Testing electronic components with multimeter pdf

Plug the two probes into the multimeter and set the dial to 'continuity. ' If you place the red and black probes on either side of the part (some parts have diodes and are one-directional so you need to arrange the probes accordingly), and you get a read of approximately zero, electricity can flow through the part.

What are the methods of testing electronic components?

7 Types of PCB Testing Methods

In-Circuit Testing. In-circuit testing (ICT) is the most robust type of PCB testing in existence.
Flying Probe Testing. ...
Automated Optical Inspection (AOI) ...
Burn-In Testing. ...
X-Ray Inspection. ...
Functional Testing.

How do you check for faulty electronic components?

How to Test Electronic Components

Continuity is the first thing to check. This tests if electricity can flow through the component.
Resistance is the next thing to test for.
Like the test for resistance, checking Voltage and the force of electric pressure requires a multimeter.

What are the 4 basic types of electronic components?

Resistors: Components used to resist current. Switches: Components that may be made to either conduct (closed) or not (open). Capacitors: Components that store electrical charge in an electrical field. Magnetic or Inductive Components: These are Electrical components that use magnetism.

How do you test a faulty component with a multimeter?

So what we need to do be able to do is test it as a continuous circuit from the wire to the plug by

How do I use a multimeter to test electricity?

Set a multimeter to measure voltage. Insert a probe into each slot and read the line voltage measurement. A properly working outlet gives a reading of 110 to 120 volts. If there is no reading, check the wiring and the outlet.

How do I know if my IC is damaged with a multimeter?

Take the terminal-cable from multimeter and connect it one by one to each of the pins of another side separately. If the beep sound occurs of there is a continuity in more than 50% of the combinations then there is a good chance of the IC to be shorted from inside.

What is the most common instrument used in testing electronic components?

There are many different forms of test instrument that can be used to test electronic equipment. The digital multimeter is one of the most common, but there are many other items of test equipment including the oscilloscope, signal generator, spectrum analyzer, logic analyzer and many more.

How do you test if a capacitor is working?

Use the multimeter and read the voltage on the capacitor leads. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should be replaced.

What are the 5 components in a circuit?

The following common components are used in most printed circuit boards:

Resistors. Resistors control the electric currents that pass through them, as well as the voltage in each component connected to them.
Transistors. ...
Capacitors. ...
Inductors. ...
Diodes.

What are the 6 components of a circuit?

Some basic circuit components which are used in an electronic system is given below.

Cell. A cell is a device used to power electrical circuits.
Switch. A switch is a device that can break an electrical circuit by diverting the current from one conductor to another conductor or an insulator. ...
Light Bulb. ...
Connecting Wires.

What are the 3 components of a circuit?

Every circuit is comprised of three major components:

a conductive "path," such as wire, or printed etches on a circuit board;
a "source" of electrical power, such as a battery or household wall outlet, and,
a "load" that needs electrical power to operate, such as a lamp.

How do you use a multimeter step by step?

I'm going to take oops the black probe and touch it to the negative side of the battery. And the red

Why is a multimeter is important in testing electrical component?

Before replacing components or making major repairs on a device, the first step most technicians take is to test a device's battery. Using a multimeter to test a battery's voltage, you can determine whether a battery is fully charged, in need of charge, burnt out, about to burn out, and so on.

What are the methods of fault finding?

Here are six key points to consider:

Collect the Evidence. All the evidence collected must be relevant to the problem at hand.
Analyse the Evidence. ...
Locate the Fault. ...
Determination and Removal of the Cause. ...
Rectification of the Fault. ...
Check the System.

How do you test if a wire is live with a multimeter?

Place the red (positive) probe on one wire and the black (negative) probe on ground. Once you position your probes, you check the multimeter for a reading. If the multimeter presents a reading of 120V (with wires for lighting) or 240V (with outlets for large appliances), then that wire is hot or live.

How do you test if a wire is live?

One of the easiest ways to know if a wire is live is to use a voltage checker or a current checker. These are simple devices that you can touch to any wire, and it will tell you if there is electricity running through it.

What are ohms a measurement of?

The ohm is the standard unit of electrical resistance in the International System of Units ( SI ). Ohms are also used, when multiplied by imaginary numbers, to denote reactance in alternating-current ( AC ) and radio-frequency ( RF ) applications.

How do you test a resistor?

One lead from the circuit. It doesn't matter which one next you will want to obtain an electrical

What happens if IC is damaged?

Identity Card (IC) holders may apply for a replacement if you wish to change your particulars/photographs. Those whose identity cards are damaged or defaced are required to apply for a replacement within 14 days from the date of damage/defacement.
