Step 1: How to Use a Digital Multimeter

Introduction to the use of digital multimeter

A digital multimeter can be used for voltage, resistance, current, continuity, resistance, and is used to test the capacitance of transistors and even the internal resistance of capacitors both in and out of a circuit.


A digital multimeter (DMM, DVOM) has a digital display and may also show a graphical bar graph representing the measured values. Digital multimeters are more common today due to their cost and accuracy, but in some cases, such as when monitoring rapidly changing values, analog multimeters are still preferred.


Step 2: Fluke Multimeter

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


These multimeters are well known as multimeters, it is an accurate multimeter and durable, most of the professional electronic repair engineers use this type of multimeter


Step 3: How to Measure Voltage Using a Multimeter

Voltage, potential difference, voltage or electric tension (formally denoted ∆V or ∆U, but often more simply V or U, e.g. in Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.


In the past, to make the voltage red, we would use a voltmeter, but nowadays it is more practical to use a multimeter, as it has multiple functions and you do not need a device for every application.


Step 4: Voltmeter Ammeter


AC voltage (Alternating Current) is the voltage and the current in the power plug is 120/110/220/240v and the property of this type of voltage/current is that it fluctuates in reverse at a rate of 50/60 Hz times/second. The main advantage of this type of voltage is in comparison with direct current.


DC is the direct type of voltage/current, it is associated with 12v/9v/1.5v batteries


Step 5: Test the Battery With a Multimeter

The multimeter has this special feature to detect voltage and you can select the appropriate voltage reading range and if it exceeds that voltage range the symbol bol 1 will appear on the multimeter LCD screen indicating that the voltage is above the selected range


Step 6: Continuity Check

In electronics, a continuity test is the process of checking a circuit to see if current is flowing through it (in effect, a complete circuit). A continuity test is performed by applying a small voltage (in series with an LED or noise-generating component such as a piezoelectric speaker). If the flow of electrons is inhibited by a broken conductor, a damaged component, or excessive resistance, the circuit is "open".


Step 7: Multimeter Symbol

Here you have a picture of a multimeter symbol

Basically, a multimeter is an electronic tool that can measure current,

Voltage and resistance. (You may have also heard them referred to as "multimeters.") Current is measured in amps, resistance is measured in ohms, and voltage is measured in volts. There are two main types of multimeters: analog and digital. While analog meters use needles to make measurements, most people today use digital multimeters. Digital multimeters are generally more accurate and give more consistent readings.


Step 8: Inside the DMM

Here you can quickly understand the complexity and difficulty inside a digital multimeter, these devices help

Electronics enthusiasts at most test the basic forms of voltage, current, continuity, resistance and after you master all these steps, you can buy a professional multi-function tester and spend more, but before that, you can experience a cheap and reliable tester
