Test devices such as the walls of sockets with a multimeter. Repair of electrical equipment are better by a qualified electrician, as your domestic electricity supply can be dangerous. However, you can make a project to test fixtures with electronic multimeter. Multimeters, as its name indicates, test various components of the electricity in your home, such as the voltage and amps, allowing you to be more specific on problems if you need to call an electrician. It could also potentially save you, because the electrician did not need to work as diagnostic.Difficulty: ModerateRubber glovesScrewdriverMultimeter1
Identify the lighting you want to test. You can have the wall outlet that does not work correctly, or perhaps a light fitting or switch. All of these devices can be tested using an electronic multimeter.
2
Donning a pair of lightweight rubber gloves before testing lighting. This prevents you from get an electric shock if you touch a hot wire, as you have electricity for test fixtures.
3
Turn on the multimeter. Set it to measure voltage using the dial or buttons on the front of the counter. Ensure that you set the voltage on the meter of 120 volts, as this is the voltage of power supply in your home.
1
Insert the metal component at the end of the black wire of counter in the top hole in the wall socket; It is the connection to the ground.
2
Insert the metal component at the end of the thread in the lower left hole in the wall socket. It's the hot or direct connection.
3
Read the voltage displayed at the counter. He reads between 110 to 120 volts, if the wiring to the outlet works, which means it is not a problem with the fixture. If there is a reading, there is a problem with the cabling or a fault in the outlet, it is good idea to call an electrician.
4
Test the other wall jacks you have identified that may have a problem. Use the same method as before.
1
Remove the screws holding the switch in place cover with a screwdriver. Carefully pull the switch to you cover slightly so you can access the terminals of the switch.
2
Look at the terminals at the rear of the switch. The number of terminals depends on the type of circuit that the switch is connected. A switch that operates a single light has two terminals: an a a live black and is always hot, and the other is the brass and is hot when the switch is enabled. A switch that operates more than a light, or that is connected to a switch, has three terminals. Terminal screw is black, and the other two are brass. The black terminal is always hot, and the other two alternate according to what position the switch is set to.
3
Place the black part of the metal casing component, as it is ground. Bring the red part on the black terminal. Read the meter. It reads of 110 to 120 volts, if electricity is in place for the switch. If there is a reading, it is a fault in the wiring, so that you have an electrician.
4
Place the red component on terminal two brass screws. If there are two terminals choose one; Whatever one select it. Read the meter. If there is a reading, then the electricity is to obtain the fine switch. If it is not a reading, move the switch to the other position. The counter displays the voltage if the switch works correctly. If it does not have a reading, you replace the switch.
5
Repeat the process with the red on the other terminal pane, if the switch has more than one brass screw. Read the counter as before. If there is a reading, the switch is completed. If there are steps, and then move the switch to the other position and replay counter. If still there is not a reading, replace the switch. Replace the switch cover after you've tested the switch.
1
Turn on the light to check if it works. If this is the case, then it is not necessary to test further. If this is not, and then disable the switch.
2
Remove the bulb and put in a new. Turn on the switch again. If this works, then all is well. If this is not, then leave the switch in position "on". Remove the bulb of the attachment again.
3
Remove the cover of the fixture, so you can access these two terminals. Unscrew the lid with the fingers or use a screwdriver to remove the screw cover in place and then delete.
4
Look at the two cables connected to the terminals. One is black and hot when wireless switch is enabled. The other is white or grey, and the neutral wire that completes the circuit. Place the black pane on a metal part of the lighting unit. Place the red component on the connected terminal black wire.
5
Read the meter. If you get a reading, electricity is the light switch, the switch has a fault and needs replacing. If it reads zero, he y a fault in the wiring between the switch and light fixtures, you must have checked by an electrician.
If you are just unsure on lighting tests, call an electrician.
