Megger / Biddle DLRO10HD Digital Low Resistance Ohmmeter, Biddle 1006-657

Megger / Biddle DLRO10HD Digital Low Resistance Ohmmeter

The heavy-duty DLRO10HD digital low resistance ohmmeter can deliver 10 A current into circuits up to 250 mΩ and 1 A into circuits up to 2.5 Ω. The duration of each test can last up to 60 seconds, reducing the time required for cooling. These units have a high and low output power selection for condition diagnosis.

The DLRO10HD can be powered from its own sealed, rechargeable lead-acid battery or via mains power. This makes it suitable for continuous testing in repetitive use environments, such as production lines. Additionally, it comes in a rugged case designed for stable ground and bench operation. They are IP54 rated when operational and IP65 when the lid is closed, which is ideal for working in all weather conditions.

The DLRO10HD has five test modes: bidirectional (whereby current reversal with averaging cancels thermal EMFs), unidirectional, automatic, continuous, and inductive. You select the desired mode through a simple rotary control on the mode selection rotary switch. These rotary switches are easy to operate, even with gloved hands, and the instrument’s large, clear, backlit LCD makes for easy reading even from a distance.
