6.7. Capacitance measurement
ATTENTION! Capacitors can store very high voltages. Before any measurement discharge the
Capacitor to be measured. For this purpose, put a resistance of 100 k over the capacitor terminals.
Avoid the contact or bare wiring (injury by electric shock!).
Measuring of charged capacitors may result in damage to the instrument.
1. Turn off power to the device under test and discharge all capacitors.
2. Discharge all voltage from the capacitor before measuring is capacitance value.
Note:
A safe way to discharge a capacitor is to connect a 100 k resistor across the two capacitor leads.
3. Set the rotary switch to the
4. Select the CAP-function by pressing MODE-button.
5. Plug the black and red test leads into the COM and
respectively. Touch the probes to the capacitor. Always observe polarity makings when measuring
capacitors.
6. Read capacitance value directly from the display.
7. After completing the measurement, disconnect the test leads.
Note:
With residual voltage afflicted capacitors and capacitors with poor insulation resistance may affect the
test result is negative.
