Step-by-Step Guide
3. Putting Your Knowledge to the Test
Alright, with your tools ready and safety precautions in place, it’s time to check the voltage! First, locate the outlet you want to test. Make sure it’s easily accessible and well-lit. You don’t want to be fumbling around in the dark with electrical equipment. Shine a light in there. Really. Inspect the outlet for any obvious signs of damage, such as cracks, burns, or loose wires. If you see anything that looks suspicious, don’t proceed. Call an electrician instead.
Next, set your multimeter to the AC voltage setting. This is usually marked with a “V~” symbol. The range should be set to a value slightly higher than your expected voltage (typically around 120V in North America). Insert the multimeter probes into the appropriate slots on the meter. Usually, the black probe goes into the “COM” (common) slot, and the red probe goes into the “V” (voltage) slot.
Now, carefully insert the multimeter probes into the outlet slots. The black probe goes into the neutral slot (the wider one), and the red probe goes into the hot slot (the narrower one). Make sure the probes are making good contact with the metal inside the slots. If you’re having trouble, try wiggling them slightly. But be gentle! You don’t want to break anything.
Finally, read the voltage displayed on the multimeter. In North America, the standard voltage is around 120 volts AC. If the reading is significantly higher or lower than this, there may be a problem. Write down your measurement for future reference or troubleshooting. If you’re getting a reading that’s way off, double-check your connections and settings. If everything looks right and the voltage is still out of whack, it’s time to call in a professional.
