![]() Doing this will both ensure an accurate reading, and help to keep tools and equipment safe. When using a multimeter, the most important step to remember is to select a voltage or range that will be higher than the expected value of the component you plan to test. If you are checking for resistance, you will need to choose the Ohms setting, whereas you will need to choose either AC or DC if you are measuring voltage. ![]() First, determine what type of test you are performing, and select the appropriate setting. Multimeters make it easy to automatically check the condition of various electrical components, but you will need to learn to properly set up and use a multimeter for the most accurate readings. The testing process for voltage is similar to other multimeter tests, but individual multimeters may come with specific instructions. Like when testing resistance, voltage testing requires you to know the expected voltage range beforehand to appropriately set your multimeter and to know whether the reading indicates an issue or not. ![]() VoltageĪ voltage test is performed to assess the force of an electric current. Like when you measure for continuity, a resistance test involves placing the probes of the multimeter on either side of the component to get a reading. Always disconnect any device or component from an energy source before testing for resistance. Various parts and components have different strengths, so before you test a part, you need to know how much resistance it should have. ResistanceĪ resistance test is performed to determine how much current is lost during its journey through an electrical component. A reading of ‘1’ or ‘open loop’ indicates that the component is non-continuous, and does not allow electricity to flow through it. If the resulting reading is at or around ‘0’, the component is continuous. When testing for continuity, you place the probes of the multimeter on either side of the component. ![]() Among various functions, multimeters are most commonly used to test continuity, resistance, and voltage: ContinuityĪ continuity test is performed to determine whether two items are electrically connected, allowing an electric current to flow from one to the other. Multimeters are used to troubleshoot electronics by detecting where connectivity problems may lie within a given electronic, and by diagnosing the type of issue – or at least indicating to the technician what their next step should be. What Is a Multimeter?Ī multimeter is a tool used to measure several functions of an electrical component to assess its condition. Here, we will cover everything you need to know about using a multimeter, and conducting safe testing and troubleshooting practices with ESD workbenches and in an electrical lab or environment housing sensitive electronics. ![]() Both analog and digital multimeters can give you a variety of readings in this guide, we will cover basic instructions for testing electrical components with a digital multimeter. Multimeters are one of the most common tools used to test electrical components and is vital for any toolbox. When working with electrical components or in an electrical environment, troubleshooting and testing devices to assess their condition is vital to maintain a safe, efficient workspace. ![]()
