Checking Voltage? Here’s How To Use A Voltage Tester


Do You Want Problem Solving 26 Essential Computer Accessories?

A voltage tester is a fantastic tool that you can use to test voltage. Moreover, if you want to stay safe while checking the voltage, please start using a non-contact voltage tester. Without even touching the wires, you can determine if power is present or not. Sometimes, if you go ahead and touch the wires, you are most likely to get electric shocks if the power is on. Hence, this fantastic voltage tester will cause you no harm. Whenever it comes in contact with any hot wire, it will blink or make some peculiar sound. Thus, it will alert you about the flow of electricity through the wire.

Uses Of A Voltage Tester

A non-contact voltage tester works to detect electric fields of AC voltages. It lights up whenever there is electricity. Moreover, the process of building a voltage meter is also very simple. With the help of such a device, you can check for live wires without a meter device. Take a socket and a bulb, first. Then attach some wires to it, connect and touch the wires to the ground. Keep the other one for testing purposes.

How To Know If A Wire Is Live

With the help of a voltage meter, you can quickly determine whether an electrical cable is hot. However, you should always remember that more than one wire can be live at the same time. Now, you can check the wire by touching the tip of the tester. Check at the point where the cables are in the attached position. However, you should never be fast in doing these electrical checks. Go slow and always keep your eyes open. A non-contact tester is the safest device to confirm that power is off. Even before you touch the wire, you can easily know this. Always make sure to turn off the main switch before you begin any of testing of wires.

The Testing Procedure

Before checking, disconnect the wire and ensure that the two wires never touch each other. Now switch on the power and check which wire is hot. Moreover, you can check whether the voltage tester is working properly or not. If you touch the neutral wire with one lead and the heated wire with the other, the tester will give some indication. Now, touch the hot wire with one and the ground wire with another lead. If the tester works, you will understand that the ground wire is fit to use. Always ensure safety first as you carry out these test checks. Do not touch a hot or live wire.

While making the contact, hold the leads of the tester on the insulated portion. As soon as you finish the test, switch off the circuit immediately. If you have any problem or you do not feel comfortable with testing wires, always consult an expert electrician. If you do not take enough precautions, the consequences can be dangerous. So, ensure your safety before wire testing with a voltage tester.
