ESR Meter

Posted on Feb 6, 2014

Take a good capacitor, around 100 or 1000 microfarads, and connect a small resistor, 10 or 5 ohms, in series with it. Connect to the meter and adjust that pot until the meter reads the resistance of that resistor. Repeat with other capacitors and resistors as a check on your calibration. Limitations:Capacitors smaller than about 10 mi

crofarads cannot be measured with ESR. Capacitance down to 10 picofarads may be measured, however devices with appreciable leakage cannot be measured at all for capacitance.
