How to use voltmeter light bulb. Touch one probe from the multimeter to the very bottom centre of the light bulb. Checking for 120 vac on a light bulb socket assembly. Checking a common light bulb using a multimeter on the ohm scale. Using a multimeter with the selector switch in volts ac position. The multimeter will emit a low voltage through the probes that will test whether the bulb has been burned out.
Touch the voltmeter to the input wires or connections. Brake and turn signal light bulb for a auto or trailer. 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. If the bulb is in working order the multimeter will show values from fifteen to twenty. Turn the multimeter dial to the diode setting.
