A few years ago, if you knew how to use a multimeter, you were probably an electronics technician or an engineer. But, today, the handy test equipment known as a Digital Multimeter should be in the toolbox of every handy person. The multimeter is great for determining the working status of many appliances. Multimeters are available in either digital or analog models. Digital multimeters will display readings in numbers. Analog multimeters indicate the value with a needle over a scale.
Have you ever wondered why a light doesn’t turn-on?
If the lightbulb is not bad, is the lamp out of order?
Is the lamp cord bad?
Here is one simple example of where a digital multimeter comes in handy. A useful function of a multimeter is the resistance, or “continuity” test function. To avoid the chance of electrical shock, it is important to never use the continuity test function on any appliance that has live voltage connected. Always make sure the appliance is first NOT connected to any power source.
To test a switch, place a test probe on each side (pole) of the switch. When you move the switch from the off to on position, the multimeter reading should change from zero to infinity. If not, then the switch is not working properly. To test a motor, touch a test probe to each pole. Again, a reading of zero indicates that the motor has continuity, current can pass through, and the motor windings are good.
After carefully studying the instructions of the digital multimeter, you will be able to move on to more detailed electrical tests. A multimeter can measure alternating current (AC or household current) or direct current (DC or battery current) in a live circuit. It can also check voltage. A multimeter can test 120 volts AC in a home circuit, or it can test DC batteries to learn if they are weak or fully charged.
Take the time now to learn how to properly use a basic multimeter. You will be glad you did when someday you would like to verify the cause of an everyday electrical problem.
