2 Making Measurements
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.
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.
1 To measure capacitance, position the rotary switch to
