    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?

    The first Poptronics article was absolutely riddled with drafting
    errors. Later they brought out a lot of corrections. Have you
    incorporated those corrections into your meter?

    Please consider buying an EVB ESR meter. This piece of equipment is great. I
    don't know what is your purpose of checking ceramic or polyester caps
    because they almost never wear out. Regular ohm meter should be fine for
    those.
