Non-contact voltage testers check for the presence or absence of voltage. Unlike multi-meters, non-contact voltage testers do not need to make contact with metal. Non-contact voltage testers usually feature both a visual light and an audible signal. A non-continuous light, no light, or a green light without a beep means no voltage is present. A red light with a continuous tone means voltage is present. Most models of these testers have a detection range of 50-1000V.<\/p>\n\n\n\n<p>Voltage testers work using capacitor coupling techniques.<\/p>\n\n\n\n<p>Recalling how capacitors work, two capacitors are separated by an insulator. As the electric potential increases, a voltage is drawn from one conductor through the insulating material.&nbsp;<\/p>\n\n\n\n<p>Non-contact voltage testers use two capacitors to test for the presence of voltage. One capacitor is the test object (conductor), air at the test end (insulator) and the test sensor (conductor). The second capacitor is any insulation between the tester, ground, and the tester. This simple setup draws a voltage (if any) across the capacitors and emits a red light if any voltage is present in the wires.<\/p>\n\n\n\n<p><strong>Why use a non-contact voltage tester?<\/strong><\/p>\n\n\n\n<p>A voltage tester pen is the easiest way to check the presence or absence of voltage. No light is shown when there isn\u2019t a voltage or green or discontinuous light is shown when there is no voltage. Continuous red light is shown with a beep sound when there is voltage. This is the general procedure and may vary depending on the model of the voltage pan. Read more about this <a href=\"https:\/\/rack-a-tiers.com\/blog\/what-is-non-contact-voltage-tester\/\">here<\/a>.<\/p>\n\n\n\n<p>Below is a video detailing how non-contact voltage testers work.<\/p>\n\n\n\n<p>It is therefore clear that voltage testers cannot change the lights of road signs and the video in question is misleading.<\/p>\n\n\n\n<p><strong>Road Signs<\/strong><\/p>\n\n\n\n<p>Also, there are no devices in use that allow any person to change the traffic light colors at will. Traffic lights are controlled by complex systems controlled by traffic management authorities to ensure the safe and efficient flow of traffic. Tampering with these traffic lights is illegal and dangerous.<\/p>\n\n\n\n<p>Unauthorized attempts to change traffic light colors can result in severe penalties and pose serious risks to public safety.<\/p>\n\n\n\n<p>Join us to learn more about our investigative fact findings.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.facebook.com\/factcrescendosl\/\"><strong>Facebook<\/strong><\/a><strong>&nbsp;|&nbsp;<\/strong><a href=\"https:\/\/twitter.com\/factcrescendosl\"><strong>Twitter<\/strong><\/a><strong>&nbsp;|&nbsp;<\/strong><a href=\"https:\/\/www.instagram.com\/factcrescendo_sl\/\"><strong>Instagram<\/strong><\/a><strong>&nbsp;|&nbsp;<\/strong><a href=\"https:\/\/news.google.com\/publications\/CAAqBwgKMODMpgswyNe-Aw\"><strong>Google News<\/strong><\/a><strong>&nbsp;|&nbsp;<\/strong><a href=\"https:\/\/www.tiktok.com\/@factcrescendosl\"><strong>TikTok<\/strong><\/a>&nbsp;<\/p>\n\n\n\n<p><strong>Conclusion<\/strong><\/p>\n\n\n\n<p>Our investigation shows that the video showing a foreigner switching traffic lights with a device while driving is misleading and actually shows a voltage testing device.<\/p>\n\n\n\n\t\t\t\t\t<!DOCTYPE html>\n\t\t\t\t\t<html>\n\t\t\t\t\t<head>\n\t\t\t\t\t<meta name=\"viewport\" content=\"width=device-width, initial-scale=1\">\n\t\t\t\t\t<style>\n\t\t\t\t\t.container {\n\t\t\t\t\t  border: 2px solid #000;\n\t\t\t\t\t  background-color: #eee;\n\t\t\t\t\t  border-radius: 5px;\n\t\t\t\t\t  padding: 16px;\n\t\t\t\t\t  margin: 16px 0\n\t\t\t\t\t}\n\n\t\t\t\t\t.container::after {\n\t\t\t\t\t  content: \"\";\n\t\t\t\t\t  clear: both;\n\t\t\t\t\t  display: table;\n\t\t\t\t\t}\n\n\t\t\t\t\t.container img {\n\t\t\t\t\t  float: left;\n\t\t\t\t\t  margin-right: 20px;\n\t\t\t\t\t  border-radius: 50%;\n\t\t\t\t\t}\n\n\t\t\t\t\t.container span {\n\t\t\t\t\t  font-size: 20px;\n\t\t\t\t\t  margin-right: 15px;\n\t\t\t\t\t}\n\n\t\t\t\t\t@media (max-width: 500px) {\n\t\t\t\t\t  .container {\n\t\t\t\t\t\t  text-align: center;\n\t\t\t\t\t  }\n\t\t\t\t\t  .container img {\n\t\t\t\t\t\t  margin: auto;\n\t\t\t\t\t\t  float: none;\n\t\t\t\t\t\t  display: block;\n\t\t\t\t\t  }\n\t\t\t\t\t}\n\t\t\t\t\t<\/style>\n\t\t\t\t\t<\/head>\n\t\t\t\t\t<body>\n\t\t\t\t\t<div class=\"container\">\n\t\t\t\t\t  <img decoding=\"async\" src=\"https:\/\/www.factcrescendo.com\/wp-content\/uploads\/2019\/03\/False.png\" alt=\"Avatar\" style=\"width:120px\">\n\t\t\t\t\t  <p><span>Title:<\/span>A device to switch traffic lights?<\/p>\n\t\t\t\t\t  <strong>Fact Check By:&nbsp;<a href=\"mailto:info@factcrescendo.com\" target=\"_blank\" rel=\"noreferrer noopener\">Fact Crescendo Team<\/a>&nbsp;<\/strong>\n\t\t\t\t\t  <p><strong>Result:<\/strong> False <\/p>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<\/body>\n\t\t\t\t\t<\/html>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/api.whatsapp.com\/send?phone=94771514696&#038;text=Please%20type%20your%20Name%20and%20Language:%20\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" class=\"wp-image-2481\" src=\"https:\/\/srilanka.factcrescendo.com\/wp-content\/uploads\/2019\/09\/Whats-app-sri-lanka.png\" alt=\"\"><\/a><\/figure>\n\n","protected":false},"excerpt":{"rendered":"<p>In some instances, we get to see cases where some people go astray due to jokes made by people just for entertainment and misleading posts in social media.
