Measuring Capacitance
Set up your multimeter to measure capacitance as shown in
Figure 2- 27. Probe the test points, and read the display.

CAUTION
To avoid possible damage to the multimeter 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 fully discharged.
NOTE
• The multimeter measures capacitance by charging the capacitor with a
known current for a known period of time, measuring the resulting
voltage, and then calculating the capacitance.
• is shown on the bottom left of the display when the capacitor is
charging, and is shown when the capacitor is discharging.
NOTE
To improve measurement accuracy of small value capacitors, press
with the test leads open to subtract the residual capacitance of the
multimeter and leads.
