I bought this 3 wire multi meter display from local electronics market, in my display’s back there is no tuning potentiometer. Is there anyway to calibrate the display? Or it’s a piece a waste ? Or I got scammed?
@@FreeCircuitLab Actually my meter shows less voltage than accurate voltage! If i add a potentiometer like you explained in this video, does it show accurate voltage?
I needed exactly this information. If it were in English it would be more useful. A translation would help very much. The diagrams are all that I understand. What language is this? Thank you.
Sir ek help chahiye 3 phase welding set hai tube mill ke liye ander ROOM me rkhe hai Lekin unki display Mill pr chahiye Taki Current km jyada kre to dikhta rhe Assa ho skta hai hai alg se display lg skta hai kya POT to alg se lga rkha hai
In order to measure high current just use pre-made shunt resistor of 0.1ohm and the amplify it using op-amp coz the resistance of wire change once they start heating and this meter has a drawback too it although they advertise it to measure from 0_100 it's actually range is 0.6(+or - 0.1)- 100 So in order to measure low current just by pass the amplifier this is what I came up with when I was trying to make a usb voltage and current tester..
Mere pas jo digital volt-Amp. Meter hai, usme maximum 9.99 Amp tak nap sakte hai. Mujhe 20Amp.tak napna hai. Kya shunt use karu. Kaise, kis value ka. reading kaise milagi. Es bare me ho sake to ek vedio banave. Pl. Mujhe salution de. Thanks.
I request you in few videos but you don't answered me 🥺🥺🥺🥺🥺🥺🥺🥺🥺🥺🥺🥺 Please sir make a amplifier using 2030 ic using 12 v battery 🔋 please sir make it 🥺🥺🥺🥺🥺🥺🥺🥺
Thanks. Could you please send me your contact number? Yeh aapne kaha se kharida? Mai bhi ek project me use kar raha hu kintu uske peeche chip nahi dikhti.
*We have SuperThanks now,↑↑*
You can value the knowledge you just got, and help more such videos coming
Thanks from Pakistan. The video is the best wrt engineering side of things and not going to neety-greety details. Keep up the good work.
Onek kichu sikhlam dada ai video ta theke
Thank you for this knowledge 😊
Thank you so much for making this wonderful and informative video.
Thankyou for making video .Bhit jyada helpful video hai . I am student of E&TC
knowledge is most powerfull tool. Good Information. Video.
bhai tum kamaal ho.. sb kuch btate ho ...
बहुत बढ़िया 👍
GOOD TICHING KARTE HO AP ,🌹😆👌👌👌👌
Very useful information and waiting for your next video.
Thank you very much. Good night 🙏
Thank you so much for making this wonderful video.
Bahut informative video hai
Sir next video me isko ek ammeter banakar dekhow .thaks for giving eletronics knowledge.
very good thanks bhi jai hind
Awesome explanation.
Nice!
I have many of 7 segment display, can make volt amp meter homemade?
Badhiya.

@@FreeCircuitLab I will try
Video bhut mast tha
i am waiting. for youre next video ..
V good explanation.
Ooooooooosame Very Nise vai 👌

This is Hindi(India), as per your request, I will soon translate it on my english channel "Free Circuit Lab ENG"
Very good....

Sir ek help chahiye
3 phase welding set hai tube mill ke liye ander ROOM me rkhe hai
Lekin unki display Mill pr chahiye Taki Current km jyada kre to dikhta rhe Assa ho skta hai hai alg se display lg skta hai kya
POT to alg se lga rkha hai
Ho jayega.
Very nice video ❤️
Nice idea 👍👍
great!! Thanks.

very nice
How to know the values of resistors to use ?

Sir when will be your digital clock video published . please upload as soon as possible i am wating egarously.
Good idea , but in my module pin no.10 is the adc input.
