How To Use A Multimeter Voltage Tester

Milli meters are designed to cater to three different parameters thus measuring voltage set the selection knob to voltage mode.

How to use a multimeter voltage tester. Before you test voltage check if the wires are live. Why is it important to check the voltage of a live wire. The tester shouldn t indicate power since that is the negative terminal. You will get an introductory video of this multimeter whose link is given in the description of this video. Hold the black probe against the negative terminal and the red probe against the positive one.

To get accustomed to using a multimeter test it on a battery. Connect the multimeter in parallel. Remove the bulb and test the contact in the bottom of the socket for voltage. Use a voltage tester. Taking your reading cautions of checking the voltage of live wire.

Place the tester on the negative side of the outlet. Connect the multimeter in series. Use the tester to check for power. Set the parameter to voltage step 3. Use the part labeled v and a wavy line to measure alternating current.

Set the voltage tester to ac or dc depending on the current you want to check. If no voltage is present unscrew the fixture from the electrical box. 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. If the wires are exposed or you can reach the metal terminals you can use a contact voltage tester. Plug in the probes step 4.

What does it mean to check the voltage of live wires. A voltage tester does not tell you the exact amount of voltage. If you re attempting to test live wires find the screws pinning the wires in place. Pull it out and test the other wires in the box as before. Make sure the light switch is in the on position.
