4.3.7. Capacitance measurement
CAUTION
Before taking capacitance measurements in circuit remove power from the
circuit being tested and discharge all capacitors. Due to internal delay time,
bargraph it’s no operative in capacitance measurement.
Fig. 8: Using the instrument for Capacitance measurement
1. Selecting the position
2. Insert the test leads into the jacks, the red plug into V Hz
A jack and black
plug into COM jack
3. Connect the red and black test clamps to the capacitor terminals respecting if
necessary the proper polarities (see Fig. 8). The capacitance value is shown on
display
4. Pressing the R/SEL key to select the correct range or using the Autorange feature
(see § 4.2). If the capacitance value under test is unknown, select the highest range.
5. If the message " O.L " is displayed the maximum readable value is reached.
6. For HOLD function, Minimum and Maximum value measurement and Relative
measure please refer to § 4.2.
