If you want to know more about a multimeter, you have definitely come to the right place. A multimeter is basically a 3-in-1 device used in measuring current and other parameters when troubleshooting an electrical device. It measures, voltages, resistance, and electrical currents. Some of them can be used in measuring other parameters such as continuity, temperance and frequency. There are different ways of measuring these parameters using a multimeter. The way you measure voltage will not be the same way you measure resistance. This article will provide basic guide on how to measure resistance and voltage using the multimeter.
Safety first
Before doing any measurements with a multimeter, it is very important to take safety precautions to avoid any hazard that may arise. Remember that if proper care is not taken, it can damage your device and even lead to death. Ensure that the battery is properly charged before you make use of the device. Also, do not take measurements above the meter’s voltage. You may also need to switch off the power before measuring resistance. This will prevent any form of electrical shock. Another vital safety precaution to take is to find out the denotations and meter involved in the measurements. Find out the connection ports, the position of the functional dial, the leads and the different readings for all parameters you want to measure. It is always better to stay safe before using a multimeter on an electronic device.
Voltage measurements
Voltage measurements measure the electrical potential in a circuit. Here, measurements are denoted in V, either in DC voltage or AC voltage. DC means direct current while AC refers to alternating current. Voltage measurement is the most common type of measurement with the mutimeter. It is measured with the voltmeter function of the multimeter. When measuring, the meter function is switched to the V section of the meter, where the test leads (black and red) are connected to the multimeter. The black lead is connected to the COM terminal while the red lead is connected to the VΩ terminal. Once these terminals have been connected, you can then take your measurements.
Resistance
Resistance is denoted as Ω and is measured in ohms. It refers to the extent at which an electric current reacts against a conductor. Before measuring resistance, you need to disconnect the power connecting the circuit you intend to measure. This will make sure you are not exposed to dangers or electrical hazards. After the disconnection, you will need to turn the functional dial to the Ω on the meter. Next, the black lead is connected to the COM terminal while the red lead is connected to the VΩ terminal before taking measurements. To effectively measure resistance, you need to connect both leads (black and red) to the specific circuit. This procedure will help you find out the ohms readings that show how much resistance is available in the circuit. The above are the basic steps to take when measuring voltage and resistance using a multimeter.
