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. Once you do that test it with the chassis to ensure that it is still zero. When the probes part the screen should read 1 or ol also known as open circuit. Whenever something in your circuit isn t working the multimeter will help you troubleshooting.

Test your multimeter is working by pressing the probes together. How do you use a multimeter. To bring the meter to zero you have to touch both the leads together. This is usually 200 ohm. You simply dial the proper function and scale touch the two test leads to the wiring or device in question and check the meter reading.

Use a multimeter on these test points to see if the voltage measured matches the labeled test point voltage. A multimeter allows you to understand what is going on in your circuits. Bring out your multimeter and adjust it to the lowest setting. Find the two connections where wires connect to your part. Even if you don t have an electrical schematic of the circuit board which would identify components and give you the voltage and resistor values that should be present many circuit boards have test points that are clearly labeled.

The multimeter screen should read 0 00 also known as short circuit inexpensive meters may read close to this from resistance of their leads. Open your computer to find the motherboard. Remove the atx connector from it. A multimeter is a black box of electronic circuitry that allows you to troubleshoot just about any type of electrical wiring or device.
