Measuring Capacitance
Measuring tips:
– For measuring capacitances
greater than 10,000
μ
F,
discharge the capacitor and
manually select a suitable
measurement range. This
will speed up measuring
time in order to obtain the
correct capacitance value.
– Ensure the polarity is correct
when measuring polarized
capacitors.
– For measuring small
capacitances, press
with the test leads open to
subtract the residual
capacitance of the
multimeter and leads.
CAUTION
Disconnect any circuit power and discharge all high-voltage capacitors
before measuring capacitance to prevent possible damage to the multimeter
or the device under test. To confirm that the capacitors have been
discharged, use the DC voltage measurement function.
