    I built the poptronics esr meter with a FAR circuit board. when i check a
    regular cap it works as it should but when i check a electolitic it
    generates about 5 to 10 % more voltage at the meter than when the probes
    are touched and the meter is zeroed out. I have checked all componet
    location & polarity 3 times and the voltages are good checked with meter &
    O scope. any ideas?

    incorporated those corrections into your meter?
