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

Sound alarm lives its own life.

Hi, Please ensure the sensitivity is not set to auto. We suggest starting at 50 uA and adjust accordingly on the known defect.

Good 👍

I was using 266 ( two different devices) , there is always issue with them. Tried it on epoxy coating 800um - was beeping for no reason even at lowest settings , and winylester coating over 4000um was same problem.

Hi, We suggest setting the sensitivity to manual, not automatic. Start at 50 uA and adjust as per the user manual. If you have any more questions, please get in touch at [e-mail]

Hi I used to watching your videos and learned a lot. I really appreciated. My concern is how to calibrate the DC high voltage ( continues DC & pulsed DC) prior to use or inspection, as what we do for elcometer 456, so kindly provide the information, thank you.

Thank you for your comment. The Elcometer 266 and 280 both have built-in jeep meters which monitor and, if necessary, correct the output voltage, ensuring the output voltage matches the voltage set by the user. You don't have to calibrate DC high voltage testers in the same way you would an Elcometer 456 - you simply set your test voltage to your specifications, and your sensitivity if using the Elcometer 266. For a certified calibration the instrument should be returned to an Elcometer Service Centre.

Hi, I am about to inspect a rubber lagging, however in the previous test the sound alarm is always on once I put closer the wand to the lagging. I think it is because the rubber has in its formulation a component which is conductor. what would you recommend?

Thank you for your comment. For testing slightly conductive coatings, we recommend the Elcometer 280 Pulsed DC Holiday Detector, as it uses a pulsing current to avoid the build-up of voltage charge on the structure you are testing, but it does depend how conductive the coating is.
