How To Use A Multimeter Voltage Tester

In this video i go through the basic functions of a cheap multimeter i cover how to measure ac and dc voltage how to measure resistance how to test for co.

How to use a multimeter voltage tester. Use the tester to check for power. If you re attempting to test live wires find the screws pinning the wires in place. A voltage tester does not tell you the exact amount of voltage. Use a voltage tester. Place the tester on the negative side of the outlet.

Milli meters are designed to cater to three different parameters thus measuring voltage set the selection knob to voltage mode. Hold the black probe against the negative terminal and the red probe against the positive one. Connect the multimeter in parallel. If the wires are exposed or you can reach the metal terminals you can use a contact voltage tester. 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.

Connect the multimeter in series. We have started video tutorial series on how to use multimeter in our channel being engineers and in this video we will show you how to safely measure ac voltages using multimeter. Electrical outlets in homes use ac but car stereos use dc so make sure you know which you need to use. To get accustomed to using a multimeter test it on a battery. How to use a multimeter to test voltage of live wires.

Touch the black probe to one screw and the red probe to another. Place the tester into the positive side of an outlet. Set the voltage tester to ac or dc depending on the current you want to check. Pull it out and test the other wires in the box as before. Plug in the probes step 4.

What does it mean to check the voltage of live wires. Why is it important to check the voltage of a live wire. Before you test voltage check if the wires are live. If no voltage is present unscrew the fixture from the electrical box. If everything is ok the tester should give you a visual or sound indication that the wire is live.
