Voltage-tester screwdriver | Everything you need to know
When carrying out electrical work, safety and checking that all the equipment does not have any type of current is one of the most important points. If we do not cut the current we can have a good scare. If you want to check that you have cut off the current the simplest tool that we can use for it is the screwdriver. At the same time, with this tool we can check the correct operation of all the plugs of an installation, for example. But, do you know what a voltage-tester is?
What is a voltage-tester screwdriver?
A voltage-tester screwdriver is a tool that, unlike a screwdriver, is not used to loosen or tighten screws, but is a tool that has a metal tip on one side and an insulated handle on the other, which contains a small resistor inside and is used to see if an electric current is flowing through a pole. Its use is very simple, we simply have to touch the metallic tip with the cable and to place the finger in the ass of the handle. If current is flowing through the wire we have touched, a lamp will light up inside, if not, it is a neutral pole through which no current is flowing.What can we check with a voltage-tester screwdriver?
With the voltage-tester screwdriver we will be able to detect if there is electric current in an installation or to see installations that are not properly insulated. To do this, simply place the tip on the cable to be checked and your finger on the back of the tool.¿What type of voltage-tester screwdriver exist?
As we have mentioned, the pin finder is a tool with which we can check if an electric current is flowing through a cable. To do this, we have different types of screwdriver based on the current we want to measure. In the case of the Bianditz voltage-tester screwdriver, we can measure between 100 – 500V.
