Capacitance Measurement

(Figure 8)
To avoid 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
The Meter's capacitance ranges are: 4 nF, 40 nF, 400 nF, 4
µF, 40 µF, and 200 µF.
To measure capacitance, connect the Meter as follows:
1. Insert the red test lead into the
the black test lead into the COM terminal.
2. Set the rotary switch to
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
Note:
• For testing the capacitor with polarity, connect the red clip
to anode & black clip to cathode instead of test leads as
mentioned above.
• To minimize the effect of
capacitance stored in the test
leads, the test lead should be
as short as possible. To measure
a small value of capacitor, use
REL mode to remove the test
leads capacitance. Remaining
voltage, insulated impedance,
& dielectric absorption from
the capacitor may cause the
measurement error.
• It takes a longer time when
testing a high capacitor value.
The testing time is around 30
seconds in 200 F range.
• The LCD displays OL indicating
the tested capacitor is shorted
or it exceeds the maximum range.
• When capacitance measurement has been completed,
disconnect the connection between the testing leads and the
circuit under test and remove the testing leads away from
the input terminals of the Meter.
