    This' a definite must (HV probe)

    Just recently I went to an "expedition" to a local electronics surplus store and suffice to say after hours of rummaging I think I scored a prize (cost me $10) - a 30KV HV probe.



    After trying the probe I do not know how I lived without it and I am wholeheartedly recommending everyone messing with HV DC gets one. This is such a simple yet effective tool that removes guesswork from the equation...

    You could probably build one as well, just need an analog panel meter and a ultra high resistance, mine appears to be 600Mohm. But why build when you might be able to source one cheap and neatly packaged like this...
    Are the ravings of a lunatic signs of a genius?

    Good deal!
    Fluke sells the 40kv unit for around $50-$100 and cheaper on Ebay. Its double that price where I live, so likely end up building one.

    enjoy!

      Don't mean to sound like a noob, but what do you do with it?

        If you try measure the output of lets say an ignition coil (HV) while its outputting voltages around 2000 volts+ and with your regular multimeter, the high voltage ends up frying the meter, usually leaving it in a semi working state.

        The HV probe connects to your meter and allows you to take HV readings without putting your meter at risk.

          Gotcha,

          After I typed the last message I realised what I was doing, (having a brain fart) and so I just googled it. I'm going to have to get one as I will very shortly be doing some HV experiments myself. The generator I bought has no meter on it, so it will come in handy.
