Touch the remaining probe from the multimeter to the side of the light bulb base along the threads.

How to use voltmeter light bulb. This article describes how to test for voltage. If you read 120 volts the light fixture is good. Mags how to videos how to use a multimeter for beginners in this video i will help teach you how use a multimeter to test volts ac dc amps and ohms. Turn the dial on the front of your multimeter clockwise to move it away from the off position. The multimeter will emit a low voltage through the probes that will test whether the bulb has been burned out.

Keep turning it until you land on the diode setting. Using a multimeter to test a two fila. Turn the multimeter dial to the diode setting. Before using a voltmeter for the first time learn how to set the device correctly and test it out on a low voltage circuit such as a household battery.
