Augmenting Meggerās Ducter⢠range of 10 A micro-ohmmeters, theĀ DLRO10HDX combines ultimate simplicity of operation withĀ a rugged IP65 case designed for stable ground and benchĀ operation and provides memory storage.
These units are powered from either rechargeable batteryĀ or mains power making it suitable for continuous testing inĀ production line/repetitive use environments.
Rotary switch controls are simple and easy to operate in all weather conditions and with gloved hands. A large, clear, backlit LCD display is easy to read from a distance. The DLRO10HDX provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mΩ and 1 A into measurements up to 2.5 Ω. The duration of each test may be up to 60 seconds.
The DLRO10HDX is rated CAT III 300 V provided theĀ optional terminal cover is fitted to the instrument.
History of āDucterā testing
For over 100 years the āDucter testā has been used to describe a simple test for measuring very low contact resistances and āDucterā, which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and āDucterā has since become the industry standard.
