    I have the same Micronta DMM as you. Check the middle of the warning label on the back. There should be a circular soft spot in the middle, if yours is like mine. This is where the piezo speaker sound is supposed to come out. I guess the legal department doesn’t care about engineering. If you cut out the label above that hole your beeper will be 5x as loud.

    That was beautifully explained. I have a much better understanding on fft.
    I would love an explanation on IIR and FIR filters which is another niggling problem for me. Best rgds Andre (South Africa)

      Thank you!
      Regarding IIR and FIR filters ... you are not the only one. To be honest, I know absolutely nothing about them. Definitely out of my wheelhouse. This will be the first suggestion that I haven't happily jumped on with enthusiasm.

    Another very useful video Ralph. Another useful trick is to create an expanded scale voltmeter. For example, taking a 5 volt full scale movement and adding an external zener makes a useful 10 to 15 volt meter. If you have a meter with a scale specific to some odd ball function, you can make custom meter scales with a program called Meter Basic. There is a freeware version for simple single scale meters and a paid version that allows you to create multiple scales.

    Hi, i might be missing a video or something, but how do i know if i have an amm or voltmeter ? awesome content btw, thanks a lot.

      That, my friend, is a very good question! I did think about this while in preparation for this video, but didn't pursue the thought all the way to the final video. I have been noodling on the simplest way to do this all morning. The answer is very simple, but not easily described in the text of this reply. Sooooooooo, your question has sparked an unplanned, unscheduled video to answer it. I am absolutely sure that others are asking the same question in their mind. Let's see how fast I can throw something together. Thank you for your question! :-)

    Thank you for your video. I was getting so frustated that i could not find any information on google on how to calculate the internal resistance of ammeters i have at home. Finally i came across your video, Thank you for your well explained steps to calculate Internal resistance.

      Your experience has been my experience when it comes to a whole host of topics. This is what motivated me to create this channel. I am so glad to hear that it is meeting a need. :-)
