Measuring Capacitance WCaution To avoid possible damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the dc voltage function to confirm that the capacitor is discharged. The Meter's capacitance ranges are 10.00 nF, 100.0 nF, 1.000 µF, 10.00 µF, 100.0 µF, and 9999 µF. To measure capacitance, set up the Meter as shown in Figure 6. To improve the accuracy of measurements less than 1000 nF, use the relative (REL) mode to subtract the residual capacitance of the Meter and leads. Note If too much electrical charge is present on the capacitor being tested, the display shows "diSC".
