MEGGER-DLRO 600 | MICRO-OHMMETER
 
The Megger DLRO600 is a high-precision, digital low-resistance ohmmeter (micro-ohmmeter) engineered to measure very low contact resistances. Weighing less than 15 kg, it combines ultra-compact portability with high-current capability, delivering test currents from 10 A up to 600 A DC. It is ideal for use in substations, switchyards, manufacturing plants, and field service environments to verify the integrity of critical electrical connections.
 
Features & Benefits
 
High test current capability ranging from 10 A to 600 A DC for demanding low-resistance testing.
Exceptional measurement resolution down to 0.1 µΩ.
The four-terminal Kelvin measurement method eliminates test lead resistance errors.   
Multiple test modes: Normal, Continuous, and Auto for maximum operational flexibility.   
On-board memory stores up to 300 test results complete with user notes via an alphanumeric keypad.   
RS232 port for real-time data output or batch downloading to a PC or printer.   
Rugged, lightweight enclosure designed for harsh field and industrial utility environments.   
Built-in protection and continuity checks to ensure safe testing execution. 
 
Use cases
 
Testing circuit breaker and high-voltage switch contacts.   
Measuring resistance across busbar joints and high-current cable connections.   
Commissioning and routine maintenance of substation disconnectors and grounding links.
Quality control checks on production lines for heavy-duty electrical equipment.   
Verifying integrity in applications requiring high current verification to prevent overheating and joint failure.
