I got pulled into a Receiving Inspection problem. Our test instrument, an
old HP 4192A impedance meter, and a newer Instek 6020 tell us that our X5R
capacitors are out of spec.
A 100uF, 10%, 6.3V capacitor measures between 25% and 30% below the nominal
value.  The instruments have Kelvin probes and are zero calibrated at
frequrency, 120Hz the test waveform is 500mV rms.
Does anyone have any advise?
