A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to
view if there is voltage present on a circuit. By doing so, a multimeter can help you achieve a variety of useful tasks, such as measuring ohms, volts, and amps.[1]

If you want to use a multimeter to check for AC or DC voltages, adjust the selector switch to the highest selection provided for AC volts. By starting high and working downwards, you will avoid damaging the meter by exposing it to a greater voltage than expected. Insert the black probe in the COM or negative jack, and insert the red probe in the V or positive jack, then insert the other ends of the probes into an electrical outlet and read the display on the multimeter. To learn how to measure resistance or amperes with the multimeter, keep reading!
