The Transmille EA002 Clamp Coil Adapter is designed for the calibration of both wound (AC only) & Magnetic field (hall effect) AC/DC clamp meters the current coil offers several unique features built in a robust construction. The coil is designed to immerse both jaws of the clamp meter in the magnetic field while allowing the ‘gap’ or opening where magnetic flux will escape to protrude through the coil and stay out of the strongest part of the field. This makes the reading less dependent on the position of the clamp within the coil and also the quality of the jaw closing, allowing greater confidence in the calibration.
