Exceptional Performance for Low Resistance Testing
The Megger DLRO10HD Low Resistance Ohmmeter with DH4-C Test Lead Set delivers unparalleled performance for a wide range of applications. Equipped with the capability to output up to 10 Amps, this robust tester is encased in a durable housing, providing an IP65 ingress protection rating when closed and IP54 rating during operation, ensuring reliability even in challenging environments.
Versatile Testing Modes
Featuring multiple test modes, including Normal, Automatic, Automatic Unidirectional, Continuous, and Inductive modes, the DLRO10HD offers flexibility to suit various testing requirements. Whether initiating tests with the press of a button or automatically upon contact, this instrument ensures accurate and efficient results.
High or Low Power Selection
With user-selectable high or low power ranges, the DLRO10HD caters to diverse testing scenarios. The high-power ranges are ideal for heating weaknesses or charging inductive loads, while the low-power ranges limit power to 250 mW, ensuring precise testing without excessive heating.
Reliable and User-Friendly Design
Equipped with a large backlit liquid crystal display and rotary switch controls operable with gloved hands, the DLRO10HD prioritizes user convenience. Its high input protection up to 600V safeguards against inadvertent connections to line or UPS voltage, enhancing safety during operation.
