How do you test a 120 volt with a multimeter?
Set a multimeter to measure voltage. Insert a probe into each slot and read the line voltage measurement. A properly working outlet gives a reading of 110 to 120 volts. If there is no reading, check the wiring and the outlet.
Where is the continuity setting on a multimeter?
Turn the dial on the multimeter to the continuity setting. Generally, the continuity mode will have a diode symbol, which is a triangle with a line on the right side. It may also have a symbol that looks like soundwaves.

- Touch the test probes of your digital multimeter together.
- Press the calibration knob until the display reads “0” on the digital multimeter if you don’t see “0 ohms” initially.
