I did something similar but I put the probes on "com" and "amp". My multimeters read max 10A and with that way amp reading was droped. I calculated the factor of ampdraw of a stable system with and without the shunt and then with the shunt I can check any system multiplying the reading with the known factor. BUT now I ll probably do it your way, more accurate. Thanks!
Clever trick! 👍 Using Schunts you can make a current meter for pretty much any range. If you are tight on budget, by this method you can save money from expensive DC current clamps. 💵💷💶
I didn't think it would measure so correctly but it surprised me. For higher currents you have to make a thicker shunt and just change them. Thank you Brother🙂🤝
The only issue with this is you will want a far bigger shunt for 200A since this shunt is going to heat up fairly decently at 200A and then your accuracy goes out the window. This will work in a pinch though in leu of a dedicated say 400-600A shunt meter
Agreed. Copper has a profound positive temperature coefficient which will cause your meter to read off calibration high as current through the wire warms it up. Precision ammeter shunts are fabricated from manganin alloy. A mixture of metals with a near zero resistive tempco. But yes, at levels much below 50 or so amps, your technique is 'gud nuf for guvment work'! Nice video.

Thank you🙂
Great topic, thanks 👍
danke, your video on upgrade the multimeter IS THE MOST COMPLETE one, GOOD WORK, ich bedanke mich + alles gute !!!
Vielen dank🙏🙂
@@ErCanEverything keine uhr sache, alles gute !!!
Good work 👍👍👍
Very nice
Good work
Thank you🙂
You didn't measure 200A. That shunt will not be able to support 200 Amp's.
can the rshunt made in this video be used on a digital volt ammeter,
Super!
👏👏👏🤙
Can also be made by measuring millivolts dropped over the shunt, that's the way I made mine.
👍👍👍
nos haría el favor y nos deja como se hace la formula para cortar la cantidad de longitud de cable de cobre le a gradecería el ejemplo de e video
need test for car battery 😅
Very nice brother....careful calculation
Thank you my Friend🙂🤝🤝🤝
Bom dia parabens
Thank you.
Have a nice day🙂
No es inseguro utilizar un multímetro para medir semejantes corrientes, si ya existen las pinzas amperimétricas.
wrong way: you made a coil!
When I calibrated it was a U-shaped wire.
If you like you can leave it that way and it won't be a coil anymore🤷♂️
you have to display your ignorance...i know it is your right...take some laxative and losen your brain cells
If you can't speak I can't watch.
