4.3.6. Capacitance
measurement
CAUTION
Before taking capacitance measurement in circuit remove power from the
circuit being tested and discharge all capacitors. Connect the test capacitor
to the inputs respecting the polarity connections when required.
Fig. 7: Using the instrument for capacitance measurement
1. Switch on
CAP
2. Pressing the
MODE
key until the “nF” symbol is shown at display to meaning the
capacitance measurement
3. Insert the test leads into the jacks, the red plug into
V
Hz%
CAP
jack and black
plug into
COM
jack (see Fig. 7)
4. Press the
REL
key before start the measurement
5. Connect the red and black test clamps to the capacitor terminals respecting if
necessary the proper polarities. The capacitance value is shown on display
6. If the message "
O
.
L
" is displayed the higher range is reached
7. For HOLD function and Relative measurement please refer to § 4.2
