August 18, 2020 – Megger’s DLRO2 is a 2A hand-held, digital low-resistance ohmmeter that promises reliable results when using long test leads; it has a dedicated long test lead mode that optimizes the instrument to work with very long leads. This test lead function is able to provide up to 1A of test current into 4 Ohms resistance, making the DLRO2 (with its optional cable test reel leads) suitable for applications like testing wind turbines.

The DLRO2 is equipped with a “difference meter”, a which allows repetitive measurements to be compared with an initial reference measurement. This feature translates percentage difference to a needle/pointer movement on the unit’s display to make it easier to see the change.

The tester can display three measurements at once; useful, says Megger, when testing 3-phase equipment. It offers three test modes, including normal resistance, fast/long leads and inductive resistance, and boasts Cat IV 300 V/Cat III 600 V safety ratings.
