Final answer:
The correct procedure involves disconnecting the capacitor from its circuit, connecting the meter's leads to the capacitor's leads, and setting the LCR meter to the appropriate range (Option 2).
Step-by-step explanation:
To measure the capacitance of a capacitor using an LCR meter, the correct steps include: Option 2: Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and set the meter to the proper range. This process ensures safety and accuracy.
It is crucial to first disconnect the capacitor from the circuit to prevent measuring the equivalent capacitance of the entire circuit or causing damage to the meter. Then, the meter's leads must be securely connected to the capacitor's leads.
Lastly, setting the meter to the correct range is essential for obtaining a precise measurement. LCR meters are capable of measuring a range of capacitance values, and selecting the proper range helps avoid overloading the meter and ensures the display will show a value within its measurable limits.
