Identifying which slot is the hot side of the receptacle 

Identifying which slot is the hot side of the receptacle 

Using a multimeter like the UNI-T UT33B multimeter, or any other multimeter you’re using, the next step is to identify which slot is on the hot side of the receptacle. This can be done by looking at the slots on the receptacle and noting which one has an extra conductor connected to it or a stripe painted around it.

Once you have identified the hot side of the receptacle, you can use your multimeter to test for voltage. To do this, ensure the multimeter is on a setting that will measure AC volts. Then attach one end of the meter’s probes to each of the slots in the receptacle and note what it reads. If no power is running through, you should see a reading of 0V. 

Testing for continuity on the ground or neutral side of the outlet

Testing for continuity on the ground or neutral side of the outlet

Once you have tested for voltage, you should also check for continuity on either the ground or neutral side of the outlet. To do this, switch your multimeter to an ohm setting and attach one probe to each slot in the receptacle. You should see a reading of 0 ohms if there is no issue with the connection. 

Troubleshooting issues with a multimeter – if there’s no power or continuity, what should you do next

If your receptacle is not working or the readings are incorrect, using a multimeter like the UNI-T UT161E multimeter, or any other multimeter you’re using, can help identify the issue. It may be necessary to know how to test a receptacle with a multimeter. After this, decide to repair or replace the outlet. If you suspect an issue with any of the wiring in the system, then it is best to contact a certified electrician who can help diagnose and fix any electrical problems.
