I tried that several times after I had posted the video, I eventually had to adjust the "zero" trimmer on the A3 board to correct it. For its short comings it's still a very useful instrument. Thanks for watching!
I hear ya, power sensors can still fetch some high prices but I have been able to get them for $150-$200. The HP8481A sensor in the video cost me about $220.
@@CraigPetersen12f36b I don't have a meter yet for that very same reason, however there are cheap Chinese sensors for about $25.00, would be interested to see how they would compare to your HP counterpart? ~Jack, VEG
