DLRO100XB – All features in the E model, with additional features such as built-in memory storage and the option to use a DC clamp for circuit breaker testing with ground protection (clamp sold separately).
A significant addition to the comprehensive range of Megger Low Resistance Ohmmeters, the DLRO100XB enables low resistance measurement, across multiple applications, in areas without access to mains power. The integral Li-Ion battery supplies a constant 100 A current for up to 200 Manual/Auto tests to enable enhanced productivity in remote locations.
With a focus on user safety, advanced design features ensure the safe operation of the instrument in the most adverse conditions, including a CAT IV 600 VAC / 500 VDC safety rating in accordance with IEC61010. The rugged design, intuitive interface and IP54 (lid open) rating ensure reliability and ease of use in the most arduous of conditions.
A new terminal adapter has been designed to enable the use of users own test leads.
