This is okay, but what if the caliper\u2019s potentiometer is faulty?<\/p>\n<p>\u201cIn this case the common practice is to change the complete caliper, because in the past the potentiometers were not available as a separate part \u2013 but now you can buy the potentiometer and fit it yourself, saving downtime and money.\u201d<\/p>\n<p>The difficulty, says aide automotive, lies in how to set the potentiometer to the correct starting place.<\/p>\n<p>\u201cWithout the correct tool, it\u2019s nearly impossible to set a two- or three-wire potentiometer, as it has a voltage value that goes in an endless loop, which the EBS system is monitoring then equating the voltage to a wear percentage on your dash.<\/p>\n<p>\u201cA good example is a three-wire silver potentiometer: 1.0 volts = 100 per cent new pads; 2.75 volts =75 per cent worn pads; and 3.50 volts = 0 per cent or fully worn pads.<\/p>\n<p>\u201cWhen fitting a new potentiometer you will need to set it to 0 per cent. We use the potentiometer tester which requires no training. Calibrating a potentiometer is intuitive with our tester; simply follow the on-screen display which shows you percentage, voltage and a bar graph.\u201d<\/p>\n<p>The tester is specially designed just for this job, says aide auto, offering a quick, accurate means of testing the three most common types of potentiometers.<\/p>\n<p>\u201cAll you need to do is select the type of potentiometer you are setting from the OLED display and turn the centre of the potentiometer until the bar graph is at 0 per cent, and the correct voltage is shown. It literally takes seconds.\u201d<\/p>\n<p>The potentiometer tester comes with two connecting cables, the Scania clip type and the screw-on type, and built-in batteries which are rechargeable via USB power, all in a small carry case. It is available aide automotive via the online SuperMarket here\u00a0<a title=\"HGV Brake Caliper Tester\" href=\"https:\/\/aideautomotive.com\/products\/commercial-vehicle-caliper-pot-tester\/?term=6\" target=\"_blank\" rel=\"noopener\">Commercial Vehicle Caliper Pot Tester<\/a><\/p>\n<p>Contact\u00a0<a title=\"aide automotive\" href=\"http:\/\/www.aideautomotive.com\/\" target=\"_blank\" rel=\"noopener\">aide automotive<\/a>\u00a0to discuss\u00a0<a title=\"HGV Fuel Protection\" href=\"https:\/\/news.aideautomotive.com\/articles\/low-cost-anti-truck-fuel-theft-product-range#HGV%20#Siphon\" target=\"_blank\" rel=\"noopener\">HGV Fuel Protection<\/a>\u00a0on 0115 8456471 or\u00a0<a href=\"mailto:info@aideautomotive.com\" target=\"_blank\" rel=\"noopener\">info@aideautomotive.com<\/a>\u00a0Our product range &#8211;\u00a0<a title=\"HGV Brake Testers\" href=\"https:\/\/aideautomotive.com\/products\/brakecheck-bowmonk-brake-tester\/?term=10\" target=\"_blank\" rel=\"noopener\">HGV Brake Testers<\/a>\u00a0\u2013 <a title=\"HGV Caliper Pot Tester\" href=\"https:\/\/aideautomotive.com\/products\/hgv-brake-caliper-tester\/?term=10\" target=\"_blank\" rel=\"noopener\">Caliper Pot Tester<\/a> &#8211; Trailer EBS Testers &#8211;\u00a0<a title=\"HGV Truck Trailer EBS \/ ABS Sensor Tester \" href=\"https:\/\/aideautomotive.com\/products\/ebs-abs-sensor-tester\/?term=10\" target=\"_blank\" rel=\"noopener\">HGV Truck Trailer EBS \/ ABS Sensor Tester<\/a>\u00a0&#8211; Truck \/Trailer Diagnostic Tools &#8211;\u00a0<a title=\"Midtronics Battery Testers\" href=\"https:\/\/aideautomotive.com\/products\/midtronics-mdx-600-battery-testers\/?term=10\" target=\"_blank\" rel=\"noopener\">Midtronics Battery Testers<\/a>\u00a0&#8211; Anti Siphon Devices &#8211; ISOCheck \u2013 Trailer Locks &#8211;\u00a0<a title=\"Auto Braking Reversing System\" href=\"https:\/\/aideautomotive.com\/products\/truck-reversing-auto-braking-system-backstop\/?term=9\" target=\"_blank\" rel=\"noopener\">Auto Braking Reversing System<\/a>\u00a0&#8211;\u00a0<a title=\"HGV Diesel Tank Alarms\" href=\"https:\/\/aideautomotive.com\/products\/tankguard-truck-fuel-theft-alarm\/?term=7\" target=\"_blank\" rel=\"noopener\">HGV Diesel Tank Alarms<\/a>\u00a0&#8211; Plus More<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Diagnostics equipment provider aide automotive offers a variety of solutions for commercial vehicle applications, including a potentiometer testing device. \u201cMost truck EBS systems now days monitor the pad wear percentage, and when the pads get to a pre-set wear value the warning light or display on the vehicle\u2019s dash will tell you the pads need [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":2829,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[5,210,265,12,15,16,266,267,184,22,165,23],"class_list":["post-2828","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-automotive-products","tag-automotive-tools-and-accessoriestagsaide-automotive","tag-brake-caliper","tag-brake-tester","tag-diesel-theft","tag-fuel-theft","tag-miss-fuelling","tag-potentiometers","tag-siphoning","tag-tank","tag-tankguard","tag-truck","entry","has-media"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.4 -
