Voltage Tester Guidebook

Voltage tester – indispensable for every craftsman
Whenever a hole is to be drilled in the wall, every DIY enthusiast becomes anxious. Question: Is there electricity in there?
Here you enter voltage tester helpful services: the voltage tester finds electrical wiring in the wall before the home improvement has bored a hole in it.
What you should pay attention to when buying a voltage tester, you can find out here.
Single pole or two pole voltage tester – Which voltage tester Art is recommended?
Basically, there are two different types of voltage testers, the unipolar and the bipolar voltage tester , This distinction can also be made alternatively in single-phase and two-phase voltage testers. Since you can check with a voltage tester, for example, which ladderAt the socket is the live lead, the voltage tester is also referred to as a phase tester. In the case of a single-pole measuring instrument, the testing device must be connected to the measuring contact to check the voltage. The home improvement then places his own finger on the other end of the voltage tester. If voltage flows through the contact, a warning light on the voltage tester lights up. However, single-pole voltage testers are not very recommendable. Only for very simple tasks, such as the installation of a lamp or a socket these are used by craftsmen. Firstly, a safe current flows through the body during the inspection. And besides, this method of voltage testing is unreliable. As soon as the handyman is standing on a floor that does not conduct electricity, no electricity flows. That is, the indicator light shows no voltage, although there is voltage. This can be very dangerous for the artisan.
In contrast, two-pole voltage detectors do not have this problem. Because here both contacts must be kept to the point to be examined. Only when both contacts are connected, the voltage tester measures the electrical voltage and the indicator light is activated.
However, to avoid hazardous situations, you should test each voltage tester in a non-hazardous location before using it in places where you do not know if you are live.
What additional functions should a voltage tester have?
Many of the voltage detectors have only one LED indicator which indicates the presence of the voltage but does not measure an accurate value. If you want to measure the exact voltage, you should fall back on a high-quality model of the brands Fluke or Benning. These show similar to one multimeteralso the exact voltage value. In addition, voltage testers can also offer additional functions. For homeowners, the function of checking the residual current protection is a very useful function. However, this feature is only found on higher quality models.
What criteria should a voltage tester also fulfill?
The voltage tester should be made of a shatter-proof and stable material, and be well-made. Especially home improvement often have dirty or dusty and therefore slippery hands. Therefore, voltage testers with a rubberized grip surface are recommended. You should also make sure that the device has been tested and tested before purchasing.
