Measuring Electrolytic Capacitors with DMM
This during a repair. I did some measurements to show that a DMM is unfit to measure capacitance with the goal to know if it is bad. New Panasonic low ESR FM, 50V 22 uFLCR meter: 21,01uF, D=0,025 at 100 HzDatasheet: D new max 0,1At 100 kHz the impedance is |Z|=0,34 ohm, that is: Z=0,33ohm-j0,072, … Read more
