1. Ensure that the power supply to the circuit or equipment is turned off and disconnected to prevent any accidents or damage.
2. Identify the terminals or pins that need to be tested for polarity. This could be the positive and negative terminals of a battery, power supply, or any other electrical component.
3. Use a multimeter set to the DC voltage measurement mode. Make sure the multimeter is functioning properly and the probes are in good condition.
4. Connect the black probe of the multimeter to the negative terminal or pin of the circuit or equipment.
5. Connect the red probe of the multimeter to the positive terminal or pin of the circuit or equipment.
6. Turn on the power supply to the circuit or equipment.
7. Observe the reading on the multimeter. If the reading shows a positive voltage, it indicates that the polarity is correct. If the reading shows a negative voltage, it indicates that the polarity is reversed.
8. If the polarity is reversed, turn off the power supply and disconnect it. Swap the connections of the probes (black to positive and red to negative) and repeat the test to confirm the correct polarity.
9. Once the correct polarity is confirmed, turn off the power supply and disconnect it before proceeding with any further testing or operation.
10. Document the results of the polarity test for future reference and troubleshooting purposes.

Materials:
- Polarity tester (or multimeter)
- Electrical outlet
- Known-polarity device (e.g., AC adapter)
Procedure:
1. Safety First: Ensure the electricity is turned off at the circuit breaker or fuse panel before handling any electrical components.
2. Check the Polarity Tester: Touch the known-polarity device's prongs to the tester. The tester should indicate which prong is hot (positive) and which is neutral (negative).
3. Identify the Outlet Prongs: Determine which prong in the outlet is hot (usually brass or copper-colored) and which is neutral (usually silver or nickel-plated).
4. Test the Outlet: Insert the tester's prongs into the outlet. The tester will indicate the polarity of the outlet.
- Correct polarity: Hot prong indicator lights up (or multimeter reads voltage).
- Reversed polarity: Neutral prong indicator lights up (or multimeter reads 0 volts).
5. Confirm Accuracy: If reversed polarity is indicated, test again to confirm the result.
Additional Notes:
- If the outlet has three prongs, the third prong is for grounding and does not have polarity.
- Some polarity testers also indicate if the outlet is properly grounded.
- If the outlet has reversed polarity, it should be corrected by a qualified electrician to prevent electrical hazards.
