Measuring Capacitance
To avoid possible damage to the multimeter or to the equipment under test,
CAUTION
disconnect circuit power and discharge all high-voltage capacitors before
measuring capacitance. Use the DC voltage function to confirm that the
capacitor is fully discharged.
Set up your multimeter to measure capacitance as shown in Figure 2-16. Probe
the test points and read the display.
