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.

@kamaldeepkumar5281 2 года назад

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..

Good idea , but in my module pin no.10 is the adc input.

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.

@FreeCircuitLab Год назад

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

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 Год назад

Add a trimmer as My diagram

@SAI_LINGESH Год назад

@@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?
