DLRO100 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 automatic or manual tests enhancing 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 V safety rating in accordance with IEC61010. A DualGround feature is available on the DLRO100X and DLRO100H, which adds to the operators' safety by grounding both sides ofthe breaker under test.
The tough design, intuitive interface and IP54 (lid open) rating ensure reliability and ease-of-use in the most arduous of conditions.
The need for accurate low resistance measurement is well known and very diverse.
Typical applications include:
Utilities & Service Contractors – commissioning new installations and regular maintenance testing
Switchgear and circuit breaker contact resistance
Busbar and cable joints
Wire and cable resistance
Lightning conductor bonding
Original Equipment Manufacturer – detecting manufacturing defects
Production test of circuit breakers – contacts and joints
Production test of high voltage switchgear
Production test of welded joints and connections
Transport – manufacturing and maintenance
Railway rolling stock ground connections and manufactured joints
Railway lines & conductor rails – commissioning and maintenance
Aircraft frame bonds and static control circuits
