The Megger DLRO10HDX micro-ohmmeter measures low resistance values in applications ranging from railways and aircraft to
resistance of components in industry. It provides five test modes: bidirectional (current reversal with averaging cancels
thermal EMFs), unidirectional, automatic, continuous and inductive. Each test mode is selected by a simple rotary dial
on the Mode selection rotary switch. All memory functions, the ability to delete, download to PowerDB, and test results
recall are also accessible via the Range Selection rotary switch.
The DLRO10HDX is well suited to measuring thick conductors, bonds, and quality of welding because of its 10Amp range for resistance
values up to 250mΩ. It can measure any metallic joint, but users must be aware of measurement limitations depending on the 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 and thereby changing its resistance.
These units are powered from either rechargeable battery or mains power making it suitable for continuous testing in production line or repetitive
use environments.
