DLRO10HDX digital low resistance ohmmeter

Low resistance measurement for the laboratory, the workshop, or the field.

The DLRO10HDX delivers a test current up to 10 A to measure resistance up to 250 mΩ, and 1 A for measurements up to 2.5 Ω.

The DLRO10HDX instrument 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 come in a rugged case designed for stable ground and bench operation. It is IP54 rated when operational and IP65 when the lid is closed, which is ideal for working in all weather conditions.

Applications

The DLRO10HDX measures low resistance values in applications ranging from railways and aircraft to resistance of components in industry. Any metallic joint can be measured but users must be aware of measurement limitations depending on application. For example, if a cable manufacturer plans to make resistive measurements on a thin wire, a low test current should be selected to prevent heating the wire thereby changing its resistance.

Measurements on electric motors and generators will be inductive and require the user to understand the inductive mode and charging process before a correct result is achieved.

The DLRO10HDX is well suited to measuring thick conductors, bonds and quality of welding because of its 10 A range for resistance values up to 250 mΩ.
