How to set up an Elcometer Continuous DC High Voltage Holiday Detector

When it comes to testing the porosity of protective coatings on pipelines, ballast tanks, or bridges for example - or testing for flaws in coatings on concrete - typically the high voltage or holiday detection method is used. The Continuous DC method is used to test non-conductive coatings up to 7.5mm (300mils) thick on conductive substrates. Elcometer has two continuous DC detectors: the Elcometer 236, where the high voltage supply is generated within the instrument and sent to the probe handle via a high voltage cable; and the Elcometer 266, where the high voltage supply is generated within the handle, and connected to the instrument via a low voltage cable. CONTENTS 0:42 - How Continuous DC holiday detectors work 2:13 - Getting Started 4:42 - Testing the cable connections and substrate This video introduces the Elcometer 236 DC Holiday Detector and the Elcometer 266 DC Holiday Detector, how continuous DC holiday detectors work, how to set up your continuous DC holiday detector, and how to set up your holiday detector when testing for coating flaws on concrete substrates. With your holiday detector successfully connected to the substrate and switched on, the next step is to set the voltage and sensitivity for testing the coating. WORKING SAFELY - While this video is intended as a guide for how to use the Elcometer 236 and Elcometer 266, you should always consult the operation instruction book before use, and always take extreme care when using high voltage equipment. This video is part of the Elcometer Pinhole and High Voltage Detector series. Visit https://www.elcometer.com/en/pinhole-...
