The heavy duty DLRO10HD and DLRO10HDX digital low resistance ohmmeters can deliver a 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 be 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 and DLRO10HDX instruments can be powered from their own sealed, rechargeable lead-acid battery or via mains power. This makes them suitable for continuous testing in repetitive use environments, such as production lines. Additionally, they come 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.
Both units have 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 instruments' large, clear, backlit LCD makes for easy reading even from a distance.
The DLRO10HDX has some additional abilities over the DLRO10HD. It is rated CAT III 300 V (as long as the optional terminal cover is fitted to the instrument) and comes with onboard memory storage for up to 200 test results. The memory functions: 'delete', 'download to PowerDB', and 'recalling test results' are also accessible via the range selection rotary switch on this model.

Measuring low resistance helps identify resistance elements that have increased above acceptable values. Low resistance measurements prevent long-term damage to existing equipment and minimize energy wasted as heat. This testing reveals any restrictions in current flow that might prevent a machine from generating its full power or allow insufficient current to flow to activate protective devices in the case of a fault.
When evaluating results, it is crucial to pay attention first to repeatability. A good quality low resistance ohmmeter will provide repeatable readings within the accuracy specifications for the instrument. A typical accuracy specification is ±0.2 % of reading, ±2 LSD (least significant digit). For a reading of 1500.0, this accuracy specification allows a variance of ±3.2 (0.2 % x 1500 = 3; 2 LSD = 0.2). Additionally, the temperature coefficient must be factored into the reading if the ambient temperature deviates from the standard calibration temperature.
