If there is a straight line adjacent to the “V”, then it is used to measure DC Voltage. The Voltmeter section of the Multimeter is usually marked as “V” and depending on AC or DC measurement, there will be additional indications. Using a Digital Multimeter, you can measure both the DC and AC Voltage. So, let’s get started.Ĭlick Here To Know OHM Meter vs Multimeter Measuring Voltage
#HOW TO USE A MULTIMETER HOW TO#
As a bonus, I will also show you how to test a Diode using DMM. Finally, I will how you how to test for continuity. Then we will proceed to measure DC Current by building a small LED circuit. We will see the procedure for measuring both DC Voltage and AC Voltage. First, I will show you how to measure Voltage using a Multimeter. Now that we have seen a little bit about Multimeter and its parts, let us proceed with main topic i.e., how to use a Multimeter to troubleshoot our circuits. LCD Backlight in a Multimeter How to use a Multimeter? This is useful if you are using the Multimeter in field with poor lighting. Some Multimeters come with backlight for the LCD display. Be very careful when using this port and do not use this port for long continuous durations (not more than 10s). WARNING: The 10A port will usually be marked whether there is an internal fuse or not. Use the other port with label 10ADC to measure DC Current up to 10A. In this configuration, you can measure AC and DC voltage, DC current in mA and Resistance, which is what most of us will use a Multimeter for. The Red probe is usually connected to the port with label VΩmA. Multimeter ProbesĪlways connect the Black probe to the COM port. Plug-in the probes in to ports of the Multimeter to make a measurement. Usually, every Multimeter comes with a pair of probes, one Red and one Black. But in our basic meter, we have to manually set the range. These meters are known as Auto Ranging Multimeters. Some advanced (and slightly costly) Multimeters can automatically adjust the range of the value being measured. You can set the parameter to measure using the selection knob at the center. The measured value, whether it is voltage, or current or resistance, is displayed on the LCD Display of the Multimeter.
Check if the wire is conducting electricity or not.Ī basic Multimeter consists of four parts.Measure the amount of current flowing through a device, like an LED.Check if the switch (or push button) is properly working or not.In addition to this, “modern Digital Multimeters (DMM)” allow you to measure resistance and also test for continuity. Irrespective of the size or price, every Multimeter can measure the most basic parameters like Voltage and Current. Coming to the price, basic Multimeters are available from as little as $5 while certified and calibrated Multimeters cost about $5,000. There are bench Multimeters, handheld Multimeters and “ clamp meters” in terms of different shapes and sizes. Multimeters come in different shapes, sizes and price points. It is a very essential tool for electrical and electronics engineers and is usually the first thing to use when troubleshooting a circuit.
Hence, the name “Multi” meter, as it combines the functionalities of Voltmeter, Ammeter and Ohmmeter into a single device. A Multimeter, also known as Multi tester, is an electronic measuring instrument which can measure Voltage, Current and Resistance.
