Doing your own electrical work can be a great way to save some money as well as get the job done withing the schedule. However, dealing with household current is dangerous and no fun because you can get an electric shock that can be fatal.
Before doing any electrical work, you need to make sure there is no electrical current flow in the circuit. For that, you will need to use a voltage tester. A voltage tester is a type of equipment that you use to measure current flow. Easy and safe to use, it is a tool that can really save you from a jolt.
Although many models of voltage testers are available on the market, a non-contact voltage tester is probably the simplest tool you can have on-hand. It allows you to quickly verify the presence of AC voltage on any type of electrical installation such as cables, sockets, fuses, switchboards, etc., and all that without direct contact. It is an inexpensive tool that not only homeowners should have in their toolbox but professional electricians too.
If you decide to buy a non-contact voltage tester, consider getting a model that comes with an audible alarm so you don’t have to pay close attention to the indicator light (which is usually difficult to do in full sunlight). Another feature that you may want to have is an integrated LED light on the tool, though this isn’t necessary.
Benefits of Using Voltage Testers
Dependable Results
When a voltage tester is used properly, it provides effective results. However, you need to make sure you use the right type of voltage tester for your application. Once you connect the device to the electrical circuit, it provides immediate readings.
Versatility
Voltage testers are designed to check both AC and DC currents. All you need to do is adjust your equipment to your desired current – depending on your needs. Know that homes and some smaller businesses use AC current, while car stereos, for example, use DC current. Before use, set the meter to the appropriate range to get accurate results.
Increased Value
When selecting a voltage tester, it is very important to consider and examine the load curve. If your intention is diagnostic testing, then consider the maximum value of insulation resistance that it can measure. Try to find out correct numbers to get maximum benefits from your device.
Using a voltage tester can help you avoid an accident and remain safe while working with electricity. So, make sure you have one before performing any electrical work in your home.
