Voltage tester – indispensable for every craftsmanWhenever a hole has to be drilled in the wall, every do-it-yourselfer asks himself the anxious question: Is there electricity in it? Here a voltage tester provides helpful services: The voltage tester finds electrical cables in the wall before the do-it-yourselfer has drilled a hole in it. What you should look out for when buying a voltage tester can be found here.Single pole or double pole voltage tester – What type of voltage tester is recommended?Basically there are two different types of voltage tester, the single pole and the double pole voltage tester. This distinction can also be made between single-phase and two-phase voltage detectors. Since a voltage tester can be used, for example, to check which conductor at the socket is the live one, the voltage tester is also referred to as a phase tester. With a single-pole measuring instrument, the test instrument must be connected to the measuring contact in order to check the voltage. The do-it-yourselfer then places his own finger on the other end of the voltage tester. If voltage flows through the contact, an indicator lamp on the voltage tester lights up. However, single-pole voltage testers are not highly recommended. These are only used by craftsmen for very simple tasks, such as mounting a lamp or a socket. On the one hand, a harmless current flows over the body during the test. And furthermore, this method of chip testing is unreliable. As soon as the do-it-yourselfer stands on a floor that does not conduct electricity, no electricity flows. This means that the indicator light shows no voltage even though voltage is present. This can be very dangerous for the craftsman. In contrast, bipolar voltage detectors do not have this problem. Here both contacts must be held at the point to be tested. Only when both contacts are connected does the voltage tester measure the electrical voltage and the indicator light is activated. However, to avoid dangerous situations, you should test each voltage tester at a safe location before use where you do not know if it is live. What additional functions should a voltage detector have? Many voltage detectors only have an LED indicator that indicates the presence of voltage, but does not measure an accurate value. If you want to measure the exact voltage, you should use a high-quality model from Fluke or Benning. Similar to a multimeter, these also display the exact voltage value. In addition, voltage detectors can also offer additional functions. For homeowners, the FI protection check function is a very useful function. However, this function can only be found on higher quality models. What other criteria should a voltage tester meet? The voltage tester should be made of a shatterproof and stable material, and be well processed. Especially do-it-yourselfers often have dirty or dusty and therefore slippery hands. Therefore, voltage detectors with a rubber grip surface are recommended. You should also make sure that the unit has been tested and inspected before purchasing.
