Use the Megger DLR010 to carry out evaluation of low resistance levels without the need to carry out complex testing.
Featuring a fully automatic test current mode, the DLRO10 makes life easier by automatically choosing an applicable testing current (up to 10A DC) and applies it to the conductor under test to generate an insulation resistance reading from 0.1μΩ to 2000Ω across seven separate ranges.
The design of the DLR010 allows it to be used either on a bench or out in the field. It is comfortable to hold in the hands or alternatively can be worn around the neck with a strap, giving easy access to all functionality when testing out in the field. An extremely large LED screen with backlight clearly shows the detected testing reading and can also be used to show an average value.
Multiple selectable testing modes are available on this low resistance tester: normal mode carries out a normal evaluation of four connections using forward and reverse currents, auto mode uses forward and reverse measurements and automatically adjusts test current, continuous mode allows repeated testing to take place over a time period and a specific inductive mode is included for use on inductive components (such as those found in motors and generators).
The following table outlines the specific functionality of the DLRO10 and the specific tests it can perform.
