The Megger DLRO100 series, encompassing the DLRO100E, DLRO100X, and DLRO100H models, represents a sophisticated lineup of digital low resistance micro-ohmmeters designed for precision and ease of use in a variety of settings, from industrial environments to field operations. These portable, lightweight instruments are capable of delivering a substantial 100 A test current, making them exceptionally versatile for high current low resistance testing.

One of the key features of the DLRO100 series is their independence from mains power, thanks to internal rechargeable Li-ion batteries. These batteries are robust enough to support up to 200 manual or automatic tests on a single charge, providing significant autonomy and mobility. This feature is particularly advantageous for testing in remote or hard-to-access locations where power supply continuity can be a challenge.

Safety and reliability are paramount in the design of the DLRO100 series. The instruments boast novel circuitry that enhances noise immunity and ensures stable readings even in demanding operational environments. Furthermore, each model is equipped with an enclosure rated at IP54 for ingress protection, ensuring that the device remains protected against dust and water ingress even with the lid open during testing.

For enhanced operator safety, especially in adverse conditions, the DLRO100 series carries a CAT IV 600 V safety rating in accordance with IEC 61010 standards. An optional DC clamp facilitates dual ground operation via the DualGround™ system, which is especially beneficial in substations or similar settings, allowing for safe testing with both sides of the equipment under test effectively grounded.

The applications for the DLRO100 series are extensive and diverse. They are ideal for checking the resistance of busbar and cable joints, measuring wire and cable resistance, and verifying lightning conductor bonding. These instruments are also highly effective for testing switchgear and circuit breakers, both during manufacture and in field operations. Their ability to produce a smooth DC output is particularly valuable for circuit breaker tests, which require precise and stable outputs to ensure accurate diagnostics.

The DLRO100 series is equipped with a broad measuring range from 0.1 µΩ to 1.999 Ω, and a fine resolution of 0.1 µΩ. Results are easily readable on a large LCD panel, and depending on the model, data can be stored in a sizable internal memory. This data can be accessed later directly from the device or downloaded via a USB drive for detailed analysis. Certain models in the series also support features like remote operation, Bluetooth connectivity, and asset/result tagging, enhancing their functionality and user-friendliness.
