Intro: How to Use a Multimeter Basics

A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.

There are many types of multimeters for many applications but in this tutorial, we will take apart just the most common ones and not that expensive.

Step 1: How to Use a Digital Multimeter

A digital multimeter can be used for voltage, resistance, current, continuity, resistance, capacitance to test transistors,even the internal resistance of capacitor in /out the circuits.

Digital multimeters (DMM, DVOM) have a numeric display, and may
also show a graphical bar representing the measured value. Digital multimeters are now far more common due to their cost and precision, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly varying value.

Step 2: Fluke Multimeter

Fluke Corporation, a subsidiary of Fortive, is a manufacturer of industrial testing equipment including electronic test equipment. It was started in 1948 by John Fluke, who was a friend and roommate of David Packard, future co-founder of Hewlett-Packard, when both were employed at General Electric.

These multimeters are the high end of multimeters well known as a precise multimeter and durable most professional electronic repair engineers use this type of multimeters

Step 3: How to Use a Multi Meter for Voltage

Voltage, electric potential difference, electric pressure or electric tension (formally denoted ∆V or ∆U, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.

In the past, for reding just voltage we will use a voltmeter, but more practical this days is to use a multimeter because is got multiple functions and you don't need a device for each application.

Step 4: Volmeter Ammeter

You have to remember that measuring voltage is very easy and all of the new multimeters have build in the auto function to detect the voltage or if not they have the option to choose from AC/DC.

AC voltage (alternating current) is the voltage and current in our mains plug 120/110/220/240v and the property of this type of voltage/current is fluctuating back-forward 50/60 Hz times/second the main advantage of this type of voltage is the very long distribution range in comparison with DC.

DC voltage is a straight type of voltage/current and is associated with batteries 12v/9v/1.5v

Step 5: Test Battery With Multimeter

The multimeter has this special function where it can detect the voltage and you have the option to choose the range for your appropriate voltage reading and if somehow you will exceed that voltage on the multimeter lcd screen will appear the symbol 1 meaning the voltage is above the range selected

Step 6: Continuity Check

In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit).
A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Step 7: Multimeter Symbols

You have here a picture of a multimeter symbols

Essentially, a multimeter is an electronic tool that measures current,
voltage, and resistance. (You may also have heard them referred to as “multitesters.”)Current is measured in amps, resistance is measured in ohms, and voltage is measured in volts. There are two main types of multimeters: analog meters and digital meters. Though analog meters use a needle to render measurements, today most people use digital multimeters. Digital multimeters are usually more accurate and offer more consistent readings.

Step 8: Inside a Digital Multimeter

Here you go a quick pick to see inside a digital multimeter its not complicated but not easy as well these device help

electronic hobbyist to perform the most basics forms of testing voltage,current,continuity,resistance and after you master all these procedures than you can buy a professional multitester and spend more but till then you can play with a cheap and reliable one
