Very informative and thanks a lot for such a deep thorough study and experimental, which no one else ever made. However, I must appreciate and looking forward to seeing further. Keep it up!!!!
Very very nice video, bhut se or bhi multimeter ke videos hai but app ka video sb se jiyada knowledge details hai .eassa ho sakta ke voltage napne ki alg and current ki alg video thora slow speed se dal do .bhut hi nice lgi app video sir lots of tnx for good efforts
Sir app ka bhut mehaerbani hogi agr ek resistance napne wala and isi meter ko counineouty check krne wala meter bna kr circuit ka video upload ke de please
I have DM9205A. By mistake It's got inserted the probes to power source 230 volts while selector switch was at resistance point 2 k ohms. Got busted one resistor, but now no display or buzzer sound at all. What would be the remedy for it?
Excellent concept sir superb... If i seen this video before,i may save my two multimeter and i use them as you told like voltmeter or ammeter. Sir in DT9205 , hfe and 200mv in between this two options, one traingle(∆)symbol is there what is the use of that option sir...
The symbol that comes in the middle of Hef 200 mv works just like NCV, no multimeter has to be connected in it, it will give LED indication of voltage from a distance and a beep sound will be heard in the buzzer. But it is not used in this multimeter And there's no way it's going to work you ignore it Thank you
Very nice... Actually I already made ur 7107 amp meter.. Its working properly but one problem is after the decimal point the value is continue fluctuating like I measure 5.18 amps... But its showing 5.23, 5.18, 5.08, 5.15... Any solution for stable reading...?? Thank you..
Reason for fluctuations in decimal point (1) Not having proper filter in meter supply (2) Install a 100 nano Farad (104) capacitor in ICL 7107 IC. Connect both the pins of the capacitor to 30 and 31 pins of ICL 7107 IC. This can be a solution. Or test the current from the battery and see if it is correct. If it appears correct, there may be a fault in the power supply providing current
thank you for the great work, i have a question about dt830d,on the buzzer mode , when i contact the two probes, the buzzer's sound come too late, about 2 secondes, not immediately. plz answer my question, and thank you very much 👍
In DT830 multimeter the buzzer rings for some time. You are right. To fix this problem, the circuit diagram is in the description in the video. In the circuit diagram, a 100 nano diode capacitor is installed on pin number 39. That capacitor is connected to the common. The size of the capacitor can be SMD. Remove this capacitor from here and the problem will be solved. Or should I make a video on this and tell me please comment. thank you for watching this video have a nice day
My another DT 830D display on & slowly vanish . This fault came when meter test ac point but arrow was maybe dc voltage point . What to do? How is it recover?
Have you tested the AC voltage across your resistance point, this could be the LCD display IC of the multimeter being damaged, you can get another multimeter. Thanks
meter DT9205A gas lighter k voltage check krtay huay, jo k meray khyaal mai high voltage thay, khraab ho gya hay aur ab screen pr hr position pr sirf 1 likha hua aa rha hay. Kia ye repairable hay. Please aap koi video bna dain.
Ges lighter mein high voltage hota hai isliye multimeter ki men ic kharab ho sakti hai iske liye aap circuit mein bataenge anusar sabhi pin Ko aapas mein common ke sath mein jod do 000 Ho jaega To multimeter ki IC sahi hai anyatha kharab

Sir Aap Ne Is Par Full research Kiya Hai 👌
बहुत बहुत धन्यवाद गुरूजी 🙏🙏🙏🙏🙏

Good one..
Make a video regarding old cfl smps for dual positive and negative 12v output..
Okay

Thank you.
Sir ye yellow wala multimeter dead condition me hai water damage kya thik ho sakta h?
Multimeter ko Safai karke. Chalu kijiye chalu nahin hota hai to new khareed lijiye thanks

Due to high voltage, the IC of the multimeter may get damaged. The display does not appear on the multimeter. You will have to buy a new multimeter.

Thank you for your reply sir.
Buzzer mode me check karte samaya capacitor ka voltege ne multimeter ko dead kardiya banega wa naya lena hoga
Multimeter dusra Lena hoga

Sir unity DT 9205A multimeter main continuity per beep sound a rahi hai kaise problem solve Karen please reply de
Multimeter mein select switch ki tric kharab ho sakte hain ya koi resistance jali hui ho sakti hai
Mera multimeter ka ghumane wala knob Tut gya hai uska repair ho sakta hai kya
Multimeter ki knob Tut gai hai uske liye aap fevikwik se chipka sakte ho anyatha aapko dusra multimeter hi Lena hoga
