How to Use a Multimeter – Beginner’s Guide
In this text, we will show you a way to use a multimeter. This article is especially for novices who are new to electronics and don't have any idea approximately the use of a multimeter and what it's miles for. We will discover the maximum not unusual capabilities of a multimeter and a way to measure modern-day-day, voltage, resistance, and the manner to check continuity.
Recommended reading: The first-class multimeters beneath $50.
What is a multimeter and why do you want one?
A multimeter is an honestly necessary size device in electronics. It combines three important competencies: a voltmeter, an ohmmeter and an ammeter, and in some instances continuity
A multimeter allows you recognize what is going on on your circuits. Whenever some thing for your circuit isn't always going for walks, the multimeter will help you troubleshoot the hassle. Here are a few conditions in electronics tasks where you could locate the multimeter beneficial:
Is the prompt?
Does this twine behavior electricity or is it damaged?
How an awful lot modern-day is going via this led?
How an entire lot strength do you have got left in your batteries?
These and one of a kind questions may be replied with a multimeter.
Selecting a multimeter
You can discover a huge sort of multimeters with specific traits and accuracies. A fundamental multimeter prices about $5 and measures the three handiest however most essential values on your circuit: voltage, modern-day, and resistance.
However, you can wager that this multimeter will not final longer and isn't very correct. The exceptional multimeter for you may depend on what you ought to do, whether or not you are a amateur or a expert electrician, and your price range.
If you want help selecting a multimeter, test out our Maker Advisor article on the super multimeters under $50.
Get familiar with a multimeter
A multimeter is made of four crucial sections:
Display: this is wherein the measurements are displayed
Select button: choose out what you need to measure
Ports: that is wherein the probes be part of
Probes: A multimeter comes with probes. Usually one is red and the alternative is black.
Note: There isn't always any difference most of the purple and black probes, best the coloration.
So, assuming the convention:
the black probe continues to be related to the COM port.
The red probe connects to one of the other ports relying on what you want to diploma.
Ports
The "COM" or "-" port is in which the black probe want to be connected. The COM probe is normally black.
10A is used at the same time as measuring big currents, above 200mA
µAmA is used to degree contemporary
VΩ permits you to measure voltage and resistance and check continuity
These ports can also vary relying on the multimeter you are the use of.
Measurement voltage
It can degree DC voltage or AC voltage. The V with a right now line way DC voltage.
The V with the wavy line stands for alternating voltage.
To diploma voltage:
Set the mode to V with a wavy line in case you are measuring AC voltage or V with a at once line in case you are measuring DC voltage.
Make sure the pink probe is installed to the port with a V subsequent to it.
Connect the purple probe to the high-quality thing of your factor, in which the modern is coming from.
Connect the COM probe to the opportunity aspect of your component.
Read the value on the display display screen.
Tip: To diploma voltage you have to be a part of your multimeter in parallel with the factor whose voltage you need to diploma. Placing the multimeter in parallel consists of placing each probe throughout the leads of the factor whose voltage you want to degree.
Example: measure the voltage of a battery
In this situation, we are going to degree the voltage of a 1.5V battery. You recognise that it is going to be round 1.5V. Therefore, you need to pick out a variety with the pick out button that can look at 1.5V. So you need to select out 2V inside the case of this multimeter. If you've got were given an car-ranging multimeter, you don't want to worry approximately which range to pick out.
What would show up if you did now not recognize what the price of the voltage is? If you need to degree the voltage of some thing and you do now not recognise the range that the fee will fall into, you need to attempt numerous stages.
If the variety you selected is much less than the real price, the show will show 1 as shown in the picture underneath. The 1 technique the voltage is above the range you chose.
If you choose a better variety, most of the time you'll be able to take a look at the voltage fee, but with a whole lot less accuracy.
