Hi,
I was trying to measure capacitor to ground for the pins of of my our product. I have 10 output pins with 220nF installed on board.
I used an high end Fluke handheld meter, and then tried to use a bench LCR meter. My all the pins shows the capacitance between 250nF to 400nF, which looks good.
My few pins measures cap around 2uF to 4uF. They consistently measures the same. I tried with different multimters.
I tried doing an electrical measurement by creating a low pass filter on those pins and apply a pulse voltage via 10k series resistor. My calculation based on measurement was showing 400nF.
I am not sure, why meter measurement reading looks so different.
I am putting it in this forum if anyone had similar experience.
Thanks in advance.
