Tips: How to use capacitance function of a clamp meter?
To avoid damage the clamp meter or the device under test, disconnect all power supply to the circuit under test and fully discharge all high-voltage capacitors before measuring capacitance. Use DC voltage function to determine the capacitor has been discharged.
- Turn the rotate dial to capacitance function.
- nsert the black test lead into the COM jack, and the red test lead into the capacitance jack.
- After the capacitor is fully discharged, connect the other end of the red and black test leads to the two ends of the capacitor under test. The measured capacitance value is read by the LCD display.
Note:
- To improve the accuracy of measurements below 10nF, subtract the distribution capacitance of the meter and leads.
- When measuring large capacitance, stable reading takes a certain amount of time.
- When measuring polar capacitor, pay attention to the corresponding polarity to avoid damaging the instrument.
