil.
i didn't say you were measuring amps in the wrong way. You were spending too much time showing what is the wrong way before you actually showed the correct way
he was right to show the wrong way that people are confused about ac and dc amps ...... i m an engineer and people literally dont know about which clamp meter to buy ..... as ac clamp meter is way cheaper than dc amp meter, they always ask the same query repeatedly
Very simple and very understandable. Many thanks for making and sharing this. Greetings from Turkiye!!!
thank you. The only person who addresses the question can you test from the negative side and the positive side. brilliant. good job.
You are welcome.
Thanks for the comment
Finally a video that does exactly what the title says and in a
clear concise way, thank you.

I like those quick connectors you got, great video!
Awesome video, in my opinion a must see for all A/V technicians. Thanks a lot!
thank goodness for a simple yet cautious video on this topic. thank you for your video.

Thanks for the comment 👍
Those Wago 222 series are lovely.
Yes, they are great ;-)
Thanks for the comment
that was plain and simple but very helpful thank you very much
I’m glad you found the video useful
Thanks for the comment 👍
very good demonstration for teaching in a class setting
Thanks for the comment ;-)
Very nice. And in focus no less!
This answered my question. Funny, the instruction booklet that came with my tester didn't explain it this simple. Go to YT!
I'm glad the video helped
Thanks for the comment 👍
DeWalt, good choice. Looking to get one of their corded drills.
Go Makita far superior and their batteries have protective circuitry to prevent over discharge !
simple and informative .. i like that kind of videos

Great video. So what was the max amps the drill pulled under load. Saw it get close to 19amps and your metre is rated to 20amps max.?
Damien Kubik
Thanks, yes I think the maximum it pulled was about 19amps.
Thanks for the comment
I pulled a 1500 in-lb. cordless impact driver apart. The trigger speed control is rated at 20 amps.
I just fried the amp portion on my multimeter. I had touched the positive to the positive of my solar charger input and the negative to the negative of the solar charger input. The charger had connected the solar inputs to the battery inputs so I had created a circuit I guess. I can't believe I didn't think of that happening. Oh well. Thanks for the video.

You can buy a probe which handles higher current you just have to convert the reading by moving the decimal place over a certain amount. :)
THANKS FOR YOUR HELP.
Awesome, i need to make some clips for my meter instead of the probes.
Thanks, very helpful.

Thanks for sharing...
Thank you!
Have you tested the brushless drill, does it draw similar current? Thanks.
No, I only did this to demonstrate how to measure amps.
Thanks for the comment 👍
@ultimatehandyman - Can we make the same connection using a Variable Speed electric Drill ( 120 Volts ) ????
I was thinking burnley or rochdale, but west midlands is way out. Brummies don't say load like "lord". Darwen's a great place, amazing countryside.
Thank you very good info
Thanks for the comment
can you tel where did you get that grey plastic connector that you plug the two wires and that kind a yellow one also, a link or something please will appreciated
I believe it was these-

Yes, the connectors were very good to use...
thank you for the info..........
What is the name of this grey connector attached to the negative wire?
let's say if I have to measure amps from a 6 v motorbike battery so must I connect the battery to a motor first and then measure apms or I can directly measure amps from the battery alone ?

That has not happened to me - yet.
The fuse should always protect the instrument, that is what it is there for!

Might be best asking an auto electrician 😉
Hey thanks !
+Ultimate Handyman
So does it matter which wire you should choose for amps rating? Becauce I see different wire showed different ratings.
+Josh3292
You would normally measure the negative side -
Thanks for the comment
Thanks, can you explain in details why?
+Josh3292
No, I don't know sorry. I was just told that it should go in the negative side.
My electrical knowledge is limited, but someone else might know.

Lancashire or Yorkshire?
nice, thank you
Thanks....
very clear video. I have been looking for the type of terminal block with the orange leavers you are using you video. any informaion would be great
can i measure my car alternator amps with my 20amp multimeter. if yes please tell me how
Was this drill set on highest torque?
Not sure, it was filmed many years ago.
Thanks for the comment
What is the capacity of your Battery?
Then how to measure that.,other than buying an expensive ampmeter. could you please explain

do you have a video on testing DC brushed motor amps? using a multimeter
Frank Lopez
This is a DC brushed motor in the drill I'm using.
I'm afraid I don't have any more, sorry!
oh ok well thats true, thanks i was just looking to see if i can apply this to my robotic projects as im looking to see how i can read torque from any dc motor by using the multimeter
Frank Lopez
That sounds like an interesting project.
Best of luck with it ;-)

How Do i know if Fuse inside the multimeter is busted ? any shortcut ?
+asad
You need something to test it with really. But if the meter is not working and the batteries are good the chances are that it's the fuse.
How to check Current Storing Capacity in terms of mAh of any battery....Please explain...
Sorry, I do not know as it's something I have never done before.
I mean to say that how I can ascertain that a battery is good enough to use for how much time. Would voltage readings on a multimeter is only way or any other way also...
@7divad37 I would rather it be done using a circuit board than that drill.
I meant the tool to draw power from the transformer. I have a multi-meter already.
You good 😊
Thanks for the comment 👍
need to know how to with a non digital multimeter

How do we calc amps per hour?
+liveuk Not sure, sorry. I'm sure if you Google it you will get plenty of results.Thanks for the comment
+Ultimate Handyman Thanks I get to many results on the google, Looks like our Meters are showing amps per hour as a reading yet it's instant?
+liveuk czcams.com/video/cxkVxi9P0EA/video.html
If you do not put positive in the right direction than you would not get the right amount of amps
Good thx more amp the drill the more torque the drill has ..
Cable is heating
Prefuct!
let it run,, got no charger,,ok I see..
you sound like karl pilkington from An Idiot Abroad.
TheEgg185 LOL, I was watching that last night ;-)
i don't understand why is he demonstrating the wrong way to measure the amp in the first place
+victor amechazurra What do you mean by I'm measuring amps in the wrong way?Please explain?
i didn't say you were measuring amps in the wrong way. You were spending too much time showing what is the wrong way before you actually showed the correct way
in case someone looking for an easy way to measure amps,
he just saved him money and time by showing that Clamp works for AC.
he was right to show the wrong way that people are confused about ac and dc amps ...... i m an engineer and people literally dont know about which clamp meter to buy ..... as ac clamp meter is way cheaper than dc amp meter, they always ask the same query repeatedly
what sort of english is this?
talk less please
That unit t multimetre is really good mine has lasted over 5 years and still going
