The multimeter should now display a reading of 120 volts or slightly above. You've now confirmed that house electrical power (120 volts AC current) is reaching the switch, coming from the wire on ...

Switch the multimeter to measure resistance at its lowest setting, and test across the fuse. A reading of OL, or significantly higher than 20 ohms, suggests the fuse is blown.

If all appears to work properly, use a multimeter to test the switches for continuity. With the multimeter set on Rx1, touch the probes to the switch terminals. The reading should be at or near zero.

For added convenience, this multimeter features automatic ranging (more on that down below) and comes with test leads and a thermocouple with the required adapter.

For all of you who have a multimeter thrown in a drawer or toolbox but don’t know how to use it, these instructions will help in your search for missing voltage.

If your power supply has an on/off switch, turn the power supply on. Switch your multimeter to the range that is appropriate for reading the voltage from your power supply.

When your car doesn’t start, often the battery is the culprit. Unfortunately, most vehicle owners do not check their battery until it fails. As preventative maintenance, the suggested best practice is ...
