    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

    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?

    • @totalcircuit
      @totalcircuit  2 місяці тому

      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.

    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...

    • @totalcircuit
      @totalcircuit  9 місяців тому

      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..

    • @totalcircuit
      @totalcircuit  10 місяців тому

      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 👍

    • @totalcircuit
      @totalcircuit  10 місяців тому

      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

      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.
