How to use a Multimeter When measuring resistance, connect the probes of the multimeter in parallel with the resistor or load that you're testing and make sure you're not touching the probes or the load to get a more accurate result. For everything except measuring current, you will place the probes across the circuit you’re testing.

So you can see the ohms the upside down horseshoe symbol here. And this can also measure measureMoreSo you can see the ohms the upside down horseshoe symbol here. And this can also measure measure diodes capacitors and it can give us an indication. Then finally we can measure frequency in hertz.
How to use multimeter for beginners?
Feb 13, 2022 · Today you will learn how to use a multimeter by measuring the values of this DIY emergency modem power supply. The goal is simple. Take a 20-volt power tool battery and lower its voltage to meet the power requirements of a 12-volt modem. This project will use a buck converter (step-down converter), a diode, a few wires, and of course the multimeter.

Test Your Probes or Leads
- Set your multimeter to the ohm meter on the selector knob.
- Plug the black probe into the common port.
- Insert the red probe into the jack marked for ohms.
- Gently tap the red and black tips together. ...
- Your reading should be 0.5 ohms or less.
- If your reading is higher than that, replace the probes.

What is the purpose of using multimeter?
A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.
What is a digital multimeter used for?
Digital multimeters are measuring instruments that can measure quantities such as voltage, current, and resistance. Measured values are shown on a digital display, allowing them to be read easily and directly, even by first-time users.
What does it mean when a meter has a high impedance?
In electronics, high impedance means that a point in a circuit (a node) allows a relatively small amount of current through, per unit of applied voltage at that point.
What is a multimeter?
So, the complete definition can be as follows. Multimeter is an electronics device we use for measuring electrical quantities and troubleshooting devices. I hope this is making sense to you. We can use a multimeter for troubleshooting PCB boards, for circuit continuity testing as well.
Is a multimeter dangerous?
A multimeter can measure both of them with greater accuracy depending on manufacturing quality. A bad multimeter is a waste of time and money and if you are using it for high voltages it can be deadly dangerous as well. I use the word deadly dangerous not to scare you but to remind you of safety.
Why is the function selector button on a multimeter called a function selector button?
So to select among the different functions of multimeter i.e. to select voltage, current, and resistance measurements , we use a round big button called the function selector button.
What is a clamp meter?
We need a safer multimeter, called the clamp meter. These meter uses electrical induction methods to measure voltages and currents. Shortly we will see how to measure voltages by a multimeter. There you will have an idea why a clamp meter is a must tool if we are dealing with high voltage electrical circuits.
What is the other basic electrical we want to measure in electronics all the time?
Current is the other basic electrical we want to measure in electronics all the time. Most of the time we really need to know what current our load is driving or what branch in the circuit has how much of current, and the list goes on.
Is learning electronics fun?
Learning electronics is fun. It’s awesome to know how different devices around us work. You know, Yaman Electronics is a dedicated site where I talk about electronics but here in this specific article, we will just keep ourselves to multimeter basics for beginners and will learn how to use a multimeter for a certain set of measurements.
What is a multimeter used for?
They’re very versatile and can be used to characterize an embedded system or troubleshoot a non-functioning lightbulb in your house. Let’s discuss what it is and how to use it.
What are the different types of multimeters?
Different types of Multimeters - Analog and Digital (Clamp, Pen type, SMD tester, Benchtop, etc.) Multimeters come in a variety of sizes and packages. And until the last couple of decades, all multimeters were analog but now digital multimeters are much more common. You can also find portable multimeters that are battery operated ...
What do digital multimeters measure?
Many, many other, but less common, things. Digital multimeters nowadays are not just limited to voltage, current, and resistance measurement. They can also measure capacitance, diode condition, frequency, transistor type, and more. You may have heard of ohmmeters (measures resistance) and ammeters (measures current) and voltmeters ...
Is a multimeter digital or analog?
And until the last couple of decades, all multimeters were analog but now digital multimeters are much more common. You can also find portable multimeters that are battery operated and can be taken anywhere.
How to measure resistance?
When measuring resistance, connect the probes of the multimeter in parallel with the resistor or load that you're testing and make sure you're not touching the probes or the load to get a more accurate result. For everything except measuring current, you will place the probes across the circuit you’re testing.
