How To Use A Multimeter Voltage Tester

Set the voltage tester to ac or dc depending on the current you want to check.

How to use a multimeter voltage tester. What does it mean to check the voltage of live wires. Touch the black probe to one screw and the red probe to another. If the wires are exposed or you can reach the metal terminals you can use a contact voltage tester. How to use a multimeter to test voltage of live wires. 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.

You will get an introductory video of this multimeter whose link is given in the description of this video. A voltage tester does not tell you the exact amount of voltage. Use a voltage tester. Set the parameter to voltage step 3. If no voltage is present unscrew the fixture from the electrical box.

Connect the multimeter in series. Hold the black probe against the negative terminal and the red probe against the positive one. Connect the multimeter in parallel. Remove the bulb and test the contact in the bottom of the socket for voltage. Use the part labeled v and a wavy line to measure alternating current.

Plug in the probes step 4. Place the tester into the positive side of an outlet. The tester shouldn t indicate power since that is the negative terminal. Electrical outlets in homes use ac but car stereos use dc so make sure you know which you need to use. Also set your meter to the appropriate range.

Use the tester to check for power. Why is it important to check the voltage of a live wire. To get accustomed to using a multimeter test it on a battery. A non contact voltage tester is great especially for wires that are hidden behind insulation or a socket. 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.
