What is a Voltage Tester?
A voltage tester is a multi-role detecting tool by which you can detect voltage in an electrical wire or outlet and socket. You can also test the voltage at any point in a circuit. These tools are widely used to check the electrical wire is life or not.
The advantage of this voltage tester is you can test the voltage at any specific point. You can also measure the level of the voltage with the same tester. They have a wide range of operation and they will indicate you the voltage of different levels like low, moderate or high voltage.
You can measure and test one-point voltage or you can also use test lead to measure the voltage across two points. These voltage testers are lightweight and compact so that you can easily carry them and use them in different conditions.
How Does It Work?
A voltage tester has one or two metal that needs to be connected with the electrical wire or the outlet pin. Thus, some amount of current will pass to the tester and there is a tester circuit inside the voltage tester. The tester circuit is in parallel connection so that, it will not make any significant change to the main electrical circuit.
The tester can detect and measure the level of the voltage and if there is a display, it will show the exact numerical number on the display. But most of the voltage tester has an indicator in which, for a fixed amount of voltage it will lit up. Thus, you can understand the level of the voltage.
Best Voltage Tester Buying Guide
To distinguish between an ordinary voltage tester and the best voltage tester you need to the factors that are essential to be the best. Here some of the important things you need to look up before buying a voltage tester.
The test probe of the tester is important as they connect the tester with the wire or the pins of the outlet and collect the current from it. If they are good and made of well quality metal then they will be able to pass the current accurately that is very important for accurate testing.
Indicators must be in well LED and in good numbers. One should easily understand them and should distinguish the voltage levels. There may also be some sound alert of different frequency to indicate a different level of the voltage. The sound also needs to be loud enough so that you can get the difference between sounds.
The range of the voltage tester indicates how much and how low voltage you can detect with the tool. The range of the voltage tester needs to have a wide range so that you can use it for various kinds of works. And the tester also should have a different model for the different ranges for better accuracy and operation.
Method of Testing
The method of testing is the way you need to measure and detect. if the voltage tester has a non-contact voltage testing feature than it will be good to use in the remote and low space area. But if you want to detect a wire that has a lot of live wire around it, then you should not use a non-contact voltage tester as it will be affected by the other live wire.
Design and Size
The design and size of the voltage tester need to be small and compact and at the same time lightweight so that you can easily carry the tool with you and use them in comfort. A pocket clip will make it easy to carry it in your pocket.
Voltage Tester vs Multimeter
There is some difference between a multimeter and a voltage tester. A voltage tester is used for detecting the availability of voltage in the electrical wire of any point of a circuit. They can also measure the level and intensity of the voltage. They are useful to check electrical lines as well to assume the amount of voltage in the line.
On the other hand, a multimeter is a multipurpose meter by which you can measure many parameters in different ranges. They show the result in a display and by changing the operating mode, you can measure different parameters of electrical equipment or the power line current, voltage, resistance, capacitance, frequency and so on.
A multimeter is not as handy as a voltage tester but you can measure a lot of things where just voltage in a voltage tester. Again, you will not get the exact amount of voltage in most of the voltage tester. But they are simple and easy to use and carry so if you need to know only about voltage property, then a voltage tester will be perfect for you.
Frequently Asked Questions (FAQs)
There may arrive a lot of questions on your mind about the best voltage tester. Here some of the Frequently Asked Questions (FAQs) and their answers:
Q. Do I need an extra test lead to use the voltage tester?
Ans: No, you don’t need any extra test lead as they have built in test lead with enough space to hold them with the tester.
Q. Can I distinguish between high and low voltage?
Ans: Yes, you can distinguish the levels of the voltage from the indicating LED lights and also from the sound alarm.
Q. How to read the voltage level from the indicating LED and sound?
Ans: If there are more lights lit up that indicates higher voltage where a low amount of LED indicated lower voltage. Again, different frequency indicates different levels of voltage.
To check weak electrical wires and points on an electrical circuit is very important to secure the proper safety and prevent short circuits. Use the best voltage tester to check them as you can do this faster and accurately than any other tool with an indication of the voltage level. Always be aware of the method and ensure the proper safety of every step.
